No BIOS required. MT-32 and SoundFont support is optional for MIDI music.
Libretro mode:
MT-32 ROMs loaded by exact filename from system directory.
mt32.romdir = system_dir (libretro.cpp:652). CM-32L is default type.
ref: src/gui/midi_mt32.cpp:35,51-66
FluidSynth reads .sf2/.sf3/.dls/.gig from system/soundfonts/.
ref: libretro/src/libretro.cpp:1086-1097
BASSMIDI reads .sf2/.sfz from system/soundfonts/, requires BASS +
BASSMIDI shared libs in system dir (dlopen'd at runtime).
ref: libretro/src/midi_bassmidi.cpp:232-254
.info declares firmware_count=10 (4 ROMs + 6 BASS libs).
Standalone mode (DOSBox Staging):
MT-32 ROMs identified by SHA1 hash (MUNT), not filename. Any file in
mt32-roms/ dir scanned and matched. Split ROM pairs supported (_a+_b).
ref: dosbox-staging src/midi/mt32.cpp:109-148 (ROM defs), 470-484 (dir scan)
Default dir: config_dir/mt32-roms/ (dosbox.h:173)
Models: MT-32 v1.04-1.07, BlueRidge, v2.03-2.07, CM-32L v1.00-1.02, CM-32LN v1.00
Sound Canvas (SC-55/SC-155/SC-88) emulation with soundcanvas-roms/ dir.
ref: src/midi/soundcanvas.cpp, dosbox.h:174
SoundFonts in config_dir/soundfonts/ (dosbox.h:175)
ref: src/midi/fluidsynth.cpp:68-69,211
MT-32 ROMs loaded by exact filename from system directory.
mt32.romdir = system_dir (libretro.cpp:652). CM-32L is default type.
ref: src/gui/midi_mt32.cpp:35,51-66
MUNT identifies ROMs by SHA1+size (ROMInfo.cpp:171-180).
FluidSynth reads .sf2/.sf3/.dls/.gig from system/soundfonts/.
ref: libretro/src/libretro.cpp:1086-1097
BASSMIDI reads .sf2/.sfz from system/soundfonts/, requires BASS +
BASSMIDI shared libs in system dir (dlopen'd at runtime).

.info declares firmware_count=10 (4 ROMs + 6 BASS libs).
