DS and DSi split into Nintendo DS and Nintendo DSi. 64DD, Mega-CD,
ZXSpectrum, VSmile, BBC and Game Engines/DOOM merge into the folder
of the same console. Same-named dumps with other bytes are kept:
BBC Micro's earlier zips in .variants/, the vsmilem set in vsmilem/,
the Doom II 1.666 IWAD in v1.666/, BizHawk's DSi firmware in bizhawk/.
Galaksija and Vircon get a console folder, sdlpal's desc.dat joins
its tree, VICE's PET and CBM-II ROMs leave C128 with their vice/ tail.
Database and manifests regenerated together. Verify and cross
reference give the same result once moved paths are mapped.
AmberELEC, PAN4ELEC and EmuELEC detection now installs their own lists
at /storage/roms, the root those lists are written against; KNULLI its
own list at /userdata/bios. JELOS, KOLOS, UnofficialOS and Arch R keep
RetroArch's list with the folder their retroarch.cfg names.
Pin moves to 2de3bf8 (v8.4.2). roms/aros-ext.bin, roms/aros-rom.bin and whdboot/game-data/whdload_db.json changed upstream and are collected at that revision. The WHDLoad database is matched on the archive SHA1 first and refreshed from the bundled copy when newer. kick02019.AROS and its .ext are names the Recalbox launcher writes, so the profile now documents the kickstart_rom_file settings instead.
55 device sets the collection lacked or held incomplete. 24 are rebuilt from ROMs already in bios/, 31 come from the archive.org item mame-roms-non-merged. Every member matches the 0.289 listxml size, crc32 and sha1, and each archive is built with build_torrentzip. The complete nss_tvinterface goes to .variants since RetroDECK pins the incomplete copy. The old at_keybc.zip held two of the three ROMs, its md5 is pinned by no platform, and is replaced by the complete set RetroDECK pins (63536a7d). Database and install manifests are regenerated with the files, including the vMac.ROM move.
RomM lists a platform's firmware folder without descending (base_handler.py:1002, recursive=False) and EmulatorJS writes the chosen file, or each zip member, under its bare name. 543 files of the RomM pack sat below a folder where no core could read them. The registry now marks RomM's folder flat, and such files are omitted with the reason below_platform_folder in the manifest and the installer.
opera-boot.bin, blueMSX's own RS232.ROM, the GameCube IPLs filed under their system, and Triforce's codehandler.bin from the Dolphin Sys tree the pack carries.
Manifests list each data directory's source archive and the hash of
every file; the installer rebuilds the tree from the archive and keeps
only the files whose hash matches.
The RetroArch list is folded for Windows and macOS. Its manifest
now carries the names a case-keeping directory also needs, and the
installer adds them after probing the BIOS directory.
The new-format hiscore.dat was served by name to cores whose parser reads
only legacy lines. Eight cores now pin the hiscore.dat their own
repository ships, four revisions newly collected.
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.
