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: |
|
|
fixNES is an NES/Famicom emulator by FIX94 (same author as fixGB).
|
|
|
|
FDS games require disksys.rom (8192 bytes) in the system directory.
|
|
mapperInitFDS() in mapper.c:87-110 opens the file, validates exact
|
|
size 0x2000, reads into fdsBIOS[]. Returns false if missing or wrong
|
|
size. No hash validation.
|
|
|
|
Regular NES/NSF games need no BIOS.
|
|
|
|
No other system files loaded. system_dir accessed only for disksys.rom
|
|
(libretro/libretro.c:277-285, doOpenFDSBIOS).
