DOSBox-X configuration for Screamer Rally
Raw
screamer_rally.dosbox-x-0.83.11.conf
# This is the configuration file for DOSBox-X 0.83.11. (Please use the latest version of DOSBox-X)
# Lines starting with a # are comment lines and are ignored by DOSBox-X.
# They are used to (briefly) document the effect of each option.
# To write out ALL options, use command 'config -all' with -wc or -writeconf options.
[sdl]
# fullscreen: Start DOSBox-X directly in fullscreen. (Press [F11/F12]+F to go back)
# fulldouble: Use double buffering in fullscreen. It can reduce screen flickering, but it can also result in a slow DOSBox-X.
# fullresolution: What resolution to use for fullscreen: original, desktop or a fixed size (e.g. 1024x768).
# Using your monitor's native resolution with aspect=true might give the best results.
# If you end up with small window on a large screen, try an output different from surface.
# windowresolution: Scale the window to this size IF the output device supports hardware scaling.
# (output=surface does not!)
# windowposition: Set the window position at startup in the positionX,positionY format (e.g.: 1300,200)
# display: Specify a screen/display number to use for a multi-screen setup (0 = default).
# output: What video system to use for output (openglnb = OpenGL nearest; openglpp = OpenGL perfect; ttf = TrueType font output).
# Possible values: default, surface, overlay, opengl, openglnb, openglhq, openglpp, ddraw, ttf.
# autolock: Mouse will automatically lock, if you click on the screen. (Press CTRL-F10 to unlock)
# autolock_feedback: Autolock status feedback type, i.e. visual, auditive, none.
# Possible values: none, beep, flash.
# clip_mouse_button: Select the mouse button or use arrow keys for the shared clipboard copy/paste function.
# The default mouse button is "right", which means using the right mouse button to select text, copy to and paste from the host clipboard.
# Set to "middle" to use the middle mouse button, "arrows" to use arrow keys instead of a mouse button, or "none" to disable this feature.
# Possible values: none, middle, right, arrows.
# clip_key_modifier: Change the keyboard modifier for the shared clipboard copy/paste function using a mouse button or arrow keys.
# The default modifier is "shift" (both left and right shift keys). Set to "none" if no modifier is desired.
# Possible values: none, ctrl, lctrl, rctrl, alt, lalt, ralt, shift, lshift, rshift, ctrlalt, ctrlshift, altshift, lctrlalt, lctrlshift, laltshift, rctrlalt, rctrlshift, raltshift.
# clip_paste_speed: Set keyboard speed for pasting from the shared clipboard.
# If the default setting of 30 causes lost keystrokes, increase the number.
# Or experiment with decreasing the number for applications that accept keystrokes quickly.
# sensitivity: Mouse sensitivity. The optional second parameter specifies vertical sensitivity (e.g. 100,-50).
# mouse_emulation: When is mouse emulated ?
# integration: when not locked
# locked: when locked
# always: every time
# never: at no time
# If disabled, the mouse position in DOSBox-X is exactly where the host OS reports it.
# When using a high DPI mouse, the emulation of mouse movement can noticeably reduce the
# sensitiveness of your device, i.e. the mouse is slower but more precise.
# Possible values: integration, locked, always, never.
# mouse_wheel_key: Convert mouse wheel movements into keyboard presses such as arrow keys.
# 0: disabled; 1: up/down arrows; 2: left/right arrows; 3: PgUp/PgDn keys.
# Putting a minus sign in front will disable the conversion for guest systems.
# waitonerror: Wait before closing the console if DOSBox-X has an error.
# priority: Priority levels for DOSBox-X. Second entry behind the comma is for when DOSBox-X is not focused/minimized.
# pause is only valid for the second entry.
# Possible values: lowest, lower, normal, higher, highest, pause.
# mapperfile: File used to load/save the key/event mappings from. Resetmapper only works with the default value.
# mapperfile_sdl1: File used to load/save the key/event mappings from DOSBox-X SDL1 builds. If set it will override "mapperfile" for SDL1 builds.
# mapperfile_sdl2: File used to load/save the key/event mappings from DOSBox-X SDL2 builds. If set it will override "mapperfile" for SDL2 builds.
# usescancodes: Avoid usage of symkeys, might not work on all operating systems.
# If set to "auto" (default), it is enabled for SDL1 and non-US keyboards.
# Possible values: true, false, auto.
# overscan: Width of overscan border (0 to 10). (works only if output=surface)
# titlebar: Change the string displayed in the DOSBox-X title bar.
# showbasic: If set, DOSBox-X will show basic information including the DOSBox-X version number and current running speed in the title bar.
# showdetails: If set, DOSBox-X will show the cycles count (FPS) and emulation speed relative to realtime in the title bar.
# showmenu: Whether to show the menu bar (if supported). Default true.

# language: Select another language file.
# title: Additional text to place in the title bar of the window.
# fastbioslogo: If set, DOSBox-X will skip the BIOS screen by activating fast BIOS logo mode (without 1-second pause).
# startbanner: If set (default), DOSBox-X will display the welcome banner when it starts.
# bannercolortheme: You can specify a different background color theme for the welcome banner from the default one.
# Possible values: default, black, red, green, yellow, blue, magenta, cyan, white.
# dpi aware: Set this option (auto by default) to indicate to your OS that DOSBox-X is DPI aware.
# If it is not set, Windows Vista/7/8/10 and higher may upscale the DOSBox-X window
# on higher resolution monitors which is probably not what you want.
# Possible values: true, false, 1, 0, auto.
# quit warning: Set this option to indicate whether DOSBox-X should show a warning message when the user tries to close its window.
# If set to auto (default), DOSBox-X will warn if a DOS program, game or a guest system is currently running.
# If set to autofile, DOSBox-X will warn if there are open file handles or a guest system is currently running.
# Possible values: true, false, 1, 0, auto, autofile.
# show advanced options: If set, the Configuration Tool will display all config options (including advanced ones) by default.
# hostkey: By default, DOSBox-X uses the mapper-defined host key, which defaults to F11 on Windows and F12 on other platforms.
# You may alternatively specify a host key with this setting and bypass the host key as defined in the mapper.
# This can also be done from the menu ("Main" => "Select host key").
# Possible values: ctrlalt, ctrlshift, altshift, mapper.
# mapper send key: Select the key the mapper SendKey function will send.
# Possible values: winlogo, winmenu, alttab, ctrlesc, ctrlbreak, ctrlaltdel.
# synchronize time: If set, DOSBox-X will try to automatically synchronize time with the host, unless you decide to change the date/time manually.
# keyboard hook: Use keyboard hook (currently only on Windows) to catch special keys and synchronize the keyboard LEDs with the host.
# weitek: If set, emulate the Weitek coprocessor. This option only has effect if cputype=386 or cputype=486.
# bochs debug port e9: If set, emulate Bochs debug port E9h. ASCII text written to this I/O port is assumed to be debug output, and logged.
# machine: The type of machine DOSBox-X tries to emulate.
# Possible values: hercules, cga, cga_mono, cga_rgb, cga_composite, cga_composite2, tandy, pcjr, ega, vgaonly, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe, amstrad, pc98, pc9801, pc9821, fm_towns, mcga, mda.
# captures: Directory where things like wave, midi, screenshot get captured.
# autosave: Enable the auto-save state feature. Specify a time interval in seconds, and optionally a save slot or start and end save slots.
# For example, "autosave=10 11-20" will set a 10-second time interval for auto-saving, and the save slots used will be between 11 and 20.
# You can additionally specify up to 9 programs for this feature, e.g. "autosave=10 11-20 EDIT:21-30 EDITOR:35" for "EDIT" and "EDITOR".
# Putting a minus sign (-) before the time interval causes the auto-saving function to not be activated at start.
# saveslot: Select the default save slot (1-100) to save/load states.
# savefile: Select the default save file to save/load states. If specified it will be used instead of the save slot.
# saveremark: If set, the save state feature will ask users to enter remarks when saving a state.
# forceloadstate: If set, DOSBox-X will load a saved state even if it finds there is a mismatch in the DOSBox-X version, machine type, program name and/or the memory size.
# skip encoding unchanged frames: Unchanged frames will not be sent to the video codec as a possible performance and bandwidth optimization.
# capture chroma format: Chroma format to use when capturing to H.264. 'auto' picks the best quality option.
# 4:4:4 Chroma is at full resolution. This provides the best quality, however not widely supported by editing software.
# 4:2:2 Chroma is at half horizontal resolution.
# 4:2:0 Chroma is at quarter resolution, which may cause minor color smearing.
# However, this chroma format is most likely to be compatible with video editing software.
# Possible values: auto, 4:4:4, 4:2:2, 4:2:0.
# capture format: Capture format to use when capturing video. The availability of the format depends on how DOSBox-X was compiled.
