Filetypes

Filename	Description
0*.EVN	Events files containing dialogues and some game logic. Event files are read from disk during the "LOADING" screens, so when using a savestate you may be loading an older version. Use the ingame Debug Mode to easily test these. The current event file is loaded in RAM @ 0x29E000
*.CHR	Sprite texture data. Goes with *.PAK of the same base name. Also used to store the doorway signs.
*.PAK	Sprite Pack. See PAK Format. Hacked only to resize the doorway signs.
*.PCM	A symlink to a cd audio track. The LBA in the cd's file table for the file must match the actual location on the disc or it won't play.
*.PRG	Program binary(SH2). Most of them handle some NPC behavior or enemy AI.
*.CHB	8x8 4/8 BPP Tile data. Used for VDP2 backgrounds.
*.MCB	Tile Map data for above files. See MCB Format
*.SND	TON banks. Basically audio for Sound effects, music, etc.
*.MPB	More tile map data. 2 bytes map data per tile?
*.CLB	Color Palette. Each entry is 2 bytes, rgb 555, highest bit is unused.

Files reference

Filename	Description
0.BIN	Main Program. Pretty much anything related to the main part of the game including game events, text rendering, etc. is handled here. It is loaded from the disk only once when the game is booted, so when using savestates you may be loading an older version.
KANJI.BIN	Main font for dialogue, items, etc. 12x12 tiles. In the English-patched version the Latin alphabet is stored starting from offset 0x4380 (related issue). Confusingly, the same file is also used to store the items names and descriptions due to insufficient space in 0.bin (related issue)
OPENING0.EVN	Opening cutscene before starting the game.
SELECT.EVN	Book Selection area when you start a game.
COCKPIT.CHB	Save Menu Tile data. See related issue
