dosbox-staging.conf
# This is the configuration file for dosbox-staging (0.81.0-alpha).
# Lines starting with a '#' character are comments.
[sdl]
# fullscreen: Start directly in fullscreen (disabled by default).
# Run INTRO and see Special Keys for window control hotkeys.
# display: Number of display to use; values depend on OS and user settings (0 by default).
# fullresolution: What resolution to use for fullscreen: 'original', 'desktop'
# or a fixed size, e.g. 1024x768 ('desktop' by default).
# windowresolution: Set window size when running in windowed mode:
# default: Select the best option based on your environment and
# other settings.
# small, medium, large (s, m, l):
# Size the window relative to the desktop.
# <custom>: Scale the window to the given dimensions in WxH format.
# For example: 1024x768.
# viewport_resolution: Set the viewport size (drawable area) within the window/screen:
# fit: Fit the viewport to the available window/screen (default).
# <custom>: Limit the viewport within to a custom resolution or percentage of
# the desktop. Specified in WxH, N%, N.M%. Examples: 960x720 or 50%
# window_position: Set initial window position when running in windowed mode:
# auto: Let the window manager decide the position (default).
# <custom>: Set window position in X,Y format. For example: 250,100
# 0,0 is the top-left corner of the screen.
# window_decorations: Enable window decorations in windowed mode (enabled by default).
# transparency: Set the transparency of the DOSBox Staging screen (0 by default).
# From 0 (no transparency) to 90 (high transparency).
# host_rate: Set the host's refresh rate:
# auto: Use SDI rates, or VRR rates when fullscreen on a high-refresh
# display (default).
# sdi: Use serial device interface (SDI) rates, without further
# adjustment.
# vrr: Deduct 3 Hz from the reported rate (best practice for VRR
# displays).
# <custom>: Specify a custom rate as an integer or decimal Hz value
# (23.000 is the allowed minimum).
# vsync: Set the host video driver's vertical synchronization (vsync) mode:
# auto: Limit vsync to beneficial cases, such as when using an
# interpolating VRR display in fullscreen (default).
# on: Enable vsync. This can prevent tearing in some games but will
# impact performance or drop frames when the DOS rate exceeds the
# host rate (e.g. 70 Hz DOS rate vs 60 Hz host rate).
# adaptive: Enables vsync when the frame rate is higher than the host rate,
# but disables it when the frame rate drops below the host rate.
# Note: only valid in OpenGL output modes; otherwise treated as 'on'.
# off: Attempt to disable vsync to allow quicker frame presentation at
# the risk of tearing in some games.
# yield: Let the host's video driver control video synchronization.
# Possible values: auto, on, adaptive, off, yield.
# vsync_skip: Number of microseconds to allow rendering to block before skipping the
# next frame. For example, a value of 7000 is roughly half the frame time
# at 70 Hz. 0 disables this and will always render (default).
# presentation_mode: Select the frame presentation mode:
# auto: Intelligently time and drop frames to prevent emulation stalls,
# based on host and DOS frame rates (default).
# cfr: Always present DOS frames at a constant frame rate.
# vfr: Always present changed DOS frames at a variable frame rate.
# Possible values: auto, cfr, vfr.
# output: Video system to use for output ('opengl' by default).
# 'texture' and 'opengl' use bilinear interpolation, 'texturenb' and
# 'openglnb' use nearest-neighbour (no-bilinear). Some shaders require
# bilinear interpolation, making that the safest choice.
# Possible values: texture, texturenb, opengl, openglnb.
# Deprecated values: openglpp, surface, texturepp.
# texture_renderer: Render driver to use in 'texture' output mode ('auto' by default).
# Use 'texture_renderer = auto' for an automatic choice.
# Possible values: auto, opengl, opengles2, software.
# waitonerror: Keep the console open if an error has occurred (enabled by default).
# priority: Priority levels to apply when active and inactive, respectively.
# ('auto auto' by default)
# 'auto' lets the host operating system manage the priority.
# Possible values: auto, lowest, lower, normal, higher, highest.
# mute_when_inactive: Mute the sound when the window is inactive (disabled by default).
# pause_when_inactive: Pause emulation when the window is inactive (disabled by default).
# mapperfile: File used to load/save the key/event mappings.
# Pre-configured maps are bundled in the 'resources/mapperfiles' directory.
# They can be loaded by name, for example: mapperfile = xbox/xenon2.map
# Note: The --resetmapper command line flag only deletes the default mapperfile.
# screensaver: Use 'allow' or 'block' to override the SDL_VIDEO_ALLOW_SCREENSAVER environment
# variable which usually blocks the OS screensaver while the emulator is
# running ('auto' by default).
# Possible values: auto, allow, block.

