Technical notes

Based on DOSBox 0.74 snapshot. MUNT MT-32 emulation added by libretro port. Upstream DOSBox 0.74 has no MUNT — only OS-level MIDI (ALSA, CoreMIDI, Win32). Hardware MIDI drivers removed, replaced with retro_midi_interface passthrough. MT-32 activated via mididevice=mt32 in dosbox config section [midi]. Older MUNT version: no MT-32 v2.x ROMs, no CM-32LN support. Both ROMs loaded by fixed filename from system directory root. ref: midi_mt32.h:82-106 Keyboard layouts and codepages embedded in binary. ref: dos_keyboard_layout_data.h, dos_codepages.h .info declares firmware_count=0 but code loads 2 files (MUNT ROMs). dosbox-libretro.conf optional config searched in system_directory/DOSbox/. ref: libretro.cpp:751
