Technical notes

No BIOS required. MT-32 and SoundFont support is optional for MIDI music.

ROM scanning (both modes): Recursive scan of system directory for _CONTROL.ROM and .SF2/.SF3. ref: dosbox_pure_libretro.cpp:1399-1410 MT-32 requires matched pair: _CONTROL.ROM + *_PCM.ROM (PCM name derived from CONTROL name by replacing CONTROL with PCM, preserving case). ref: midi_mt32.h:189-199 ZIP archives also supported — scanned for files by size (65536/131072 = control, 524288/1048576 = PCM), not by name. ref: midi_mt32.h:160-166 Files can also be on mounted C: drive (DOSBOX.SF2, MT32_CONTROL.ROM). ref: dosbox_pure_libretro.cpp:2803-2805 Cache file DOSBoxPureMidiCache.txt written when scan >2s. ref: dosbox_pure_libretro.cpp:1425-1445

Bundled MUNT (header-only mt32emu.h) for MT-32 emulation. SHA1+size validation at load: unrecognized ROMs rejected (Synth::open fails). ref: mt32emu.h:2982-2988,3016-3019,5183-5187 12 full control ROMs + 2 PCM ROMs supported (no split ROMs in this MUNT). TinySoundFont (tsf.h) for SF2/SF3 playback. No firmware entries in .info file — all MIDI files optional.

DBP_STANDALONE build mode exists (same MIDI logic, different I/O layer). ref: dosbox_pure_libretro.cpp:81,1590,2302
