Technical notes

No BIOS required. MT-32 and SoundFont support is optional for MIDI music. 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). ref: libretro/src/midi_bassmidi.cpp:232-254 .info declares firmware_count=10 (4 ROMs + 6 BASS libs).