# (unset by default; this defaults to English)
# Notes:
# - This setting will override the 'LANG' environment variable, if set.

# feature.
# machine: Set the video adapter or machine to emulate:
# hercules: Hercules Graphics Card (HGC) (see 'monochrome_palette').
# cga_mono: CGA adapter connected to a monochrome monitor (see
# 'monochrome_palette').

# video emulation (see [composite] section).
# pcjr: An IBM PCjr machine. Also enables PCjr sound and composite
# video emulation (see [composite] section).
# tandy: A Tandy 1000 machine with TGA graphics. Also enables Tandy
# sound and composite video emulation (see [composite]
# section).
# ega: IBM Enhanced Graphics Adapter (EGA).
# svga_paradise: Paradise PVGA1A SVGA card (no VESA VBE; 512K vmem by default,
# can be set to 256K or 1MB with 'vmemsize'). This is the
# closest to IBM's original VGA adapter.
# svga_et3000: Tseng Labs ET3000 SVGA card (no VESA VBE; fixed 512K vmem).
# svga_et4000: Tseng Labs ET4000 SVGA card (no VESA VBE; 1MB vmem by

# svga_s3: S3 Trio64 (VESA VBE 2.0; 4MB vmem by default, can be set to
# 512K, 1MB, 2MB, or 8MB with 'vmemsize') (default)
# vesa_oldvbe: Same as 'svga_s3' but limited to VESA VBE 1.2.
# vesa_nolfb: Same as 'svga_s3' (VESA VBE 2.0), plus the "no linear
# framebuffer" hack (needed only by a few games).
# Possible values: hercules, cga_mono, cga, pcjr, tandy, ega, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe.
# Deprecated values: vgaonly.
# memsize: Amount of memory of the emulated machine has in MB (16 by default).
# Best leave at the default setting to avoid problems with some games,
# though a few games might require a higher value.
# There is generally no speed advantage when raising this value.
# mcb_fault_strategy: How software-corrupted memory chain blocks should be handled:
# repair: Repair (and report) faults using adjacent blocks (default).
# report: Report faults but otherwise proceed as-is.
# allow: Allow faults to go unreported (hardware behavior).
# deny: Quit (and report) when faults are detected.
# Possible values: repair, report, allow, deny.
# vmemsize: Video memory in MB (1-8) or KB (256 to 8192). 'auto' uses the default for
# the selected video adapter ('auto' by default). See the 'machine' setting for
# the list of valid options per adapter.
# Possible values: auto, 1, 2, 4, 8, 256, 512, 1024, 2048, 4096, 8192.
# dos_rate: Customize the emulated video mode's frame rate, in Hz:
# default: The DOS video mode determines the rate (recommended; default).
# host: Match the DOS rate to the host rate (see 'host_rate' setting).
# <value>: Sets the rate to an exact value, between 24.000 and 1000.000 (Hz).
# We recommend the 'default' rate; otherwise test and set on a per-game basis.
# vesa_modes: Controls the selection of VESA 1.2 and 2.0 modes offered:
# compatible: A tailored selection that maximizes game compatibility.
# This is recommended along with 4 or 8 MB of video memory
# (default).
# halfline: Supports the low-resolution halfline VESA 2.0 mode used by
# Extreme Assault. Use only if needed, as it's not S3 compatible.
# all: All modes for a given video memory size, however some games
# may not use them properly (flickering) or may need
# more system memory to use them.
# Possible values: compatible, all, halfline.
# vga_8dot_font: Use 8-pixel-wide fonts on VGA adapters (disabled by default).
# speed_mods: Permit changes known to improve performance (enabled by default).
# Currently, no games are known to be negatively affected by this.
# Please file a bug with the project if you find a game that fails
# when this is enabled so we will list them here.
# autoexec_section: How autoexec sections are handled from multiple config files:
# join: Combine them into one big section (legacy behavior; default).
# overwrite: Use the last one encountered, like other config settings.
# Possible values: join, overwrite.
# automount: Mount 'drives/[c]' directories as drives on startup, where [c] is a lower-case
# drive letter from 'a' to 'y' (enabled by default). The 'drives' folder can be
# provided relative to the current directory or via built-in resources.
# Mount settings can be optionally provided using a [c].conf file along-side
# the drive's directory, with content as follows:
# [drive]
# type = dir, overlay, floppy, or cdrom
# label = custom_label
# path = path-specification, ie: path = %%path%%;c:\tools
# override_drive = mount the directory to this drive instead (default empty)
# verbose = true or false
# startup_verbosity: Controls verbosity prior to displaying the program ('auto' by default):
# Verbosity | Welcome | Early stdout
# high | yes | yes
# low | no | yes
# quiet | no | no
# auto | 'low' if exec or dir is passed, otherwise 'high'
# Possible values: auto, high, low, quiet.
# allow_write_protected_files: Many games open all their files with writable permissions; even files that they
# never modify. This setting lets you write-protect those files while still
# allowing the game to read them. A second use-case: if you're using a
# copy-on-write or network-based filesystem, this setting avoids triggering
# write-operations for these write-protected files.
# shell_config_shortcuts: Allow shortcuts for direct configuration management (enabled by default), i.e.
# instead of 'config -set sbtype sb16' it is enough to execute 'sbtype sb16',
# and instead of 'config -get sbtype' it is enough to execute 'sbtype' command.

