# WH40K: Chaos Gate
Re-implementation of the WH40K binary using SDL.
Re-implementation of the WH40K binary.
**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

StdWeap.dat # SQUAD STANDARD WEAPONS
Ultnames.dat # List of names for ultramarines

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
This README is a grab-bag of miscellaneous information about file formats at
present. This is being migrated to the [Formats overview](doc/formats/index.md)
as a precursor to making this file useful!
No game yet, nothing even close. I'm in the very early stages of trying to
understand the various file formats. Until then, you can play WH40L: Chaos Gate
in a WinXP VM, disconnected from the internet. It doesn't need 3D rendering!
"Mission Setup" includes information about available squad types
From EquipDef.cpp Dumo: CEquipment we learn the following object types:

Last 8 bits would then actually be the start of the image, but there's a lot
of similarity between them...
It smells a bit like a DIB:
| Offset | Size | Example | Purpose |
| 0 | 2 | D1 00 (209) | ?
| 2 | 2 | 41 01 (321) | ?
| 4 | 2 | 80 00 (128) | Width? |

Now, how to convert the pixel data to an image?!?!
Average bits per pixel seems to be less-than-1, e.g. for crates.obj:

So some form of compression? RLE?
How does WH40K_TD.EXE draw these?