# default Use compiled-in default (avi-zmbv)
# avi-zmbv Use DOSBox-style AVI + ZMBV codec with PCM audio
# mpegts-h264 Use MPEG transport stream + H.264 + AAC audio. Resolution & refresh rate changes can be contained
# within one file with this choice, however not all software can support mid-stream format changes.
# Possible values: default, avi-zmbv, mpegts-h264.
# shell environment size: Size of the initial DOSBox-X shell environment block, in bytes. This does not affect the environment block of sub-processes spawned from the shell.
# This option has no effect unless dynamic kernel allocation is enabled.
# private area size: Set DOSBox-X private memory area size. This area contains private memory structures used by the DOS kernel.
# It is discarded when you boot into another OS. Mainline DOSBox uses 32KB. Testing shows that it is possible
# to run DOSBox with as little as 4KB. If DOSBox-X aborts with error "not enough memory for internal tables"
# then you need to increase this value.
# a20: A20 gate emulation mode.
# The on/off/on_fake/off_fake options are intended for testing and debugging DOS development,
# or to emulate obscure hardware, or to work around potential extended memory problems with DOS programs.
# on_fake/off_fake are intended to test whether a program carries out a memory test to ensure the A20
# gate is set as intended (as HIMEM.SYS does). If it goes by the gate bit alone, it WILL crash.
# This parameter is also changeable from the builtin A20GATE command.
# fast Emulate A20 gating by remapping the first 64KB @ 1MB boundary (fast, mainline DOSBox behavior)
# mask Emulate A20 gating by masking memory I/O address (accurate)
# off Lock A20 gate off (Software/OS cannot enable A20)
# on Lock A20 gate on (Software/OS cannot disable A20)
# off_fake Lock A20 gate off but allow bit to toggle (hope your DOS game tests the HMA!)
# on_fake Lock A20 gate on but allow bit to toggle
# turn off a20 gate on boot: If enabled, A20 gate is switched off when booting a guest OS.
# Enabled by default. Recommended for MS-DOS when HIMEM.SYS is not installed in the guest OS.
# If disabled, and MS-DOS does not load HIMEM.SYS, programs and features that rely on the 1MB wraparound will fail.
# cbus bus clock: C-BUS BCLK frequency (PC-98), used to emulate I/O delay.

# call binary on reset: If set, this is the path of a binary blob to load into the ROM BIOS area and execute immediately after CPU reset.
# It will be executed before the BIOS POST routine, only ONCE. The binary blob is expected either to IRET or to
# jump directly to F000:FFF0 to return control to the BIOS.
# This can be used for x86 assembly language experiments and automated testing against the CPU emulation.
# unhandled irq handler: Determines how unhandled IRQs are handled. This may help some errant DOS applications.
# Leave unset for default behavior (simple).
# simple Acknowledge the IRQ, and the master (if slave IRQ)
# mask_isr Acknowledge IRQs in service on master and slave and mask IRQs still in service, to deal with errant handlers (em-dosbox method)
# Possible values: , simple, cooperative_2nd.
# call binary on boot: If set, this is the path of a binary blob to load into the ROM BIOS area and execute immediately before booting the DOS system.
# This can be used for x86 assembly language experiments and automated testing against the CPU emulation.
# rom bios allocation max: Maximum size (top down from 1MB) allowed for ROM BIOS dynamic allocation in KB
# rom bios minimum size: Once ROM BIOS layout is finalized, trim total region down to a minimum amount in KB
# irq delay ns: IRQ delay in nanoseconds. Set to -1 to use default, 0 to disable.
# This is a more precise version of the irqdelay= setting.
# There are some old DOS games and demos that have race conditions with IRQs that need a nonzero value here to work properly.
# iodelay: I/O delay in nanoseconds for I/O port access. Set to -1 to use default, 0 to disable.
# A value of 1000 (1us) is recommended for ISA bus type delays. If your game
# or demo is not sensitive to I/O port and ISA bus timing, you can turn this option off
# (set to 0) to increase game performance.
# iodelay16: I/O delay for 16-bit transfers. -1 to use default, 0 to disable.
# iodelay32: I/O delay for 32-bit transfers. -1 to use default, 0 to disable.
# acpi: ACPI emulation, and what version of the specification to follow.
# WARNING: This option is very experimental at this time and should not be enabled unless you're willing to accept the consequences.
# Intended for use with ACPI-aware OSes including Linux and Windows 98/ME. This option will also slightly reduce available
# system memory to make room for the ACPI tables, just as real BIOSes do, and reserve an IRQ for ACPI functions.
# Possible values: off, 1.0, 1.0b, 2.0, 2.0a, 2.0b, 2.0c, 3.0, 3.0a, 3.0b, 4.0, 4.0a, 5.0, 5.0a, 6.0.
# acpi rsd ptr location: Where to store the Root System Description Pointer structure. You can have it stored in the ROM BIOS area, or the Extended Bios Data Area.
# Possible values: auto, bios, ebda.
# acpi sci irq: IRQ to assign as ACPI system control interrupt. set to -1 to automatically assign.
# acpi iobase: I/O port base for the ACPI device Power Management registers. Set to 0 for automatic assignment.
# acpi reserved size: Amount of memory at top to reserve for ACPI structures and tables. Set to 0 for automatic assignment.
# memsize: Amount of memory DOSBox-X has in megabytes.
# This value is best left at its default to avoid problems with some games,
# although other games and applications may require a higher value.
# Programs that use 286 protected mode like Windows 3.0 in Standard Mode may crash with more than 15MB.
# memsizekb: Amount of memory DOSBox-X has in kilobytes.
# This value should normally be set to 0.
# If nonzero, it is added to the memsize parameter.
# Finer grained control of total memory may be useful in
# emulating ancient DOS machines with less than 640KB of
# RAM or early 386 systems with odd extended memory sizes.
# dos mem limit: Limit DOS conventional memory to this amount. Does not affect extended memory.
# Setting this option to a value in the range 636-639 can be used to simulate modern BIOSes
# that maintain an EBDA (Extended BIOS Data Area) at the top of conventional memory.
# You may also play with this option for diagnostic purposes or to stress test DOS programs in limited memory setups.
#
# A few DOS games & demos require this option to be set:
# Majic 12 "Show": If UMBs are enabled, set this option to 639 to avoid MCB chain corruption error.
# isa memory hole at 512kb: If set, emulate an ISA memory hole at the 512KB to 640KB area (0x80000-0x9FFFF).
# reboot delay: Reboot delay. How long to pause at BIOS POST after reboot in milliseconds.
# This option is provided so that it is possible to see what the guest application
# or OS might have written to the screen before resetting the system. A value of
# -1 means to use a reasonable default.
# memalias: Memory aliasing emulation, in number of valid address bits.
# Many 386/486 class motherboards and processors prior to 1995
# suffered from memory aliasing for various technical reasons. If the software you are
# trying to run assumes aliasing, or otherwise plays cheap tricks with paging,
# enabling this option can help. Note that enabling this option can cause slight performance degredation. Set to 0 to disable.
# Recommended values when enabled:
# 24: 16MB aliasing. Common on 386SX systems (CPU had 24 external address bits)
# or 386DX and 486 systems where the CPU communicated directly with the ISA bus (A24-A31 tied off)
# 26: 64MB aliasing. Some 486s had only 26 external address bits, some motherboards tied off A26-A31
# nocachedir: If set, MOUNT commands will mount with -nocachedir (disable directory caching) by default.
# freesizecap: If set to "cap" (="true"), the value of MOUNT -freesize will apply only if the actual free size is greater than the specified value.
# If set to "relative", the value of MOUNT -freesize will change relative to the specified value.
# If set to "fixed" (="false"), the value of MOUNT -freesize will be a fixed one to be reported all the time.
# Possible values: true, false, fixed, relative, cap, 2, 1, 0.
# leading colon write protect image: If set, BOOT and IMGMOUNT commands will put an image file name with a leading colon (:) in write-protect mode.
# locking disk image mount: If set, BOOT and IMGMOUNT commands will try to lock the mounted disk image files. As a result, you cannot
# mount the same disk image files in read/write mode at the same time as this can cause possible disk corruptions.
# unmask keyboard on int 16 read: If set, INT 16h will unmask IRQ 1 (keyboard) when asked to read keyboard input.
# It is strongly recommended that you set this option if running Windows 3.11 Windows for Workgroups in DOSBox-X.
# int16 keyboard polling undocumented cf behavior: If set, INT 16h function AH=01h will also set/clear the carry flag depending on whether input was available.
# There are some old DOS games and demos that rely on this behavior to sense keyboard input, and this behavior
# has been verified to occur on some old (early 90s) BIOSes.
# allow port 92 reset: If set (default), allow the application to reset the CPU through port 92h
# enable port 92: Emulate port 92h (PS/2 system control port A). If you want to emulate a system that pre-dates the PS/2, set to 0.
# enable 1st dma controller: Emulate 1st (AT) DMA controller (default). Set to 0 if you wish to emulate a system that lacks DMA (PCjr and some Tandy systems)
# enable 2nd dma controller: Emulate 2nd (AT) DMA controller (default). Set to 0 if you wish to emulate a PC/XT system without 16-bit DMA.
