Technical notes

Open-source reimplementation of the classic Tomb Raider engine (TR1-TR4). Accepts phd|psx|tr2|sat extensions (src/platform/libretro/main.cpp:246). need_fullpath is true - the core resolves game assets relative to the content directory. retro_load_game (src/platform/libretro/main.cpp:602) derives contentDir from the level file path and strips level/ if present. Game version auto-detected by probing for known level files (src/gameflow.h:1047-1071). Audio tracks loaded from audio/ subdirectories as .ogg/.mp3/.wav files or cdaudio.wad (src/gameflow.h:1272-1356). System directory used only for shader cache at {system_dir}/openlara/cache/ (src/platform/libretro/main.cpp:177-197). No BIOS, firmware, or engine data files required in system directory. The code declares the sat extension, which the .info supported_extensions does not list.

No BIOS or firmware files required.

Why no files

The system directory holds openlara/cache, which the core creates (src/platform/libretro/main.cpp:177-196) and fills with the shader program binaries and cache streams it writes itself, read back only as a cache (src/gapi/gl.h:810-816, src/utils.h:2361-2367). Nothing in it is supplied by the user.