# aspect: Apply aspect ratio correction for modern square-pixel flat-screen displays,
# so DOS resolutions with non-square pixels appear as they would on a 4:3 display
# aspect ratio CRT monitor the majority of DOS games were designed for (enabled
# by default). This setting only affects video modes that use non-square pixels,
# such as 320x200 or 640x400; square-pixel modes, such as 320x240, 640x480, and
# 800x600 are displayed as-is.
# integer_scaling: Constrain the horizontal or vertical scaling factor to integer values.
# The correct aspect ratio is always maintained according to the 'aspect'
# setting, which may result in a non-integer scaling factor in the other
# direction. If the image is larger than the viewport, the integer scaling
# constraint is auto-disabled (same as 'off'). Possible values:
# auto: 'vertical' mode auto-enabled for adaptive CRT shaders only,
# otherwise 'off' (default).
# vertical: Constrain the vertical scaling factor to integer values within
# the viewport. This is the recommended setting when using CRT
# shaders to avoid uneven scanlines and unwanted interference
# artifacts.
# horizontal: Constrain the horizontal scaling factor to integer values within
# the viewport.
# off: No integer scaling constraint is applied; the image fills the
# viewport according to the 'aspect' setting.
# Possible values: auto, vertical, horizontal, off.
# monochrome_palette: Set the palette for monochrome display emulation ('amber' by default).
# Works only with the 'hercules' and 'cga_mono' machine types.
# Note: You can also cycle through the available palettes via hotkeys.
# Possible values: amber, green, white, paperwhite.
# cga_colors: Set the interpretation of CGA RGBI colours. Affects all machine types capable
# of displaying CGA or better graphics. Built-in presets:
# default: The canonical CGA palette, as emulated by VGA adapters
# (default).
# tandy <bl>: Emulation of an idealised Tandy monitor with adjustable brown
# level. The brown level can be provided as an optional second
# parameter (0 - red, 50 - brown, 100 - dark yellow;
# defaults to 50). E.g. tandy 100
# tandy-warm: Emulation of the actual colour output of an unknown Tandy
# monitor.
# ibm5153 <c>: Emulation of the actual colour output of an IBM 5153 monitor
# with a unique contrast control that dims non-bright colours
# only. The contrast can be optionally provided as a second
# parameter (0 to 100; defaults to 100), e.g. ibm5153 60
# agi-amiga-v1, agi-amiga-v2, agi-amiga-v3:
# Palettes used by the Amiga ports of Sierra AGI games.
# agi-amigaish: A mix of EGA and Amiga colours used by the Sarien
# AGI-interpreter.
# scumm-amiga: Palette used by the Amiga ports of LucasArts EGA games.
# colodore: Commodore 64 inspired colours based on the Colodore palette.
# colodore-sat: Colodore palette with 20% more saturation.
# dga16: A modern take on the canonical CGA palette with dialed back
# contrast.
# You can also set custom colours by specifying 16 space or comma separated
# colour values, either as 3 or 6-digit hex codes (e.g. #f00 or #ff0000 for full
# red), or decimal RGB triplets (e.g. (255, 0, 255) for magenta). The 16 colours
# are ordered as follows:
# black, blue, green, cyan, red, magenta, brown, light-grey, dark-grey,
# light-blue, light-green, light-cyan, light-red, light-magenta, yellow, white.
# Their default values, shown here in 6-digit hex code format, are:
# #000000 #0000aa #00aa00 #00aaaa #aa0000 #aa00aa #aa5500 #aaaaaa
# #555555 #5555ff #55ff55 #55ffff #ff5555 #ff55ff #ffff55 #ffffff
# glshader: Set an adaptive CRT monitor emulation shader or a regular GLSL shader in OpenGL
# output modes.
# Adaptive CRT shader options:
# crt-auto: A CRT shader that prioritises developer intent and how
# people experienced the game at the time of release
# (default). The appropriate shader variant is
# automatically selected based the graphics standard of
# the current video mode and the viewport resolution,
# irrespective of the 'machine' setting. This means that
# even on an emulated VGA card you'll get authentic
# single-scanned EGA monitor emulation with visible
# "thick scanlines" in EGA games.
# crt-auto-machine: Similar to 'crt-auto', but this picks a fixed CRT
# monitor appropriate for the video adapter configured
# via the 'machine' setting. E.g., CGA and EGA games
# will appear double-scanned on an emulated VGA
# adapter.
# crt-auto-arcade: Emulation of an arcade or home computer monitor less
# sharp than a typical PC monitor with thick scanlines
# in low-resolution modes. This fantasy option does not
# exist in real life, but it can be a lot of fun,
# especially with DOS ports of Amiga games.
# crt-auto-arcade-sharp: A sharper variant of the arcade shader for those who
# like the thick scanlines but want to retain the
# horizontal sharpness of a typical PC monitor.
# Other options include 'sharp', 'none', a shader listed using the
# --list-glshaders command-line argument, or an absolute or relative path
# to a file. In all cases, you may omit the shader's '.glsl' file extension.