# Note: mainline DOSBox automatically disables 16-bit DMA when machine=cga or machine=hercules, while DOSBox-X does not.
# allow dma address decrement: If set, allow increment & decrement modes as specified in the 8237 datasheet.
# If clear, always increment the address (as if to emulate clone 8237 implementations that skipped the inc/dec bit).
# enable 128k capable 16-bit dma: If true, DMA controller emulation models ISA hardware that permits 16-bit DMA to span 128KB.
# If false, DMA controller emulation models PCI hardware that limits 16-bit DMA to 64KB boundaries.
# If auto, the choice is made according to other factors in hardware emulation
# Possible values: true, false, 1, 0, auto.
# enable dma extra page registers: If set, emulate the extra page registers (I/O ports 0x80, 0x84-0x86, 0x88, 0x8C-0x8E), like actual hardware.
# Note that mainline DOSBox behavior is to NOT emulate these registers.
# dma page registers write-only: Normally (on AT hardware) the DMA page registers are read/write. Set this option if you want to emulate PC/XT hardware where the page registers are write-only.
# cascade interrupt never in service: If set, PIC emulation will never mark cascade interrupt as in service. This is OFF by default. It is a hack for troublesome games.
# cascade interrupt ignore in service: If true, PIC emulation will allow slave pic interrupts even if the cascade interrupt is still "in service" (common PC-98 behavior)
# If false, PIC emulation will consider cascade in-service state when deciding which interrupt to signal (common IBM PC behavior)
# If auto, setting is chosen based on machine type and other configuration.
# Possible values: true, false, 1, 0, auto.
# enable slave pic: Enable slave PIC (IRQ 8-15). Set this to 0 if you want to emulate a PC/XT type arrangement with IRQ 0-7 and no IRQ 2 cascade.
# enable pc nmi mask: Enable PC/XT style NMI mask register (0xA0). Note that this option conflicts with the secondary PIC and will be ignored if the slave PIC is enabled.
# allow more than 640kb base memory: If set, and space is available, allow conventional memory to extend past 640KB.
# For example, if machine=cga, conventional memory can extend out to 0xB800 and provide up to 736KB of RAM.
# This allows you to emulate PC/XT style memory extensions.
# enable pci bus: Enable PCI bus emulation

# vmemdelay: VGA Memory I/O delay in nanoseconds. Set to -1 to use default, 0 to disable.
# Default off. Enable this option (-1 or nonzero) if you are running a game or
# demo that needs slower VGA memory (like that of older ISA hardware) to work properly.
# If your game is not sensitive to VGA RAM I/O speed, then turning on this option
# will do nothing but cause a significant drop in frame rate which is probably not
# what you want. Recommended values -1, 0 to 2000.
# vmemsize: Amount of video memory in megabytes.
# The maximum resolution and color depth the svga_s3 will be able to display
# is determined by this value.
# -1: auto (vmemsizekb is ignored)
# 0: 512k (800x600 at 256 colors) if vmemsizekb=0
# 1: 1024x768 at 256 colors or 800x600 at 64k colors

# 4: 1600x1200 at 64k colors or 1024x768 at 16M colors
# 8: up to 1600x1200 at 16M colors
# For build engine games, use more memory than in the list above so it can
# use triple buffering and thus won't flicker.
#
# vmemsizekb: Amount of video memory in kilobytes, in addition to vmemsize.
# enable 8-bit dac: If set, allow VESA BIOS calls in IBM PC mode to set DAC width. Has no effect in PC-98 mode.
# high intensity blinking: Set to false if you want to see high-intensity background colors instead of blinking foreground text.
# This option has no effect in PC-98 and some other video modes.
# svga lfb base: If nonzero, define the physical memory address of the linear framebuffer.
# pci vga: If set, SVGA is emulated as if a PCI device (when enable pci bus=true).
# vga attribute controller mapping: This affects how the attribute controller maps colors, especially in 256-color mode.
# Some SVGA cards handle the attribute controller palette differently than most SVGA cards.
# auto Automatically pick the mapping based on the SVGA chipset.
# 4x4 Split into two 4-bit nibbles, map through AC, recombine. This is standard VGA behavior including clone SVGA cards.
# 4low Split into two 4-bit nibbles, remap only the low 4 bits, recombine. This is standard ET4000 behavior.
#
# NOTES:
# Demoscene executable 'COPPER.EXE' requires the '4low' behavior in order to display line-fading effects
# (including scrolling credits) correctly, else those parts of the demo show up as a blank screen.
#
# 4low behavior is default for ET4000 emulation.
# Possible values: , auto, 4x4, 4low, first16.
# vga bios use rom image: If set, load the VGA BIOS from the specified file (must be 1KB to 64KB in size).
# If left unset, and DOSBox-X is asked to load a VGA BIOS from a file, a file name
# is chosen automatically from the machine type. For example, Tseng ET4000 emulation
# (machine=svga_et4000) will look for et4000.bin. VGA BIOS ROM images can be dumped
# from real hardware or downloaded from the PCem ROMs collection.
#
# machine=svga_s3 TRIO64 (Ver. 1.5-07) [VGA] (S3 Incorporated).bin
# machine=svga_et4000 et4000.bin
# vga bios size override: VGA BIOS size override. Override the size of the VGA BIOS (normally 32KB in compatible or 12KB in non-compatible).
# video bios dont duplicate cga first half rom font: If set, save 4KB of EGA/VGA ROM space by pointing to the copy in the ROM BIOS of the first 128 chars
# video bios always offer 14-pixel high rom font: If set, video BIOS will always carry the 14-pixel ROM font. If clear, 14-pixel rom font will not be offered except for EGA/VGA emulation.
# video bios always offer 16-pixel high rom font: If set, video BIOS will always carry the 16-pixel ROM font. If clear, 16-pixel rom font will not be offered except for VGA emulation.
# video bios enable cga second half rom font: If set, and emulating CGA/PCjr/Tandy, automatically provide the second half of the 8x8 ROM font.
# This setting is ignored for EGA/VGA emulation. If not set, you will need a utility like GRAFTABL.COM to load the second half of the ROM font for graphics.
# NOTE: if you disable the 14 & 16 pixel high font AND the second half when machine=cga, you will disable video bios completely.
# forcerate: Force the VGA framerate to a specific value(ntsc, pal, or specific hz), no matter what
# sierra ramdac: Whether or not to emulate a Sierra or compatible RAMDAC at port 3C6h-3C9h.
# Some DOS games expect to access port 3C6h to enable highcolor/truecolor SVGA modes on older chipsets.
# Disable if you wish to emulate SVGA hardware that lacks a RAMDAC or (depending on the chipset) does
# not emulate a RAMDAC that is accessible through port 3C6h. This option has no effect for non-VGA video hardware.
# sierra ramdac lock 565: When emulating High Sierra highcolor RAMDAC, assume 5:6:5 at all times if set. Else,
# bit 6 of the DAC command selects between 5:5:5 and 5:6:5. Set this option for demos or
# games that got the command byte wrong (MFX Transgrassion 2) or any other demo that is
# not rendering highcolor 16bpp correctly.
# page flip debug line: VGA debugging switch. If set, an inverse line will be drawn on the exact scanline that the CRTC display offset registers were written.
# This can be used to help diagnose whether or not the DOS game is page flipping properly according to vertical retrace if the display on-screen is flickering.
# vertical retrace poll debug line: VGA debugging switch. If set, an inverse green dotted line will be drawn on the exact scanline that the CRTC status port (0x3DA) was read.
# This can be used to help diagnose whether the DOS game is propertly waiting for vertical retrace.
# cgasnow: When machine=cga, determines whether or not to emulate CGA snow in 80x25 text mode
# vga 3da undefined bits: VGA status port 3BA/3DAh only defines bits 0 and 3. This setting allows you to assign a bit pattern to the undefined bits.
# The purpose of this hack is to deal with demos that read and handle port 3DAh in ways that might crash if all are zero.
# rom bios 8x8 CGA font: If set, or mainline DOSBox compatible BIOS mapping, a legacy 8x8 CGA font (first 128 characters) is stored at 0xF000:0xFA6E. DOS programs that do not use INT 10h to locate fonts might require that font to be located there.
# rom bios video parameter table: If set, or mainline DOSBox compatible BIOS mapping, DOSBox-X will emulate the video parameter table and assign that to INT 1Dh. If clear, table will not be provided.
# int 10h points at vga bios: If set, INT 10h points at the VGA BIOS. If clear, INT 10h points into the system BIOS. This option only affects EGA/VGA/SVGA emulation.
# This option is needed for some older DOS applications that make additional checks before detecting EGA/VGA hardware (SuperCalc).
