Upstream moved under 145 profiles: 679 refs shifted and 452 followed a renamed file, against 6,483 that still anchor where they were written. The recale rewrites the located ranges only, keeping the annotations and the sentences that carry them, and 106 pins advance in the same commit because refs and source_commit name one revision or the profile describes two at once. Nothing here was guessed. The 183 refs that are CHANGED, GONE or AMBIGUOUS are untouched, and the 57 profiles holding them keep their old pin until someone reads the diff: profile_sync refuses to recale a profile while any of its refs needs a re-read. trident kept its pin too, its annotated ref being one the writer will not rewrite.

|
|
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.
