File formats in map data
BUF
- no header
- ASCII resource names throughout
- identifiers at the end
- random data referenced externally?
- not present in ErrorMessages
- contains GMS instance names
- contains GMS instance auxiliary buffers (not understood)
GMS - entities
- compressed
- cross-refs to PRM - mostly understood, able to render entire scene into .obj
- refers to function names (script not figured out yet)
LOC - hierarchical localization data
- fully understood
- not present in ErrorMessages
OCT - ?
PRM - object geometry
- we're able to enumerate models
- dump OBJs with correct vertex positions and load those into Blender
- doesn't describe model placement in world (see GMS)
- a lot of questions remain
- doesn't seem to contain world terrain (??)
RMC - ?
RMI - ?
SGP - ?
SND - ?
SUP - ?
TEX - textures
- texdump managed to parse everything we tried
- also contains reference to WAV files - this part is not understood
ZGF - compressed font collection
- able to reliably decompress
- unable to reliably tell font boundaries
- (probably not very interesting)