# unmask timer on int 10 setmode: If set, INT 10h will unmask IRQ 0 (timer) when setting video modes.
# vesa bank switching window mirroring: If set, bank switch (windowed) VESA BIOS modes will ignore the window selection when asked
# to bank switch. Requests to control either Window A or Window B will succeed. This is needed
# for some demoscene productions with SVGA support that assume Window B is available, without
# which graphics do not render properly.
# If clear, Window B is presented as not available and attempts to use it will fail. Only Window A
# will be available, which is also DOSBox SVN behavior.
# vesa bank switching window range check: Controls whether calls to bank switch (set the window number) through the VESA BIOS apply
# range checking. If set, out of range window numbers will return with an error code. This
# is also DOSBox SVN behavior. If clear, out of range window numbers are silently truncated
# to a number within range of available video memory and allowed to succeed.
# This is needed for some demoscene productions that rely on the silent truncation to render
# correctly without which drawing errors occur (e.g. end credits of Pill by Opiate)
# vesa zero buffer on get information: This setting affects VESA BIOS function INT 10h AX=4F00h. If set, the VESA BIOS will zero the
# 256-byte buffer defined by the standard at ES:DI, then fill in the structure. If clear, only
# the structure members will be filled in, and memory outside the initial 20-32 bytes will remain
# unmodified. This setting is ON by default. Some very early 1990s DOS games that support VESA
# BIOS standards may need this setting turned OFF if the programmer did not provide enough space
# for the entire 256 byte structure and the game crashes if it detects VESA BIOS extensions.
# Needed for:
# GETSADAM.EXE
# vesa set display vsync: Whether to wait for vertical retrace if VESA Set Display Address is used to pan the display.
# The default value -1 will wait if svga_oldvbe, or not otherwise. 0 means not to wait.
# 1 means always to wait. This affects only subfunction 0x00. Subfunction 0x80 will always wait
# as specified in the VESA BIOS standard.
# It is recommended to set this to 1 for VBETEST.EXE so that the panning test and information does not
# go by too fast.
# vesa lfb base scanline adjust: If non-zero, the VESA BIOS will report the linear framebuffer offset by this many scanlines.
# This does not affect the linear framebuffer's location. It only affects the linear framebuffer
# location reported by the VESA BIOS. Set to nonzero for DOS games with sloppy VESA graphics pointer management.
# MFX "Melvindale" (1996): Set this option to 2 to center the picture properly.
# vesa map non-lfb modes to 128kb region: If set, VESA BIOS SVGA modes will be set to map 128KB of video memory to A0000-BFFFF instead of
# 64KB at A0000-AFFFF. This does not affect the SVGA window size or granularity.
# Some games or demoscene productions assume that they can render into the next SVGA window/bank
# by writing to video memory beyond the current SVGA window address and will not appear correctly
# without this option.
# ega per scanline hpel: If set, EGA emulation allows changing hpel per scanline. This is reportedly the behavior
# of IBM EGA hardware according to DOSBox SVN and on by default. If clear, EGA emulation
# latches hpel on vertical retrace end (like VGA does), which may have been EGA clone behavior
# that some games were written against. Commander Keen episodes 4-6 need this option set to false when machine=ega.
# This option affects only EGA emulation. To change VGA hpel behavior, use the 'allow hpel effects' setting instead.
# allow hpel effects: If set, allow the DOS demo or program to change the horizontal pel (panning) register per scanline.
# Some early DOS demos use this to create waving or sinus effects on the picture. Not very many VGA
# chipsets allow this, so far, only ATI chipsets are known to support this effect. Disabled by default.
# allow hretrace effects: If set, allow the DOS demo or program to make the picture wavy by playing with the 'start horizontalretrace' register of the CRTC during the active picture. Some early DOS demos (Copper by Surprise!productions) need this option set for some demo effects to work. Disabled by default.
# hretrace effect weight: If emulating hretrace effects, this parameter adds 'weight' to the offset to smooth it out.
# the larger the number, the more averaging is applied. This is intended to emulate the inertia
# of the electron beam in a CRT monitor
# vesa modelist cap: IF nonzero, the VESA modelist is capped so that it contains no more than the specified number of video modes.
# vesa modelist width limit: IF nonzero, VESA modes with horizontal resolution higher than the specified pixel count will not be listed.
# This is another way the modelist can be capped for DOS applications that have trouble with long modelists.
# vesa modelist height limit: IF nonzero, VESA modes with vertical resolution higher than the specified pixel count will not be listed.
# This is another way the modelist can be capped for DOS applications that have trouble with long modelists.
# vesa vbe put modelist in vesa information: If set, the VESA modelist is placed in the VESA information structure itself when the DOS application
# queries information on the VESA BIOS. Setting this option may help with some games, though it limits
# the mode list reported to the DOS application.
# vesa vbe 1.2 modes are 32bpp: If set, truecolor (16M color) VESA BIOS modes in the 0x100-0x11F range are 32bpp. If clear, they are 24bpp.
# Some DOS games and demos assume one bit depth or the other and do not enumerate VESA BIOS modes, which is why this
# option exists.
# allow low resolution vesa modes: If set, allow low resolution VESA modes (320x200x16/24/32bpp and so on). You could set this to false to simulate
# SVGA hardware with a BIOS that does not support the lowres modes for testing purposes.
# allow explicit 24bpp vesa modes: If set, additional 24bpp modes are listed in the modelist regardless whether modes 0x100-0x11F are
# configured to be 24bpp or 32bpp. Setting this option can provide the best testing and development
# environment for new retro DOS code. If clear, 24bpp will only be available in the 0x100-0x11F range
# if the "vesa vbe 1.2 modes are 32bpp" is false. Setting to false helps to emulate typical SVGA
# hardware in which either 24bpp is supported, or 32bpp is supported, but not both. Disabled by default.
# allow high definition vesa modes: If set, offer HD video modes in the VESA modelist (such as 1280x720 aka 720p or 1920x1080 aka 1080p).
# This option also offers 4:3 versions (960x720 and 1440x1080) for DOS games that cannot properly handle
# a 16:9 aspect ratio, and several other HD modes. The modes enabled by this option are still limited by the
# width and height limits and available video memory.
# This is unusual for VESA BIOSes to do and is disabled by default.
# allow unusual vesa modes: If set, unusual (uncommon) modes are added to the list. The modes reflect uncommon resolutions
# added by external drivers (UNIVBE), some VESA BIOSes, some laptop and netbook displays, and
# some added by DOSBox-X for additional fun. Disabled by default.
# allow 32bpp vesa modes: If the DOS game or demo has problems with 32bpp VESA modes, set to 'false'
# allow 24bpp vesa modes: If the DOS game or demo has problems with 24bpp VESA modes, set to 'false'
# allow 16bpp vesa modes: If the DOS game or demo has problems with 16bpp VESA modes, set to 'false'
# allow 15bpp vesa modes: If the DOS game or demo has problems with 15bpp VESA modes, set to 'false'
# allow 8bpp vesa modes: If the DOS game or demo has problems with 8bpp VESA modes, set to 'false'
# allow 4bpp vesa modes: If the DOS game or demo has problems with 4bpp VESA modes, set to 'false'.
# These modes have the same 16-color planar memory layout as standard VGA, but
# at SVGA resolution.
# allow 4bpp packed vesa modes: If the DOS game or demo has problems with 4bpp packed VESA modes, set to 'false'.
# 4bpp (16-color) packed is an unusual novelty mode only seen on specific Chips & Tech 65550
# VESA BIOSes such as the one in a Toshiba Libretto laptop. Disabled by default.
# allow tty vesa modes: If the DOS game or demo has problems with text VESA modes, set to 'false'
# double-buffered line compare: This setting affects the VGA Line Compare register. Set to false (default value) to emulate most VGA behavior
# Set to true for the value to latch once at the start of the frame.
# ignore vblank wraparound: DOSBox-X can handle active display properly if games or demos reprogram vertical blanking to end in the active picture area.
# If the wraparound handling prevents the game from displaying properly, set this to false. Out of bounds vblank values will be ignored.
#
# ignore extended memory bit: Some DOS applications use VGA 256-color mode but accidentally clear the extended memory
# bit originally defined to indicate whether EGA hardware has more than 64KB of RAM.
# Setting this option can correct for that. Needed for Mr. Blobby.
# enable vga resize delay: If the DOS game you are running relies on certain VGA raster tricks that affect active display area, enable this option.
# This adds a delay between VGA mode changes and window updates. It also means that if you are capturing a demo or game,
# that your capture will also show a few garbled frames at any point mode changes occur, which is why this option is disabled
# by default. If you intend to run certain DOS games and demos like DoWhackaDo, enable this option.
# resize only on vga active display width increase: If set, changes to the Display End register of the CRTC do not trigger DOSBox-X to resize its window
# IF the value written is less than the current value. Some demos like DoWhackaDo need this option set
# because of the way its raster effects work. If the DOSBox-X window rapidly changes size during a demo
# try setting this option. Else, leave it turned off. Changes to other VGA CRTC registers will trigger
# a DOSBox-X mode change as normal regardless of this setting.
# vga palette update on full load: If set, all three bytes of the palette entry must be loaded before taking the color,
# which is fairly typical SVGA behavior. If not set, partial changes are allowed.
# ignore odd-even mode in non-cga modes: Some demoscene productions use VGA Mode X but accidentally enable odd/even mode.
