I can parse some of the data files, and extract individual frames from .obj
files. I can't yet convert those frames into something viewable.

# WH40K: Chaos Gate
Re-implementation of the WH40K binary using SDL.
**You must have a copy of the original game data to use this project**
Files:
```
Anim/
WarHammer.ani # Doesn't seem to be a RIFF file. 398M so very important.
* There's a pcx image header at `dd ... bs=1 skip=213` but it seems to be a false alert
* Hits for "AmigaOS bitmap font"... probably a false positive
* Lots of 8-byte reads when loading stuff in the mission editor
* Some ~4K reads, havent found one corresponding to a known format yet
Assign/
*.asn # Unknown, seems to be related to .obj files
Cursor/
*.ani # RIFF data
*.cur # Presumably standard windows-format non-animated cursors
Data/
*.dat # plaintext files defining properties of objects. No single format
PARSED:
Accounting.dat # key = value => internal/data/accounting.go
AniObjDef.dat # animated object definitions
GenericData.dat # Generic Game Settings
IN PROGRESS:
TODO:
ChaNames.dat # list of character names
Coordinates.dat # Weapon Firing Coordinates
Defs.dat # defines properties for objects and tiles, each of which seems to have an id
GDestroy.dat # table of what destroys what?
HasAction.dat # "Are there animation for each of the character" - list of booleans
MiniMap.dat # lots of seemingly random numbers. IDs?
MissionBriefing.dat # Contains all Campaign Mission Briefing Text. Sections: "CAMPAIGN MISSION X ... END CAMPAIGN MISSION X"
PWeight.dat # Personality weights for the individual character types
Random_AI.dat # contains the percentage of the different AI types for each of the different Chaos Squad Types
RandomPlanets.dat # Campaign Primary and Secondary Objectives
Sounds.dat # Sound Effect Data
SpellDef.dat # SPELL DEFINITIONS
StdWeap.dat # SQUAD STANDARD WEAPONS
Ultnames.dat # List of names for ultramarines
VehicDef.dat # VEHICLE DEFINITIONS
WeapDef.dat # Weapon definitions
PROBABLY NOT NEEDED:
BugHunt.dat # Contains SMF text for Bug hunt random missions
Credits.dat # list of credits
GenArm.dat # "Random campaign armory levels - space marine"
HeroArm.dat # "Random campaign armory levels - Veteran"
MHeroArm.dat # "Random campaign armory levels - Veteran"
PlanetDesc.dat # well-documented params. random mission generator params per planet.
RandChar.dat # Random character matrix. Information on what goes into a character matrix.
RandSMFtext.dat # SuperMacro Objectives for Campaign Random Mission Generator.
SpArm.dat # "RANDOM CAMPAIGN ARMORY LEVELS - Veteran"
VetArm.dat # "RANDOM CAMPAIGN ARMORY LEVELS - Veteran"
*.chk # checksums? Mentions all the .dat files
*.cyc # ColorCycle DataFile.
*.dta # localized strings and things
Encyclopedia.dta # encyclopedia entries
KeyMap.dta # unknown
Keymap.dta # unknown
USEng.dta # Localized strings
EquipmentMenuData # gzip-compressed, presumably to do with (initial?) squad configuration
Filters/
wh40k.flt # Audio filter(s?)
Fonts/
cboxfont # unknown
*.fnt # ASCII text. Map keycodes to sprites?
*.spr # sprites, presumably
Idx/
WarHammer.idx # unknown, 1.8M
Maps/
*.MAP # gzip-compressed, must be map definition, contains `WHMAP` constant and character names
*.TXT # scenario text
Menu/
*.mnu # plain text, linked to .obj file, contains definitions
*.obj # unknown, not 3D .obj format
Misc/
occlusio.lis # plain text, presumably occlusion mappings?
MultiMaps/
*.MAP # Like Maps/
*.TXT
Obj/
*.obj # must be visual data of some sort, one per placeable map object?
Pic/
*.pcx # Standard .pcx format
RandomMaps/
*.chk # multiplayer. worry about these another day
*.dat
Save_G/
*.sav # savedata, gzip-compressed, custom format
*.txt # Seems to be a copy of one of Maps/*.txt
Sets/
Data.chk # checksums? Mentions all the .set files
*.set # plain text, related to maps, lists a set of .obj files for that map?
SMK/
*.smk # Videos: RAD Game Tools Smacker Multimedia version 2
Sounds/
wh40k.ds # 0xffffffff then a list of .wav file names. Some sort of index?
Wav/
*.wav # normal WAV files, all mentioned in Sounds/wh40k.ds
```
WH40K.exe is the existing game engine
WH40K_TD.exe is the map editor. Allows things to be saved as .MAP or as .SMF
("Super Macro File")
"Mission Setup" includes information about available squad types
From EquipDef.cpp Dumo: CEquipment we learn the following object types:
0. DELETED
1. WEAPON
2. GRENADE
3. MEDIPACK
4. SCANNER
5. GENESEED
6. CLIP
7. DOOR KEY
8. DOOR KEY
9. DOOR KEY
10. DOOR KEY
And we learn they can be "on"....
0. CHARACTER
1. VEHICLE
2. CANISTER
Hypothesis: Idx/WarHammer.idx points objects into bitmap data in Anim/WarHammer.ani
We can use WH40K_TD.exe and investigate reads of .idx followed by reads of .ani
to test this.
Obj/*.obj and Assign/*.asn files seem to have some identity
WH40K_TD.exe opens files in this order:

