No BIOS or firmware files required. This core is self-contained.

Open-source reimplementation of the classic Tomb Raider engine (TR1-TR4). Supports PC (.PHD, .TR2, .TR4), PlayStation (.PSX), and Saturn (.SAT) level formats. The core accepts phd|psx|tr2|sat extensions (retro_get_system_info sets valid_extensions, main.cpp:246). need_fullpath is true - the core resolves sibling game assets relative to the content directory. retro_load_game (main.cpp:602) derives contentDir from the loaded level file path and strips the level/ subdirectory if present, then passes a relative levelpath to the engine. Game version is auto-detected by probing for known level files: DATA/GYM.PHD (TR1 PC), PSXDATA/GYM.PSX (TR1 PSX), DATA/GYM.SAT (TR1 Saturn), data/ASSAULT.TR2 (TR2 PC), DATA/ASSAULT.PSX (TR2 PSX), data/JUNGLE.TR2 (TR3 PC), DATA/JUNGLE.PSX (TR3 PSX), data/angkor1.tr4 (TR4 PC) - see gameflow.h:1047-1071. Audio tracks are loaded from audio/ subdirectories as .ogg files or cdaudio.wad containers (gameflow.h:1248-1350). The system directory is used only to create a cache folder at {system_dir}/openlara/cache/ (main.cpp:177-197). No BIOS, firmware, or engine data files are required in the system directory. All required data comes from the original game files loaded as content.