# Setting this option can correct for that and render the demo properly.
# This option forces VGA emulation to ignore odd/even mode except in text and CGA modes.

[render]
# frameskip: How many frames DOSBox-X skips before drawing one.
# alt render: If set, use a new experimental rendering engine
# aspect: Aspect ratio correction mode. Can be set to the following values:
# 'false' (default):
# 'direct3d'/opengl outputs: image is simply scaled to full window/fullscreen size, possibly resulting in disproportional image
# 'surface' output: it does no aspect ratio correction (default), resulting in disproportional images if VGA mode pixel ratio is not 4:3
# 'true':
# 'direct3d'/opengl outputs: uses output driver functions to scale / pad image with black bars, correcting output to proportional 4:3 image
# In most cases image degradation should not be noticeable (it all depends on the video adapter and how much the image is upscaled).
# Should have none to negligible impact on performance, mostly being done in hardware
# For the pixel-perfect scaling (output=openglpp), it is recommended to enable this whenever the emulated display has an aspect ratio of 4:3
# 'surface' output: inherits old DOSBox aspect ratio correction method (adjusting rendered image line count to correct output to 4:3 ratio)
# Due to source image manipulation this mode does not mix well with scalers, i.e. multiline scalers like hq2x/hq3x will work poorly
# Slightly degrades visual image quality. Has a tiny impact on performance
# When using xBRZ scaler with 'surface' output, aspect ratio correction is done by the scaler itself, so none of the above apply
# Possible values: false, true, 0, 1, yes, no, nearest, bilinear.
# char9: Allow 9-pixel wide text mode fonts.
# euro: Display Euro symbol instead of the specified ASCII character (33-255).
# For example, setting it to 128 allows Euro symbol to be displayed instead of C-cedilla.
# doublescan: If set, doublescanned output emits two scanlines for each source line, in the
# same manner as the actual VGA output (320x200 is rendered as 640x400 for example).
# If clear, doublescanned output is rendered at the native source resolution (320x200 as 320x200).
# This affects the raster PRIOR to the software or hardware scalers. Choose wisely.
# For pixel-perfect scaling (output=openglpp), it is recommended to turn this option off.
# scaler: Scaler used to enlarge/enhance low resolution modes. If 'forced' is appended,
# then the scaler will be used even if the result might not be desired.
# To fit a scaler in the resolution used at full screen may require a border or side bars.

# advinterp2x, advinterp3x, advmame2x, advmame3x, rgb2x, rgb3x, scan2x, scan3x, tv2x, tv3x, sharp.
# pixelshader: Set Direct3D pixel shader program (effect file must be in Shaders subdirectory). If 'forced' is appended,
# then the pixel shader will be used even if the result might not be desired.
# xbrz slice: Number of screen lines to process in single xBRZ scaler taskset task, affects xBRZ performance, 16 is the default
# xbrz fixed scale factor: To use fixed xBRZ scale factor (i.e. to attune performance), set it to 2-6, 0 - use automatic calculation (default)
# xbrz max scale factor: To cap maximum xBRZ scale factor used (i.e. to attune performance), set it to 2-6, 0 - use scaler allowed maximum (default)

# For example, setting it to "consola" or "consola.ttf" will use the Consola font; similar for other TTF fonts.
# ttf.fontbold: You can optionally specify a bold TrueType font for use with the TTF output that will render the bold text style.
# It requires a word processor be set with the ttf.wp option, and this actual bold font will be used for the bold style.
# For example, setting it to "consolab" or "consolab.ttf" will use the Consolab font; similar for other TTF fonts.
# ttf.fontital: You can optionally specify an italic TrueType font for use with the TTF output that will render the italic text style.
# It requires a word processor be set with the ttf.wp option, and this actual italic font will be used for the italic style.
# For example, setting it to "consolai" or "consolai.ttf" will use the Consolai font; similar for other TTF fonts.
# ttf.fontboit: You can optionally specify a bold italic TrueType font for use with the TTF output that will render the bold italic text style.
# It requires a word processor be set with the ttf.wp option, and this actual bold-italic font will be used for the bold-italic style.

# ttf.wpbg: You can optionally specify a color to match the background color of the specified word processor for the TTF output.
# ttf.bold: If set, DOSBox-X will display bold text in visually (requires a word processor be set) for the TTF output.
# This is done either with the actual bold font specified by the ttf.fontbold option, or by making it bold automatically.
# ttf.italic: If set, DOSBox-X will display italicized text visually (requires a word processor be set) for the TTF output.
# This is done either with the actual italic font specified by the ttf.fontital option, or by slanting the characters automatically.

# fpu: Enable FPU emulation
# segment limits: Enforce segment limits
# double fault: Emulate double fault exception
# reset on triple fault: Reset CPU on triple fault condition (failure to handle double fault)
# always report double fault: Always report (to log file) double faults if set. Else, a double fault is reported only once. Set this option for debugging purposes.
# always report triple fault: Always report (to log file) triple faults if set. Else, a triple fault is reported only once. Set this option for debugging purposes.
# report fdiv bug: If set, the FDIV bug will be reported with the cputype=pentium setting.
# enable msr: Allow RDMSR/WRMSR instructions. This option is only meaningful when cputype=pentium.
# WARNING: Leaving this option enabled while installing Windows 95/98/ME can cause crashes.
# enable cmpxchg8b: Enable Pentium CMPXCHG8B instruction. Enable this explicitly if using software that uses this instruction.
# You must enable this option to run Windows ME because portions of the kernel rely on this instruction.
# ignore undefined msr: Ignore RDMSR/WRMSR on undefined registers. Normally the CPU will fire an Invalid Opcode exception in that case.
# This option is off by default, enable if using software or drivers that assumes the presence of
# certain MSR registers without checking. If you are using certain versions of the 3dfx Glide drivers for MS-DOS
# you will need to set this to TRUE as 3dfx appears to have coded GLIDE2X.OVL to assume the presence
# of Pentium Pro/Pentium II MTRR registers.
# WARNING: Leaving this option enabled while installing Windows 95/98/ME can cause crashes.
# interruptible rep string op: if nonzero, REP string instructions (LODS/MOVS/STOS/INS/OUTS) are interruptible (by interrupts or other events).
# if zero, REP string instructions are carried out in full before processing events and interrupts.
# Set to -1 for a reasonable default setting based on cpu type and other configuration.
# A setting of 0 can improve emulation speed at the expense of emulation accuracy.
# A nonzero setting (1-8) may be needed for DOS games and demos that use the IRQ 0 interrupt to play digitized samples
# while doing VGA palette animation at the same time (use case of REP OUTS), where the non-interruptible version
# would cause an audible drop in audio pitch.
# dynamic core cache block size: dynamic core cache block size. default value is 32. change this value carefully.
# according to forum discussion, setting this to 1 can aid debugging, however doing so
# also causes problems with 32-bit protected mode DOS games and reduces the performance
# of the dynamic core.
#
# cputype: CPU Type used in emulation. auto emulates a 486 which tolerates Pentium instructions.
# Possible values: auto, 8086, 8086_prefetch, 80186, 80186_prefetch, 286, 286_prefetch, 386, 386_prefetch, 486old, 486old_prefetch, 486, 486_prefetch, pentium, pentium_mmx, ppro_slow.
# cycles: Amount of instructions DOSBox-X tries to emulate each millisecond.
# Setting this value too high results in sound dropouts and lags.
# Cycles can be set in 3 ways:
# 'auto' tries to guess what a game needs.
# It usually works, but can fail for certain games.
# 'fixed #number' will set a fixed amount of cycles. This is what you usually
# need if 'auto' fails (Example: fixed 4000).
# 'max' will allocate as much cycles as your computer is able to
# handle.
# Possible values: auto, fixed, max.
# cycleup: Amount of cycles to decrease/increase with the mapped keyboard shortcut.
# cycledown: Setting it lower than 100 will be a percentage.
# cycle emulation percentage adjust: The percentage adjustment for use with the "Emulate CPU speed" feature. Default is 0 (no adjustment), but you can adjust it (between -25% and 25%) if necessary.
# use dynamic core with paging on: Allow dynamic cores (dynamic_x86 and dynamic_rec) to be used with 386 paging enabled.
# If the dynamic_x86 core is set, this allows Windows 9x/ME to run properly, but may somewhat decrease the performance.
# If the dynamic_rec core is set, this disables the dynamic core if the 386 paging functions are currently enabled.
# If set to auto, this option will be enabled depending on if the 386 paging and a guest system are currently active.
# Possible values: true, false, 1, 0, auto.
# ignore opcode 63: When debugging, do not report illegal opcode 0x63.
# Enable this option to ignore spurious errors while debugging from within Windows 3.1/9x/ME.
# apmbios: Emulate Advanced Power Management (APM) BIOS calls.
# apmbios pnp: If emulating ISA PnP BIOS, announce APM BIOS in PnP enumeration.
# Warning: this can cause Windows 95 OSR2 and later to enumerate the APM BIOS twice and cause problems.

# apmbios allow 16-bit protected mode: Allow guest OS to connect from 16-bit protected mode.
# apmbios allow 32-bit protected mode: Allow guest OS to connect from 32-bit protected mode.
# If you want power management in Windows 95/98/ME (beyond using the APM to shutdown the computer) you MUST enable this option.
