LDAR
- Contains information on how to build the VRAM page for that area
- Best guess: LDAR tells which files to load to RAM. In these files, there's the Xfile
- are explicit instructions that tell the game which D-files build a level
- are very small and contain some data that when aligned to a certain width, look "right"
- possibly LDAR means LoaD ARea
XFile
- Xfile controls (probably) asset/npc placement and geometry loading (probably), but likewise it needs to call the WSS
- the first 0x2DE6C bytes are always the same, no matter which X file you're looking at
WSS
- controls the script and event flow but it needs to call the WFMs so it can get content
WFM
INFO
- not all levels have an INFO file
- INFO files contain instructions on how to build (and possibly send over to VRAM) the 2D maps sections
- SYSTEM folder has also copies of INFO, INFO2 and INFO3 (54, 137 and 39 kb, respectively)
D-File
- The first four bytes of any given D-file is $AMOUNT Immediately after it, there are exactly $AMOUNT number of 4-byte pointers
- Some D-files are different from others, as they don't contain any face data, only coordinates in the 3D space
