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.

notes: |
|
|
Geolith emulates the Neo Geo AES, MVS, CD, and CDZ. Cartridge systems use
|
|
.NEO format ROMs; CD systems use .cue or .chd disc images. System ROMs come
|
|
from MAME-format ZIP archives in the system directory.
|
|
|
|
Cartridge content opens aes.zip (System Type = AES, default) or neogeo.zip
|
|
(MVS and Universe BIOS) (libretro/libretro.c:1243-1246). CD content opens
|
|
neocd.zip (Front/Top Loader) or neocdz.zip (CDZ, default, and CD Universe
|
|
BIOS) (libretro/libretro.c:1234-1242); Front/Top Loader additionally reads
|
|
000-lo.lo from neocdz.zip, so neocdz.zip is needed in every CD mode
|
|
(libretro/libretro.c:1253-1260). The Irritating Maze in MVS mode loads
|
|
236-bios.sp1 from irrmaze.zip for trackball support; without it the game
|
|
runs but the trackball does not work (libretro/libretro.c:1312-1323).
|
|
|
|
Inside the opened archive, members are extracted by exact filename
|
|
(src/geo.c:174-271). One 68K BIOS is selected by system type and region
|
|
(defaults: System Type AES, Region USA):
|
|
- AES Japan: neo-po.bin
|
|
- AES other regions: neo-epo.bin
|
|
- MVS USA: sp-u2.sp1
|
|
- MVS Japan: japan-j3.bin
|
|
- MVS Asia: sp-45.sp1
|
|
- MVS Europe: sp-s2.sp1
|
|
- Universe BIOS: uni-bios_4_0.rom
|
|
- CD Front Loader: front-sp1.bin
|
|
- CD Top Loader: top-sp1.bin
|
|
- CDZ: neocd.bin
|
|
- CD Universe BIOS: uni-bioscd33.rom
|
|
000-lo.lo is required in every mode; only the Front/Top Loader tolerates
|
|
its absence from neocd.zip because it comes from neocdz.zip instead
|
|
(src/geo.c:234-243, 273-285). sfix.sfix and sm1.sm1 are required for MVS
|
|
and Universe BIOS modes only (src/geo.c:245-267).
|
|
|
|
The core performs no hash or size validation on System ROMs. CD BIOS family
|
|
detection and the optional CD speed hack patches use byte patterns and
|
|
apply only when the 68K BIOS is at least 512 KiB (src/geo_cd.c:1888-1910,
|
|
1904-1924). Upstream declares the expected archive MD5s through the Jolly
|
|
Good API BIOS list (jg.c:220-231); the md5 fields on the archives below
|
|
are copied from it.