# Windows 95/98/ME does not support the 16-bit real and protected mode APM BIOS entry points.
# Please note at this time that 32-bit APM is unstable under Windows ME.
# integration device: Enable DOSBox-X integration I/O device. This can be used by the guest OS to match mouse pointer position, for example. EXPERIMENTAL!
# integration device pnp: List DOSBox-X integration I/O device as part of ISA PnP enumeration. This has no purpose yet.
# isapnpbios: Emulate ISA Plug & Play BIOS. Enable if using DOSBox-X to run a PnP aware DOS program or if booting Windows 9x.
# Do not disable if Windows 9x is configured around PnP devices, you will likely confuse it.

# For more information: https://www.vogons.org/viewtopic.php?f=62&t=61098&start=280
# pic unmask irq: Start the DOS virtual machine with the Sound Blaster IRQ already unmasked at the PIC.
# Some early DOS games/demos that support Sound Blaster expect the IRQ to fire but make
# no attempt to unmask the IRQ. If audio cuts out no matter what IRQ you try, then try
# setting this option.
# Option is needed for:
# Public NMI "jump" demo (1992)
# enable speaker: Start the DOS virtual machine with the Sound Blaster speaker enabled.
# Sound Blaster Pro and older cards have a speaker disable/enable command.
# Normally the card boots up with the speaker disabled. If a DOS game or demo
# attempts to play without enabling the speaker, set this option to true to
# compensate. This setting has no meaning if emulating a Sound Blaster 16 card.
# enable asp: If set, emulate the presence of the Sound Blaster 16 Advanced Sound Processor/Creative Sound Processor chip.
# NOTE: This only emulates it's presence and the basic DSP commands to communicate with it. Actual ASP/CSP functions are not yet implemented.
# disable filtering: By default DOSBox-X filters Sound Blaster output to emulate lowpass filters and analog output limitations.
# Set this option to true to disable filtering. Note that doing so disables emulation of the Sound Blaster Pro
# output filter and ESS AudioDrive lowpass filter.
# dsp write buffer status must return 0x7f or 0xff: If set, force port 22Ch (DSP write buffer status) to return 0x7F or 0xFF. If not set, the port
# may return 0x7F or 0xFF depending on what type of Sound Blaster is being emulated.
# Set this option for some early DOS demos that make that assumption about port 22Ch.
# Option is needed for:
# Overload by Hysteria (1992) - Audio will crackle/saturate (8-bit overflow) except when sbtype=sb16
# pre-set sbpro stereo: Start the DOS virtual machine with the Sound Blaster Pro stereo bit set (in the mixer).
# A few demos support Sound Blaster Pro but forget to set this bit.
# Option is needed for:
# Inconexia by Iguana (1993)
# sbmixer: Allow the Sound Blaster mixer to modify the DOSBox-X mixer.
# oplmode: Type of OPL emulation. On 'auto' the mode is determined by the 'sbtype' setting.
# All OPL modes are AdLib-compatible, except for 'cms' (set 'sbtype=none' with 'cms' for a Game Blaster).
# Possible values: auto, cms, opl2, dualopl2, opl3, opl3gold, none, hardware, hardwaregb.
# adlib force timer overflow on detect: If set, Adlib/OPL emulation will signal 'overflow' on timers after 50 I/O reads.
# This is a temporary hack to work around timing bugs noted in DOSBox-X. Certain
# games (Wolfenstein 3D) poll the Adlib status port a fixed number of times assuming
# that the poll loop takes long enough for the Adlib timer to run out. If the game
# cannot reliably detect Adlib at higher cycles counts, but can reliably detect at
# lower cycles counts, set this option.
# NOTE: Technically this decreases emulation accuracy, however it also reflects the
# fact that DOSBox-X's I/O timing code needs some work to better match the
# slowness of the ISA bus per I/O read in consideration of DOS games. So this
# option is ON by default.
# oplemu: Provider for the OPL emulation. 'compat' might provide better quality.
# 'nuked' is the most accurate (but the most CPU-intensive). See oplrate as well.
# Possible values: default, compat, fast, nuked, mame, opl2board, opl3duoboard.
# oplrate: Sample rate of OPL music emulation. Use 49716 for highest quality (set the mixer rate accordingly).
# Possible values: 44100, 49716, 48000, 32000, 22050, 16000, 11025, 8000.
# oplport: Serial port of the OPL2 Audio Board when oplemu=opl2board, opl2mode will become 'opl2' automatically.
# hardwarebase: base address of the real hardware Sound Blaster:
# 210,220,230,240,250,260,280
# force dsp auto-init: Treat all single-cycle DSP commands as auto-init to keep playback going.
# This option is a workaround for DOS games or demos that use single-cycle DSP playback commands and
# have problems with missing the Sound Blaster IRQ under load. Do not enable unless you need this workaround.
# Needed for:
# - Extreme "lunatic" demo (1993)
# force goldplay: Always render Sound Blaster output sample-at-a-time. Testing option. You probably don't want to enable this.
# goldplay: Enable goldplay emulation.
# goldplay stereo: Enable workaround for goldplay stereo playback. Many DOS demos using this technique
# don't seem to know they need to double the frequency when programming the DSP time constant for Pro stereo output.
# If stereo playback seems to have artifacts consider enabling this option. For accurate emulation of Sound Blaster
# hardware, disable this option.
# dsp require interrupt acknowledge: If set, the DSP will halt DMA playback until IRQ acknowledgement occurs even in auto-init mode (SB16 behavior).
# If clear, IRQ acknowledgement will have no effect on auto-init playback (SB Pro and earlier & clone behavior)
# If set to 'auto' then behavior is determined by sbtype= setting.
# This is a setting for hardware accuracy in emulation. If audio briefly plays then stops then your DOS game
# and it's not using IRQ (but using DMA), try setting this option to 'false'
# dsp write busy delay: Amount of time in nanoseconds the DSP chip signals 'busy' after writing to the DSP (port 2xCh). Set to -1 to use card-specific defaults.
# WARNING: Setting the value too high (above 20000ns) may have detrimental effects to DOS games that use IRQ 0 and DSP command 0x10 to play audio.
# Setting the value way too high (above 1000000ns) can cause significant lag in DOS games.
# blaster environment variable: Whether or not to set the BLASTER environment variable automatically at startup
# sample rate limits: If set (default), limit DSP sample rate to what real hardware is limited to
# instant direct dac: If set, direct DAC output commands are instantaneous. This option is intended as a quick fix for
# games or demos that play direct DAC music/sound from the IRQ 0 timer who a) write the DSP command
# and data without polling the DSP to ensure it's ready or b) can get locked into the IRQ 0 handler
# waiting for DSP status when instructed to play at or beyond the DSP's maximum direct DAC sample rate.
# This fix allows broken Sound Blaster code to work and should not be enabled unless necessary.
# stereo control with sbpro only: Default on. If set, Sound Blaster Pro stereo is not available when emulating sb16 or sb16vibra.
# If clear, sb16 emulation will honor the sbpro stereo bit. Note that Creative SB16 cards do not
# honor the stereo bit, and this option allows DOSBox-X emulate that fact. Accuracy setting.
# dsp busy cycle rate: Sound Blaster 16 DSP chips appear to go busy periodically at some high clock rate
# whether the DSP is actually doing anything for the system or not. This is an accuracy
# option for Sound Blaster emulation. If this option is nonzero, it will be interpreted
# as the busy cycle rate in Hz. If zero, busy cycle will not be emulated. If -1, sound
# blaster emulation will automatically choose a setting based on the sbtype= setting
# dsp busy cycle always: If set, the DSP busy cycle always happens. If clear, DSP busy cycle only happens when
# audio playback is running. Default setting is to pick according to the sound card.
# dsp busy cycle duty: If emulating SB16 busy cycle, this value (0 to 100) controls the duty cycle of the busy cycle.
# If this option is set to -1, Sound Blaster emulation will choose a value automatically according
# to sbtype=. If 0, busy cycle emulation is disabled.
# io port aliasing: If set, Sound Blaster ports alias by not decoding the LSB of the I/O port.
# This option only applies when sbtype is set to sb1 or sb2 (not SBPro or SB16).
# This is a hack for the Electromotive Force 'Internal Damage' demo which apparently
# relies on this behavior for Sound Blaster output and should be enabled for accuracy in emulation.

# ignore channel count while active: Ignore writes to the active channel count register when the DAC is enabled (bit 1 of GUS reset)
# This is a HACK for demoscene prod 'Ice Fever' without which the music sounds wrong.
# According to current testing real hardware does not behave this way.
# pic unmask irq: Start the DOS virtual machine with the GUS IRQ already unmasked at the PIC.
# startup initialized: If set, start the GF1 in a fully initialized state (as if ULTRINIT had been run).
# If clear, leave the card in an uninitialized state (as if cold boot).
# Some DOS games or demoscene productions will hang or fail to use the Ultrasound hardware
# because they assume the card is initialized and their hardware detect does not fully initialize the card.
# dma enable on dma control polling: If set, automatically enable GUS DMA transfer bit in specific cases when the DMA control register is being polled.
