MAME's search path for a set is the set and every ancestor
(src/emu/driver.cpp:31-38, src/emu/romload.cpp:67-84 at mame0289), so
a clone reads the ROMs it shares with its parent from the parent's
archive. games/arcade/<profile>.json now records, under parents, each
parent game set with ROMs and the clones whose romof chain reaches it
before any BIOS set, and rom_search_sets adds them to what a command
reads. The installer's index leaves them out, as it does the sources.
arcade_parent_importer --all is re-run: every profile gains parents,
and mame0258, mame0278, mame2010, mame2015, mame2016 and fbneo also
gain the sources their committed files lacked.
Manifests, EmuDeck and RetroDECK only: videopac.zip reaches
roms/odyssey2 beside i8244.zip, electron.zip roms/electron, and the 35 parent
sets the profile holds (a7800, apple2e, intv, videopac and others)
reach arcade, consolearcade and mame, the folders whose command starts
any machine. verify --all keeps its severity and status counts.
ES-DE starts standalone MAME with -rompath %GAMEDIR%\;%ROMPATH%/<system>
in 78 live commands across 54 systems (resources/systems/linux/
es_systems.xml at retrodeck-main-20261103-162710, 15e1b236; two more
are commented out). The command line outranks mame.ini, so RetroDECK's
MAME reads its sets in the roms folder each command names and in no
BIOS folder. The ES-DE rom folders parser now records, per folder, the
folders a standalone command passes as its ROM search path and the
machines it starts, or that the game is the machine (%BASENAME%).
Rescraped at the pinned revisions: retrodeck, emudeck and
emudeck-windows gain these records and nothing else.
A command reads the sets its machines load: the machine's own set, the
BIOS sets on its romof chain and the device sets with ROMs it
instantiates, from games/arcade/mame.json (mame0289 -listxml). That
index now also lists the game and device sets of each driver source
file, so a %BASENAME% folder reads for its board: neogeo and stv by
their BIOS root, cps1-3 and model2 by source file, daphne and laserdisc
by the laserdisc player devices, gameandwatch and lcdgames by the
handheld sources, any other (arcade, mame, consolearcade) for every
machine. The published installer copy of the index leaves the sources
out.
Manifests: RetroDECK gains 1399 files, 378.2 MB, below roms/. Of the 219
sets named as read outside the BIOS folder, 58 reach 146 files (25.9 MB),
161 stay named, no command's machine reading them. 441 sets RetroDECK's
list also declares at bios/ reach 1253 files (352.3 MB), 429 each in
arcade and mame and 480 in consolearcade. No other platform changes.
Phase 0 files snk-neogeo-pocket and neo-geo-pocket-color under snk-ngp and snk-ngpc. The No-Intro catalogs, their importer map and the campaign list now use those ids, the games index is regenerated, and the site's name table drops the eleven entries the new aliases leave unread.
duckstation c9dc2254, ares dd737665, Ymir ff935379 and libretro-uae
d366f77c. In system.cpp the boot block only renames
media_playlist_index. libretro-uae adds the A600OG and A500ECS model
tags, the floppy, HD and CD defaults stay A500, A1200 and CD32.
duckstation c9dc2254, ares dd737665, Ymir ff935379 and parallel-ps2
87bcc96b. Each cited block was compared with the code at the new pin.
The region and BIOS logic is unchanged, only line numbers moved.
mame2000, mame2003 and mame2003-plus carry a DAT their code moved past. Their parents and BIOS sets now come from src/driver.c and src/drivers/ at the pin, named by the src tree sha. The DAT is still read to report gaps. FBNeo DATs are read one namespace each, console sets keyed by driver. A BIOS with no dumped ROM is no longer listed.
The games index now names, per arcade core, the game sets that load no
BIOS set and every BIOS set, so a set on a card the DAT does not know is
told apart from one that needs nothing. Each board default core of a rom
folder gets its own fallback set, and index.json maps every folder name
a setup uses to its systems, for a games folder on a computer.
