Profiles that read two repositories, a libretro port and its upstream, now prefix each citation with source or upstream, decided by which tree carries the cited value at its pin. The emulator pages use the word to tell libretro glue, emulator code as the port carries it, and the upstream emulator apart.

|
|
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 (controllers/mapper/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 (controllers/mapper/sms_mapper.c:79-82).
|
|
|
|
No hash validation. Code accepts any file >= 8192 bytes.
|
|
is_experimental=true. No save states, rewind, or netplay.

note: "Mapped at 0x0000, overlays cartridge ROM until bios_disable bit set. file_map rejects files < 8192 bytes (main/file.c:59)."
