Schematic explanation of FLA, LDAR, GAM files by vervalkon

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

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)

Information which areas have info files loaded in

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
