Technical notes

Enhanced engine for Tomb Raider 2 (1997), part of the TRX monorepo that also hosts TR1X and TR3X. Loads retail .tr2 level files, the main.sfx soundbank, music tracks and FMV cutscenes from a Steam, GOG or disc install of TR2.

Path resolution (src/trx/game/paths.c): levels %mod_dir%/levels/<file> GAME_DYNAMIC_PATH_LEVEL_FILE sfx %mod_dir%/<file> GAME_DYNAMIC_PATH_SFX_FILE fmv %mod_dir%/fmv/<file><ext> GAME_DYNAMIC_PATH_FMV_FILE music %mod_dir%/music/<name><ext> GAME_DYNAMIC_PATH_MUSIC_DIR with %mod_dir% = games/tr2 under the TRX root. The gameflow.json5, the catalog_*.csv tables, string tables, injections, images and shaders ship inside the TRX zip (data/trx/ship/) and are not user files.

main.sfx is TR2's sample bank. The gameflow sets sfx_path to it (data/trx/ship/games/tr2/gameflow.json5:33) and the level pipeline reads it per level (src/trx/game/level/pipeline.c:179).

FMV extension probing (src/trx/game/paths.c:76-79): .mp4 .mkv .mpeg .avi .webm .ogv .rpl .fmv .bik The retail Core/Eidos cutscenes are .rpl; the gameflow still names them .AVI, resolution picks whichever extension exists.

Music backend (src/trx/game/music/backend_files.c:25-49): extensions .flac .ogg .mp3 .wav .wma file name trackNN.<ext> (two-digit) or N.<ext> Retail TR2 CD rips yield 2.mp3 through 61.mp3 (bare-number form, per docs/trx/INSTALLING.md ship tree).
