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.

notes: |
|
|
emux is a multi-system emulator by Sebastien Ronsse. The libretro port
|
|
renamed the boot ROM from DMG_ROM.bin (upstream, controllers/mapper/gb_mapper.c:32) to
|
|
dmg_boot.bin (libretro, controllers/mapper/gb_mapper.c:35) to match RetroArch conventions.
|
|
|
|
Boot ROM loaded via file_map(PATH_SYSTEM, "dmg_boot.bin", 0, 256) in
|
|
gb_mapper_init (controllers/mapper/gb_mapper.c:225-228). Returns false on failure, no HLE
|
|
fallback. Mapped at 0x0000-0x00FF, overlays ROM0 until BOOT_LOCK (0xFF50)
|
|
is written non-zero (lock_writeb, controllers/mapper/gb_mapper.c:97-106).
|
|
|
|
No hash validation. Code accepts any 256+ byte file.
|
|
is_experimental=true. No save states, rewind, or netplay.
