No BIOS or firmware files required. This core is self-contained.
Game engine re-implementation of Flashback (Delphine Software, 1992) by Gregory Montoir, ported to libretro by Stuart Carnie. Version 0.3.6 (upstream is at 0.5.5).
The core sets need_fullpath = true and valid_extensions = "map" (libretro.cpp:66). Content loading (retro_load_game) extracts the parent directory from the provided .MAP file path and uses it as the data root via FileSystem (libretro.cpp:194-196).
Version detection (libretro.cpp:125-148) probes for these files in order: DEMO_UK.ABA -> DOS Demo INTRO.SEQ -> DOS CD LEVEL1.MAP -> DOS LEVEL1.LEV -> Amiga DEMO.LEV -> Amiga Demo Only kResourceTypeDOS is accepted (line 199); Amiga data is rejected.
Language detection (libretro.cpp:150-174) probes for: ENGCINE.TXT -> English FR_CINE.TXT -> French GERCINE.TXT -> German SPACINE.TXT -> Spanish ITACINE.TXT -> Italian FRCINE.TXT -> French (Amiga) Falls back to English if none found.
All game data files are loaded from the content directory via FileSystem (fs.cpp), which scans the directory and matches filenames case-insensitively (strcasecmp at fs.cpp:52). The resource system (resource.cpp) loads files by constructing names like "LEVEL1.MAP", "GLOBAL.ICN", "PERSO.SPR", "FB_TXT.FNT", etc.
The core never calls RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY. All data files must live alongside the loaded .MAP content file. No BIOS or firmware files; the required files are the original Flashback DOS game data.
Music loaded from .mod files (mod_player.cpp, staticres.cpp:3198-3225). Optional; the core has a built-in SFX player for in-game action music (sfx_player.cpp with embedded music data in staticres.cpp).
VOICE.VCE from the SegaCD version can be placed in the data directory for in-game voice playback (resource.cpp:900-941). Optional.
SEQ cutscene playback is disabled in the libretro build: g_options is zero-initialized (game.cpp:30) and rs.cfg is never parsed, so use_seq_cutscenes defaults to false. The core always uses polygon-based cutscenes (cutscene.cpp).
Upstream (0.5.5) additionally supports Amiga, Macintosh, PC98 data, MIDI music, OGG playback, SEQ cutscenes, and widescreen modes. None of these are in the libretro port.