# THIS IS A HACK. Some games and demoscene productions need this hack to avoid hanging while uploading sample data

# xms: Enable XMS support.
# xms handles: Number of XMS handles available for the DOS environment, or 0 to use a reasonable default
# shell configuration as commands: Allow entering dosbox-x.conf configuration parameters as shell commands to get and set settings.
# This is disabled by default to avoid conflicts between commands and executables.
# It is recommended to get and set dosbox-x.conf settings using the CONFIG command instead.
# Compatibility with DOSBox SVN can be improved by enabling this option.
# hma: Report through XMS that HMA exists (not necessarily available)
# hma allow reservation: Allow TSR and application (anything other than the DOS kernel) to request control of the HMA.
# They will not be able to request control however if the DOS kernel is configured to occupy the HMA (DOS=HIGH)
# hard drive data rate limit: Slow down (limit) hard disk throughput. This setting controls the limit in bytes/second.
# Set to 0 to disable the limit, or -1 to use a reasonable default.
# drive z is remote: If set, DOS will report drive Z as remote. If not set, DOS will report drive Z as local.
# If auto (default), DOS will report drive Z as remote or local depending on the program.
# Set this option to true to prevent SCANDISK.EXE from attempting scan and repair drive Z:
# which is impossible since Z: is a virtual drive not backed by a disk filesystem.
# Possible values: true, false, 1, 0, auto.
# drive z hide files: The files listed here (separated by space) will be either hidden or removed from the Z drive.
# Files with leading forward slashs (e.g. "/A20GATE.COM") will be hidden files (DIR /A will list them).
# hma minimum allocation: Minimum allocation size for HMA in bytes (equivalent to /HMAMIN= parameter).
# ansi.sys: If set (by default), ANSI.SYS emulation is on. If clear, ANSI.SYS is not emulated and will not appear to be installed.
# NOTE: This option has no effect in PC-98 mode where MS-DOS systems integrate ANSI.SYS into the DOS kernel.
# log console: If set, log DOS CON output to the log file.
# dos sda size: SDA (swappable data area) size, in bytes. Set to 0 to use a reasonable default.
# hma free space: Controls the amount of free space available in HMA. This setting is not meaningful unless the
# DOS kernel occupies HMA and the emulated DOS version is at least 5.0.
# cpm compatibility mode: This controls how the DOS kernel sets up the CP/M compatibility code in the PSP segment.
# Several options are provided to emulate one of several undocumented behaviors related to the CP/M entry point.
# If set to auto, DOSBox-X will pick the best option to allow it to work properly.
# Unless set to 'off', this option will require the DOS kernel to occupy the first 256 bytes of the HMA memory area
# to prevent crashes when the A20 gate is switched on.
# auto Pick the best option
# off Turn off the CP/M entry point (program will abort if called)
# msdos2 MS-DOS 2.x behavior, offset field also doubles as data segment size
# msdos5 MS-DOS 5.x behavior, entry point becomes one of two fixed addresses
# direct Non-standard behavior, encode the CALL FAR directly to the entry point rather than indirectly
# Possible values: auto, off, msdos2, msdos5, direct.
# share: Report SHARE.EXE as resident. This will allow file locking to be performed, although not all SHARE functions are emulated.
# file access tries: If a positive integer is set, DOSBox-X will try to read/write/lock files directly on mounted local drives for the specified number of times before failing on Windows systems.
# network redirector: Report DOS network redirector as resident. This will allow the host name to be returned unless the secure mode is enabled.
# Set either "ipx=true" in [ipx] section or "ne2000=true" in [ne2000] section for a full network redirector environment.
# minimum dos initial private segment: In non-mainline mapping mode, where DOS structures are allocated from base memory, this sets the
# minimum segment value. Recommended value is 0x70. You may reduce the value down to 0x50 if freeing
# up more memory is important. Set to 0 for default.
# minimum mcb segment: Minimum segment value to begin memory allocation from, in hexadecimal. Set to 0 for default.
# You can increase available DOS memory by reducing this value down to as low as 0x51, however
# setting it to low can cause some DOS programs to crash or run erratically, and some DOS games
# and demos to cause intermittent static noises when using Sound Blaster output. DOS programs
# compressed with Microsoft EXEPACK will not run if the minimum MCB segment is below 64KB. This differs
# from 'minimum mcb free' in that this affects the starting point of the mcb chain instead of the lowest free block.
# minimum mcb free: Minimum free segment value to leave free. At startup, the DOS kernel will allocate memory
# up to this point. This can be used to deal with EXEPACK issues or DOS programs that cannot
# be loaded too low in memory. If you want more free conventional memory to be reported,
# you can for example set its value to 1.
# enable dummy device mcb: If set (default), allocate a fake device MCB at the base of conventional memory.
# Clearing this option can reclaim a small amount of conventional memory at the expense of
# some minor DOS compatibility.
# maximum environment block size on exec: Maximum environment block size to copy for child processes. Set to -1 for default.
# additional environment block size on exec: When executing a program, compute the size of the parent block then add this amount to allow for a few additional variables.
# If the subprocesses will never add/modify the environment block, you can free up a few additional bytes by setting this to 0.
# Set to -1 for default setting.
# enable a20 on windows init: If set, DOSBox-X will enable the A20 gate when Windows 3.1/9x broadcasts the INIT message
# at startup. Windows 3.1 appears to make assumptions at some key points on startup about
# A20 that don't quite hold up and cause Windows 3.1 to crash when you set A20 emulation
# to a20=mask as opposed to a20=fast. This option is enabled by default.
# zero memory on xms memory allocation: If set, memory returned by XMS allocation call is zeroed first. This is NOT what
# DOS actually does, but if set, can help certain DOS games and demos cope with problems
# related to uninitialized variables in extended memory. When enabled this option may
# incur a slight to moderate performance penalty.
# dosv: Enable DOS/V emulation and specify which version to emulate. This option is intended for
# use with games or software originating from Asia that use the double byte character set
# encodings and the DOS/V extensions to display Japanese, Chinese, or Korean text.
# Note that enabling DOS/V replaces 80x25 text mode (INT 10h mode 3) with a EGA/VGA graphics
# mode that emulates text mode to display the characters and may be incompatible with non-Asian
# software that assumes direct access to the text mode via segment 0xB800.
# WARNING: This option is very experimental at this time.
# Possible values: off, japanese, chinese, korean.
# ems: Enable EMS support. The default (=true) provides the best
# compatibility but certain applications may run better with
# other choices, or require EMS support to be disabled (=false)
# to work at all.
# Possible values: true, emsboard, emm386, false, 1, 0.
# vcpi: If set and expanded memory is enabled, also emulate VCPI.
# unmask timer on disk io: If set, INT 21h emulation will unmask IRQ 0 (timer interrupt) when the application opens/closes/reads/writes files.
# zero int 67h if no ems: If ems=false, leave interrupt vector 67h zeroed out (default true).
# This is a workaround for games or demos that try to detect EMS by whether or not INT 67h is 0000:0000 rather than a proper test.
# This option also affects whether INT 67h is zeroed when booting a guest OS.
# zero unused int 68h: Leave INT 68h zero at startup.
# Set this to true for certain games that use INT 68h in unusual ways that require a zero value.
# Note that the vector is left at zero anyway when machine=cga.
# This is needed to properly run 1988 game 'PopCorn'.
# emm386 startup active: If set and expanded memory is set to emulate emm386, start the DOS machine with EMM386.EXE active
# (running the 16-bit DOS environment from within Virtual 8086 mode). If you will be running anything
# that involves a DOS extender you will also need to enable the VCPI interface as well.
# zero memory on ems memory allocation: If set, memory returned by EMS allocation call is zeroed first. This is NOT what
# DOS actually does, but if set, can help certain DOS games and demos cope with problems
# related to uninitialized variables in expanded memory. When enabled this option may
# incur a slight to moderate performance penalty.
# ems system handle memory size: Amount of memory associated with system handle, in KB.
# ems system handle on even megabyte: If set, try to allocate the EMM system handle on an even megabyte.
# If the DOS game or demo fiddles with the A20 gate while using EMM386.EXE emulation in virtual 8086 mode, setting this option may help prevent crashes.
# However, forcing allocation on an even megabyte will also cause some extended memory fragmentation and reduce the
# overall amount of extended memory available to the DOS game depending on whether it expects large contiguous chunks
# of extended memory.
# umb: Enable UMB support.
# umb start: UMB region starting segment
# umb end: UMB region last segment
# kernel allocation in umb: If set, dynamic kernel allocation=1, and private area in umb=1, all kernel structures will be allocated from the private area in UMB.
