Technical notes

Same codebase as dosbox_svn, builds against real SDL 1.2 + SDL_net instead of the fake SDL shim (WITH_FAKE_SDL not set). ref: libretro/Makefile.libretro:238

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:61-73). 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
