XRoar reads a ROM by name from the directories of rompath. The entries
take their file name as path, relative to ~/.xroar/roms or
${prefix}/share/xroar/roms, and rompath and -rompath are declared as
search lists.
Batocera records its rompath line, Recalbox -rompath bios/<system>
(the placeholder its extractor already writes), RetroBat its -rompath
as two records, bios/dragon and bios/coco for coco. An entry whose
name the platform list does not declare follows the launch its
profile system is listed under: Recalbox lists mc10.rom under
trs80coco, so alice.rom is read there.
Batocera ROMs move from the BIOS root to bios/xroar, Recalbox ROMs to
bios/dragon and bios/trs80coco, RetroBat ROMs to bios/dragon and
bios/coco. RetroDECK and RetroPie keep them at the BIOS root.
Batocera, RetroBat, Recalbox and ROCKNIX offer some emulators both as a
libretro core and standalone. Filed as standalone only, the libretro
layout was dropped: libretro Dolphin had no dolphin-emu/Sys/GC files.
Platforms now name dual-mode emulators and each gets both layouts.
Thirty platform system ids, such as sufami, pokemini, vsmile, and
Recalbox's comma-joined msx1,msx2, matched no system any profile
names, so no core file was attributed to them and --system missed them.
The scraper maps now carry those names, and a test holds every platform
system to a profile system apart from two named folds.
RetroDECK filed coco as tandy-coco and Dragon as dragon-32-64, MiSTer
filed COCO3 as tandy-coco and Recalbox kept its raw ids, so none of
them met xroar's coco, coco3 and dragon64 and its ROMs reached no
system. The scraper maps now agree and a test holds every shared
native id to one system.
es_bios.xml names only the cores that need a BIOS, so a hand-kept
registry list stood in, with mame and mamemess that Recalbox does not
ship and without vice, ymir, vircon32 and others it does. The scraper
now reads each system.ini of recalbox-romfs2 at the scraped tag, and
the registry list is gone.
resolve_platform_cores() links platforms to their cores via
three strategies: all_libretro, explicit list, system ID
fallback. Pack generation always includes core requirements
beyond platform baseline. Case-insensitive dedup prevents
conflicts on Windows/macOS. Data dir strip_components fixes
doubled paths for Dolphin and PPSSPP caches.