[composite]
# composite: Enable composite mode on start ('auto' by default).

# then read the new settings from your console and enter them here.
# Possible values: auto, on, off.
# era: Era of composite technology ('auto' by default).
# When 'auto', PCjr uses 'new', and CGA/Tandy use 'old'.

# integer vertically). The filenames of upscaled screenshots
# have no postfix (e.g. 'image0001.png').
# rendered: The post-rendered, post-shader image shown on the screen is
# captured. The filenames of rendered screenshots end with
# '-rendered' (e.g. 'image0001-rendered.png').
# raw: The contents of the raw framebuffer is captured (this always
# results in square pixels). The filenames of raw screenshots
# end with '-raw' (e.g. 'image0001-raw.png').

# on some host operating systems.
# seamless: Let the mouse move seamlessly between the DOSBox window and the
# rest of the desktop; captures only with middle-click or hotkey.
# Seamless mouse does not work correctly with all the games.
# Windows 3.1x can be made compatible with a custom mouse driver.
# nomouse: Hide the mouse and don't send mouse input to the game.
# For touch-screen control, use 'seamless'.
# Possible values: seamless, onclick, onstart, nomouse.
# mouse_middle_release: If enabled, middle-click will release the captured mouse, and also capture
# when seamless (enabled by default).
# mouse_multi_display_aware: Allows mouse seamless behavior and mouse pointer release to work in fullscreen
# mode for systems with more than one display. (enabled by default).
# Note: You should disable this if it incorrectly detects multiple displays
# when only one should actually be used. This might happen if you are
# using mirrored display mode or using an AV receiver's HDMI input for
# audio-only listening.
# mouse_sensitivity: Mouse sensitivity for the horizontal and vertical axes, as a percentage
# (100,100 by default). Negative values invert the axis, zero disables it.
# Providing only one value sets sensitivity for both axes.
# The setting can be adjusted in runtime (also per mouse interface) using
# internal MOUSECTL.COM tool, available on drive Z.
# mouse_raw_input: Enable to bypass your operating system's mouse acceleration and sensitivity
# settings (enabled by default). Works in fullscreen or when the mouse is
# captured in window mode.
# dos_mouse_driver: Enable built-in DOS mouse driver (enabled by default).
# Notes:
# - Disable if you intend to use original MOUSE.COM driver in emulated DOS.
# - When guest OS is booted, built-in driver gets disabled automatically.
# dos_mouse_immediate: Update mouse movement counters immediately, without waiting for interrupt
# (disabled by default). May improve gameplay, especially in fast-paced games
# (arcade, FPS, etc.), as for some games it effectively boosts the mouse
# sampling rate to 1000 Hz, without increasing interrupt overhead.
# Might cause compatibility issues. List of known incompatible games:
# - Ultima Underworld: The Stygian Abyss
# - Ultima Underworld II: Labyrinth of Worlds
# Please report it if you find another incompatible game so we can update this

