notes: |
emux is a multi-system emulator by Sebastien Ronsse. BIOS and cartridge
code identical between upstream and libretro fork (only difference: libretro
adds g_ram_data/g_ram_size exposure in mach/sms.c for RETRO_MEMORY_SYSTEM_RAM).
BIOS loaded via file_map(PATH_SYSTEM, "bios.sms", 0, BIOS_SIZE) in
sms_mapper_init (sms_mapper.c:162-165). Returns false on failure — no HLE
fallback. Mapped at 0x0000, overlays cartridge ROM until bios_disable bit
set in slot control register (sms_mapper.c:79-82).
No hash validation. Code accepts any file >= 8192 bytes.
is_experimental=true. No save states, rewind, or netplay.
