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 libretro/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/libretro.cpp:1438-1440), never used to load files. Config uses retro_save_directory (src/misc/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.