# mididevice: Set where MIDI data from the emulated MPU-401 MIDI interface is sent

# oss: Use the Linux OSS MIDI playback interface.
# alsa: Use the Linux ALSA MIDI playback interface.
# fluidsynth: The built-in FluidSynth MIDI synthesizer (SoundFont player).
# See the [fluidsynth] section for detailed configuration.
# mt32: The built-in Roland MT-32 synthesizer.
# See the [mt32] section for detailed configuration.
# auto: Either one of the built-in MIDI synthesisers (if `midiconfig` is
# set to 'fluidsynth' or 'mt32'), or a MIDI device external to
# DOSBox (any other 'midiconfig' value). This might be a software
# synthesizer or physical device. This is the default behaviour.
# none: Disable MIDI output.
# Possible values: auto, oss, alsa, fluidsynth, mt32, none.
# midiconfig: Configuration options for the selected MIDI interface (unset by default).
# This is usually the ID or name of the MIDI synthesizer you want
# to use (find the ID/name with the DOS command 'MIXER /LISTMIDI').
# Notes:
# - This option has no effect when using the built-in synthesizers
# ('mididevice = fluidsynth' or 'mididevice = mt32').
# - When using ALSA, use the Linux command 'aconnect -l' to list all open
# MIDI ports and select one (e.g. 'midiconfig = 14:0' for sequencer
# client 14, port 0).
# - If you're using a physical Roland MT-32 with revision 0 PCB, the hardware
# may require a delay in order to prevent its buffer from overflowing.
# In that case, add 'delaysysex' (e.g. 'midiconfig = 2 delaysysex').
# mpu401: MPU-401 mode to emulate ('intelligent' by default).
# Possible values: intelligent, uart, none.
# raw_midi_output: Enable raw, unaltered MIDI output (disabled by default).
# The MIDI drivers of many games don't fully conform to the MIDI standard,
# which makes editing the MIDI recordings of these games very error-prone and
# cumbersome in MIDI sequencers, often resulting in hanging or missing notes.
# DOSBox corrects the MIDI output of such games by default. This results in no
# audible difference whatsoever; it only affects the representation of the MIDI
# data. You should only enable 'raw_midi_output' if you really need to capture
# the raw, unaltered MIDI output of a program, e.g. when working with music
# applications, or when debugging MIDI issues.

# An optional percentage value after the name will scale the SoundFont's volume.
# This is useful for normalising the volume of different SoundFonts.
# E.g. 'my_soundfont.sf2 50' will attenuate the volume by 50%.
# The percentage value can range from 1 to 800.
# fsynth_chorus: Chorus effect: 'auto' (default), 'on', 'off', or custom values.
# When using custom values:
# All five must be provided in-order and space-separated.

# - voice-count is an integer from 0 to 99.
# - level is a decimal from 0.0 to 10.0
# - speed is a decimal, measured in Hz, from 0.1 to 5.0
# - depth is a decimal from 0.0 to 21.0
# - modulation-wave is either 'sine' or 'triangle'
# For example: chorus = 3 1.2 0.3 8.0 sine
# Note: You can disable the FluidSynth chorus and enable the mixer-level chorus
# on the FluidSynth channel instead, or enable both chorus effects at the
# same time. Whether this sounds good depends on the SoundFont and the
# chorus settings being used.
# fsynth_reverb: Reverb effect: 'auto' (default), 'on', 'off', or custom values.
# When using custom values:
# All four must be provided in-order and space-separated.
# They are: room-size damping width level, where:
# - room-size is a decimal from 0.0 to 1.0
# - damping is a decimal from 0.0 to 1.0
# - width is a decimal from 0.0 to 100.0
# - level is a decimal from 0.0 to 1.0
# For example: reverb = 0.61 0.23 0.76 0.56
# Note: You can disable the FluidSynth reverb and enable the mixer-level reverb
# on the FluidSynth channel instead, or enable both reverb effects at the
# same time. Whether this sounds good depends on the SoundFont and the
