Technical notes

Frozen 2015 snapshot of DeSmuME. The core emulator code supports external BIOS/firmware (PrepareBiosARM7/ARM9 in desmume/src/NDSSystem.cpp:1957-2033), but UseExtBIOS defaults to false (desmume/src/NDSSystem.h:497) and the libretro frontend never sets it — no desmume_use_external_bios core option exists in this version. Uses HLE BIOS stubs when external BIOS not loaded.

No BIOS or firmware files required.

Why no files

.info declares firmware_count=3 but libretro frontend never enables external BIOS loading (UseExtBIOS defaults false in desmume/src/NDSSystem.h:497, never set in libretro.cpp)