# If you intend to run Windows 3.1 in DOSBox-X, you must set this option to false else Windows 3.1 will not start.
# keep umb on boot: If emulating UMBs, keep the UMB around after boot (Mainline DOSBox behavior). If clear, UMB is unmapped when you boot an operating system.
# keep private area on boot: If set, keep the DOSBox-X private area around after boot (Mainline DOSBox behavior). If clear, unmap and discard the private area when you boot an operating system.
# Possible values: true, false, 1, 0, auto.
# private area in umb: If set, keep private DOS segment in upper memory block, usually segment 0xC800 (Mainline DOSBox behavior)
# If clear, place private DOS segment at the base of system memory (just below the MCB)
# quick reboot: If set, the DOS restart call will reboot the emulated DOS (integrated DOS or guest DOS) instead of the virtual machine.
#
# ver: Set DOS version. Specify as major.minor format. A single number is treated as the major version (compatible with LFN support). Common settings are:
# auto (or unset) Pick a DOS kernel version automatically
# 3.3 MS-DOS 3.3 emulation (not tested!)
# 5.0 MS-DOS 5.0 emulation (recommended for DOS gaming)
# 6.22 MS-DOS 6.22 emulation
# 7.0 MS-DOS 7.0 (or Windows 95 pure DOS mode) emulation
# 7.1 MS-DOS 7.1 (or Windows 98 pure DOS mode) emulation
# Long filename (LFN) support will be enabled with a reported DOS version of 7.0 or higher with "lfn=auto" (default).
# Similarly, FAT32 disk images will be supported with a reported DOS version of 7.1 or higher.
#
# lfn: Enable long filename support. If set to auto (default), it is enabled if the reported DOS version is at least 7.0.
# If set to autostart, the builtin VER command won't activate/disactivate LFN support according to the reported DOS version.
# Possible values: true, false, 1, 0, auto, autostart.
# automount: Enable automatic drive mounting in Windows.
# automountall: Automatically mount all available Windows drives at start.
# mountwarning: If set, a warning will be displayed if you try to mount C:\ in Windows or / in other platforms.
# autoa20fix: If set (default), DOSBox-X will automatically re-run the executable with the A20 gate disabled if it failed with the "Packed file is corrupt" error.
# If both autoa20fix and autoloadfix are set, then the former will be tried first, and the latter will be tried if the former did not work.
# autoloadfix: If set (default), DOSBox-X will automatically re-run the executable with LOADFIX if it failed with the "Packed file is corrupt" error.
# autofixwarning: If set to true or both, DOSBox-X will show messages when trying to automatically fix the "Packed file is corrupt" error.
# If set to false or none, DOSBox-X will not show such messages on the screen when the error occurred.
# If set to "a20fix" or "loadfix", DOSBox-X will show the message for the a20fix or the loadfix only.
# Possible values: true, false, 1, 0, both, a20fix, loadfix, none.
# startcmd: Allow starting Windows programs or commands to run on the Windows host including the use of START command.
# startwait: Specify whether DOSBox-X should wait for the Windows applications after they are started.
# startquiet: If set, before launching Windows applications to run on the host DOSBox-X will not show messages like "Now run it as a Windows application".
# startincon: START command will start these commands (separated by space) in a console and wait for a key press before exiting.
# int33: Enable INT 33H for mouse support.
# int33 hide host cursor if interrupt subroutine: If set, the cursor on the host will be hidden if the DOS application provides it's own
# interrupt subroutine for the mouse driver to call, which is usually an indication that
# the DOS game wishes to draw the cursor with it's own support routines (DeluxePaint II).
# int33 hide host cursor when polling: If set, the cursor on the host will be hidden even if the DOS application has also
# hidden the cursor in the guest, as long as the DOS application is polling position
# and button status. This can be useful for DOS programs that draw the cursor on their
# own instead of using the mouse driver, including most games and DeluxePaint II.
# int33 disable cell granularity: If set, the mouse pointer position is reported at full precision (as if 640x200 coordinates) in all modes.
# If not set, the mouse pointer position is rounded to the top-left corner of a character cell in text modes.
# This option is OFF by default.
# int 13 extensions: Enable INT 13h extensions (functions 0x40-0x48). You will need this enabled if the virtual hard drive image is 8.4GB or larger.
# biosps2: Emulate BIOS INT 15h PS/2 mouse services
# Note that some OS's like Microsoft Windows neither use INT 33h nor
# probe the AUX port directly and depend on this BIOS interface exclusively
# for PS/2 mouse support. In other cases there is no harm in leaving this enabled
# int15 wait force unmask irq: Some demos or games mistakingly use INT 15h AH=0x86 (WAIT) while leaving the IRQs needed for it masked.
# If this option is set (by default), the necessary IRQs will be unmasked when INT 15 AH=0x86 is used so that the game or demo does not hang.
# int15 mouse callback does not preserve registers: Set to true if the guest OS or DOS program assigns an INT 15h mouse callback,
# but does not properly preserve CPU registers. Diagnostic function only (default off).
# keyboardlayout: Language code of the keyboard layout (or none).
# dbcs: Enable DBCS table.
# CAUTION: Some software will crash without the DBCS table, including the Open Watcom installer.
#
# filenamechar: Enable filename char table
# collating and uppercase: Enable collating and uppercase table
# con device use int 16h to detect keyboard input: If set, use INT 16h to detect keyboard input (MS-DOS 6.22 behavior). If clear, detect keyboard input by
# peeking into the BIOS keyboard buffer (Mainline DOSBox behavior). You will need to set this
# option for programs that hook INT 16h to handle keyboard input ahead of the DOS console.
# Microsoft Scandisk needs this option to respond to keyboard input correctly.
# zero memory on int 21h memory allocation: If set, memory returned by the INT 21h allocation call is zeroed first. This is NOT what
# DOS actually does, but if set, can help certain DOS games and demos cope with problems
# related to uninitialized variables in the data or stack segment. If you intend to run a
# game or demo known to have this problem (Second Unreal, for example), set to true, else
# set to false. When enabled this option may incur a slight to moderate performance penalty.
# dos clipboard device enable: If enabled, a DOS device will be added for bidirectional communications with the shared clipboard.
# Setting to "read" will only allow read access, and setting to "write" will only allow write access.
# Setting to "full" or "true" enables both; setting to "false" or "disabled" disables the access or device.
# The default device name is CLIP$, but can be changed with the "dos clipboard device name" setting below.
# dos clipboard device name: Set DOS device name (up to 8 characters) for bidirectional communications with the shared clipboard.
# If unset or invalid, the default name CLIP$ will be used (e.g. "TYPE CLIP$" shows the clipboard contents).
# It has no effect if "dos clipboard device enable" is disabled, and it is deactivated if the secure mode is enabled.
# dos clipboard api: If set, DOS APIs for communications with the Windows clipboard will be enabled for shared clipboard communications.

# pnp: List floppy controller in ISA PnP BIOS enumeration
# irq: IRQ used by floppy controller. Set to 0 for default.
# WARNING: Setting the IRQ to non-standard values will not work unless the guest OS is using the ISA PnP BIOS to detect the floppy controller.
# Setting the IRQ to one already occupied by another device or IDE controller will trigger "resource conflict" errors in Windows 95.
# Normally, floppy controllers use IRQ 6.
# io: Base I/O port for floppy controller. Set to 0 for default.
# WARNING: Setting the I/O port to non-standard values will not work unless the guest OS is using the ISA PnP BIOS to detect the IDE controller.
# Standard I/O ports are 3F0 and 370.
# dma: DMA channel for floppy controller. Set to -1 for default.
# WARNING: Setting the DMA channel to non-standard values will not work unless the guest OS is using the ISA PnP BIOS to detect the IDE controller.
# Standard DMA channel is 2.
# int13fakev86io: If set, certain INT 13h commands will cause floppy emulation to issue fake CPU I/O
# traps (GPF) in virtual 8086 mode and a fake IRQ signal. You must enable this
# option if you want 32-bit floppy access in Windows 95 to work with DOSBox-X.
# instant mode: If set, all floppy operations are 'instantaneous', they are carried
# out without any delay. Real hardware of course has motor, command
# and data I/O delays and so this option is off by default for realistic
# emulation.
# auto-attach to int 13h: If set, DOSBox-X will automatically attach a disk image as being
# inserted into a floppy drive attached to the controller when imgmount is used
# to mount a disk image to drive 0/1 or A/B. If not set, you must specify
# the -fdc option to imgmount to attach drive A/B to the floppy controller
# manually. You must use the -fdc option regardless if loading floppies into
# drives attached to any other FDC than the primary controller
# mode: Floppy controller mode. What the controller acts like.
# ps2 PS/2 mode (most common)
# ps2_model30 PS/2 model 30
# at AT mode
# xt PC/XT mode
# chip: Floppy controller chipset
# 82077aa Intel 82077AA chipset
# 82072 Intel 82072 chipset
# nec_uPD765 NEC uPD765 chipset
# none No chipset (For PC/XT mode)
