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.

# Neko Project II (NP2) by Yui, ported to libretro by meepingsnesroms.
|
|
# PC-9801/9821 emulator (80286/IA-32 CPU). All files load from <system>/np2/.
|
|
# The libretro shim sets np2cfg.biospath to "<system>/np2/" and
|
|
# file_setcd() to the same path (libretro/libretro.c:856-864,196).
|
|
#
|
|
# BIOS_SIMULATE is hardcoded (bios/bios.c:26), so the core always has
|
|
# a built-in BIOS simulator and ITF ROM is never loaded from disk.
|
|
# Font data falls back to built-in 8x8 tables. Sound ROM falls back
|
|
# to a 9-byte stub. IDE/SCSI/SASI all have built-in stubs.
|
|
#
|
|
# This is NOT the same core as np2kai. Different repo, different
|
|
# feature set (no fmgen, no IDE/PCI/GPIB ROM loading, no itf.rom).
|
|
# BIOS path is np2/, not np2kai/.
|
|
#

|
|
# loads multiple BIOS/font/sound files but all have built-in fallbacks.
