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.

# NP2kai is a PC-9801/9821 emulator by AZO234, enhanced fork of Neko Project II
|
|
# by Yui (original upstream dead: np2.yui.ne.jp). All files load from
|
|
# <system>/np2kai/ subdirectory, set in retro_load_game()
|
|
# (sdl/libretro/libretro.c:1800-1815). All getbiospath() calls resolve
|
|
# relative to that directory.
|
|
#
|
|
# BIOS_SIMULATE is unconditionally #define'd (bios/bios.c:78), so the core
|
|
# always has a built-in BIOS simulator. itf.rom loading (bios.c:569) is dead
|
|
# code behind #else of this define and is never executed.
|
|
#
|
|
# .info declares firmware_count=11 but is incomplete: misses IDE, SCSI, SASI,
|
|
# PCI, GPIB ROMs and key.txt. Lists itf.rom which is dead code (phantom).
|
|
#
|
|
# The fmgen YM2608 rhythm engine (fmgen_opna.cpp:1413-1443) loads WAV files
|
|
# with uppercase names (2608_BD.WAV). The built-in rhythm engine (rhythmc.c)
|
|
# uses lowercase (2608_bd.wav). Both resolve from np2kai/.
|
|
# The fmgen engine also accepts "2608_RYM.WAV" as fallback for the rim sample.
|
|
#
|
|
# Sound ROM has board-specific variants tried before the generic fallback:
|
|
# sound26.rom (26K), sound86.rom (86), sound118.rom (118), soundSPB.rom
|
|
# (Speak Board), soundMO.rom (MO), sound14.rom (14). Built as "sound" +
