notes: |
DeSmuME provides full HLE (High-Level Emulation) of all ARM7/ARM9 SWI
routines, making BIOS files optional for most games. When external BIOS
is disabled, a minimal fake BIOS with exception vectors and IRQ handler
stubs is generated at runtime (NDSSystem.cpp:2208-2224, 2263-2278).
External BIOS enables SWI-from-BIOS mode and firmware boot animation.
Firmware boot requires both ARM7+ARM9 BIOS loaded AND interpreter mode
(JIT incompatible, see libretro.cpp:788).
ARM9 BIOS read size: 4096 bytes (0x1000). ARM7 BIOS read size: 16384
bytes (0x4000). No DSi support.
Libretro core option: desmume_use_external_bios (enabled/disabled).
Full HLE of ARM7/ARM9 SWI routines; BIOS files optional for most games.
External BIOS enables SWI-from-BIOS mode. Firmware boot requires both
BIOS files loaded and interpreter mode (JIT incompatible).
No DSi support. Core option: desmume_use_external_bios.
