A prose citation whose text lived under several pins stayed in read again until the text changed, so fixnes, zesarux and emucorex, exact at their pins, would have refused every later bump. prose_written_at names the pin a reader confirmed; it settles the readings and never overrides a history with one candidate.

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).
