100 emulator names the two platforms run had no profile, so their packs carried nothing for them. Each was read from the platform's own launcher or scriptmodule: the same program as an existing profile takes the name in cores:, a different build gets its own profile read from that version, a launcher or self-contained game goes to remove_cores, and the rest are new profiles written from their source or shipped binary. The files they need that the collection lacked are collected from the upstream distributions. Bungie and splitwolf trees are read by path and stay out of dedup.

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.

|
|
|
|
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.