jungtil.asn references 18 frames (0-17) and a `jungtil.flc`, which is an AutoDesk format
We read jungtil.obj in about that number of blocks. Presumably each is a frame
in some format or another, but seemingly *not* FLC.
Here's our list of reads:
| Offset | Size | Gap | Purpose |
|--------|------|-----|---------|
| 0 | 32 | 0 | Main header
| 32 | 144 | 0 | Frame headers
| 176 | 463 | 0 | Frame 1

20 reads in total.
The following chunks are identical:
```
* 176 and 49736 (all 463-byte frames)
* 63078 and 67407 (all 4329-byte frames)
```
Here's the hex of the first 32 bytes:
```
0 1 2 3 4 5 6 7 8 9 a b c d e f
0x0000 12 00 00 00 20 00 00 00 90 00 00 00 B0 00 00 00
0x0010 88 17 01 00 00 00 00 00 00 00 00 00 00 00 00 00
```
* Offset 0 = 0x12 = 18 = the total number of frames ?
* Offset 4 = 0x20 = 32 = the size of the this block ?
* Offset 8 = 0x90 = 144 = the size of the next block ?
* Offset c = 0xB0 = 176 = the offset of the third read, or the size of the first two blocks combined ?
Need to unpack a few more objs to check what these numbers do. They could all
be 32-bit LE integers too.
0x10-0x13 as a 32-bit LE is 71560.
Total file size (71736) - 32 - 144 = 71560 = size of all frames combined
Obj/j_tree02.obj doesn't seem to adhere to these rules at all...
Then the next 144 bytes:

```
8 bytes per frame (8*18=144).
First four bytes in each line are the position relative to the start of the
first frame (i.e., minus the size of the first two blocks).
Last four bytes in each line are the total size of the frame, header + data.
Then there are 18 blocks of varying size. These must be the frames. First 32
bytes of all 18 blocks has a lot of similarities:

Remainder of each block is highly variable, so probably pixel data, and
(some of?) these 32 bytes are header data
bytes 4-7 could be dimension?
Tiles are 64x64 pixels (I think?), displayed in an isometric fashion, so I am
wrong or it's something else.
bytes 12 & 13 as LE 16-bit (or 12-15 as LE 32-bit) is always 24 bytes under full
block size.
Perhaps we have 24 bytes of header and that's the header-exclusive pixel data size?
Last 8 bits would then actually be the start of the image, but there's a lot
of similarity between them...
Now, how to convert the pixel data to an image?!?!
