Each standalone profile records where its version is read: the source at its pin (clk 2026-07-23-136-g9020107, shadps4 0.20.1 WIP, eden v0.2.0-401-g26a03d2), the APK, binary or archive read (kind package), or, where no reading can be made, kind unverified with the reason: a host the tools cannot read, a forge gone or not answering, no build recorded as read, a pin on another branch. Those keep their value, unconfirmed.

Raspberry Pi build of Gngeo by Yannick Martel, imported as the Gngeo 0.8
|
|
tree of Mathieu Peponas (gngeo/configure.in:3) and released as 0.85. The
|
|
repository is not a git fork of any Gngeo history. RetroPie builds
|
|
gngeo/, installs it to its own prefix and launches it with
|
|
"-i $romdir/neogeo -B <prefix>/neogeobios".
|
|
|
|
-B sets biospath, an option the code defines and never reads. The BIOS
|
|
archive is opened from rompath, the -i directory, as neogeo.zip. The same
|
|
archive is opened as the parent of every game whose definition names
|
|
neogeo as parent, and a missing parent ends the load.
|
|
ref: gngeo/src/conf.c:416-425, gngeo/src/roms.c:1217-1235,1364-1375
|
|
|
|
Members of neogeo.zip are found by exact name only, dr_load_bios passing no
|
|
CRC. 000-lo.lo is read for every game. The board fix layer is read as
|
|
sfix.sfx then sfix.sfix, unless the game's definition loads it itself. The
|
|
68K BIOS follows the system option (arcade by default) and the country
|
|
option (europe by default): unibios reads uni-bios.rom from the archive or
|
|
loose from rompath, home reads aes-bios.bin, and arcade reads vs-bios.rom,
|
|
usa_2slt.bin, asia-s3.rom or sp-s2.sp1 for japan, usa, asia and any other
|
|
country. A member that is not found ends the load.
|
|

|
|
gngeo/src/conf.c:119-142, gngeo/src/emu.h:34-43
|
|
|
|
Game definitions come from gngeo_data.zip, the datafile installed to the
|
|
package data directory, as rom/<game>.drv: 237 definitions, each giving the
|
|
parent and every member with its region, size and CRC32. A game member is
|
|
looked up by name or CRC32 in the game archive, then in the parent. A miss
|
|
in the audio BIOS, fix BIOS or 68K BIOS regions is tolerated, any other miss
|
|
ends the load. 58 definitions name a BIOS member: sfix.sfix (CRC32
|
|
c2ea0cfd) in the fix BIOS region, sm1.sm1 (CRC32 94416d67) in the audio
|
|
BIOS region for neogeo, irrmaze and the svc bootlegs, and board BIOS images
|
|
that live in the game's own archive (236-bios.bin for irrmaze, 271-bios.bin
|
|
for kf2k3pcb, sp-4x.sp1 for ms5pcb and svcpcb).

|
|
gngeo/src/roms.h:8-17,25-40
|
|
|
|
The CMC42 and CMC50 key tables are read from the same datafile, the older
|
|
direct reads from the author's home directory being commented out. The
|
|
datafile also holds the menu skin.
