Technical notes
Same codebase as dosbox_svn_ce, builds against a fake SDL shim (WITH_FAKE_SDL=1) instead of real SDL, for broader platform compat. ref: libretro/Makefile.libretro, libretro/fakesdl/
No MT-32 emulation. src/midi/munt referenced in Makefile.common:15 does not exist, no MUNT submodule. MIDI is hardware-only (ALSA, CoreAudio, CoreMIDI, Win32, OSS) + retro_midi_interface. ref: src/gui/midi.cpp
system_directory set and logged (libretro.cpp:1399-1401), never used to load files. Config uses retro_save_directory (cross.cpp:61-71). Keyboard layouts and codepages embedded in binary. ref: dos_keyboard_layout_data.h, dos_codepages.h
.info firmware_count=0, matches code.
No BIOS or firmware files required.
Why no files
system_directory set but never used for file loading
