My crap incomplete notes for the Into the Shadows demo from 1995 - rest of this is an executable that scans through the demo searching for crap
The packed EXE ends at 175869 bytes into the file
20 is ' '
0A is '\n'
0D is '\r'
TVR procedure texture definition file
This is declared 2406022 bytes in
Possibly 254 bytes? - unable to find any clues
There's another application entry at OFFSET BC292 (770706)
Also appears to be compressed, it's exactly the same size too
Ends at 946575 bytes in
Applications might be decompressor for actual main executables?
And very possibly, both of these executables are possibly the same... (one is older version?)
7b91849c1eb382d8bcd6b6df37b7ebd4 ./TSUPTMP0_A.EXE (first executable, the one we usually run)
fd2ee0a985a02783adc5b159a1b346a1 ./TSUPTMP0.$$$ (second executable, this one will crash on launch)

Some guesstimates to the game's little script that's used
for laying out the intro sequence and how each of the 'functions'
operate for the demo...
setuseobj ,<obj>,<?>,<?> doesn't appear to actually do anything
setobjpos ,<obj>,<x>,<y>,<z>
setobjrot ,<obj>,<?>,<?>,<?>
setvrobjflags ,<obj>,<flag>
setaimobj ,<obj>,<obj_targ>,<?>,<?>,<?>,<?>
setobjrotaim ,<obj>,<obj_targ>,<?>,<?>,<?>
playanim ,<obj>,<flag>,<animation>,<speed>,<?>
obj 0 = Erik
obj 1 = Zombie #1
obj 2 = Zombie #2
obj 3 = Skeleton
obj 5 = Orc
obj 6 = ?
obj 7 = ?
obj 8 = ?
obj 9 = ?
obj 10 = camera
flag 43 = possibly hides the object?
flag 63 = possibly shows the object?
Further testing leads me to think these have more to do with
how the objects are simulated in the game
Just confirmed the above!
; Visible = $0020; { Ej visible => Ej Hitable }
; Vector = $0040;
Objects 6 and 7 are never ever displayed in the demo as far as I can tell
I've changed their flags to 63 on init - couldn't see anything different :(
Set obj 6 and 7 to position at the start of the demo, nothing is rendered though...
Bummer.

VR System File Format
Header appears to be uniformly 50 bytes for
each file - regardless of type?
Each file is made up of a number of blocks
at the start.
Here's a rough very layout of the format...
Header
char heading[50]
uint8_t version (26 for everything)
Chunk Header
uint8_t desc_length
char desc[desc_length]
Each chunk is then followed by the data for
that particular chunk - if the chunk is not a
fixed size then it is followed by an unsigned
16-bit integer
_______________________________________________
VR-System construction
Seems to use the following descriptors for chunks,
which all seem to be fixed length?
PROJECT (2 bytes long)
char name[2]
ROOMBSP (2 bytes long, there's one for each LEVEL)
uint16_t unknown
N-ROOMS (20 bytes long, possibly relative to number of ROOMBSP entries)
uint16_t unknown[number of BSP rooms]
ROOMLST (96 bytes long)
seems to link in with visibility and the lightmap
blanking this whole section seems to result in the
main section of the level appearing fully-lit
PACKCRD (2 bytes long)
appears to do nothing
UNPACKC (2 bytes long)
appears to do nothing
SRTWALL
uint16_t length
24 (changing this stopped the game from loading)
84 (something to do with the way sectors / walls are dealt with... very fragile, but interesting results!)
00 (unsure, nothing obvious)
AC21 (seems to do multiple things - stopped some textures being applied and fucked up drawing order)
0C (changing this gives a general protection fault)
00 (changing this stopped the game from loading)
A4 (changing this gives a general protection fault)
11 (changing this stopped the game from loading)
00 (unsure, nothing obvious)
28 (unsure, nothing obvious)
0100 (something to do with the way sectors / walls are dealt with)
18 (something to do with textures)
002800100088046400900492046C006E00FFFF1D4090043000F0DF3F183F1800000000
CELLPCK (packed data?)
uint16_t length
the rest of it seems to do nothing
BMPWALL (2 bytes long)
appears to do nothing
BSPTREE (4 bytes long)
appears to do nothing
LEVEL 0 (increments for each 'BSPTREE' segment)
LEVEL 1
LEVEL 2

LEVEL 4
LEVEL 5
LEVEL 6
LEVEL 7
LEVEL 8
LEVEL 9 @ 14F070
FLRMAPS @ 151090
uint16_t num_floors
(each floor / tile is 14 bytes, so 14 * num_floors)
Floor
uint16_t index ?
uint32_t unknown
[0000] some sort of index

_______________________________________________
The contents of the demo build seem to be typically
prefixed with 'D1', which probably just specifies it's
usage is for the first demo.
There are 23 references in the executable to LBM image files
Only 17 have been found in the demo build

CS_WINS2.LBM

One of the oddities you'll see above is that
the executable refers to specific paths and
even specific drives! All of these appear to
actually get mapped out to a place
in the executable by some horrible method we
couldn't identify (there don't appear to be
any offsets or lengths?)
_______________________________________________
Can't confirm 100% quite yet, but I believe all
the animations intended for the game are actually
left in the demo
Playing around with the setobjanim script func
allowed me to use some animations I don't recall
seeing in the demo
