A platform can hand each libretro core a system directory of its own
(core_system_dirs). platform_layouts then gives one view per directory,
so the gap report, the builder, the manifest, slots and cross_reference
place a core's files below each folder it is handed, and a core handed
none gets no file. Resolution strips the folder again and searches the
collection by the core's own path.
The -listxml names, for every machine, its parent (romof), the devices of its default configuration (device_ref) and the cards its slots offer (slotoption). A machine takes the system of the first set on its romof chain a written entry lists, and passes it to each device it can instantiate. A device set reached from one system gets system:, from several the new per-entry systems:, from none neither, and keeps serving every system of the profile. The gap report, the core extras and slots read the entry's own systems, so generate_pack --system and the installer pick by them.
After --all-variants, --verify-packs printed "hashes checked during the
build" for the platform-only, truth and required-only packs and compared
none of them, so one missing a file its narrowed list requires passed.
Each pack is now held to the platform list narrowed the way it was built:
source and required_only, read from its name, reach the baseline, the
region grouping and the replay of the core extras.
generate_pack and verify read --system beside --platform through common.resolve_system_arg, built on platform_system_names, the mapping the manifest's system_names comes from. verify --platform --system now reports on the narrowed pack. Unknown names are refused with suggestions before the database is read.
A core extra resolved by name shipped on existence platforms even when
the core's own size check turns the copy away. The RetroPie pack carried
the 128 KB Apple IIGS ROM as Basilisk II's ROM (min 512 KB). The builder,
the manifest and verify now read validation.core_size_refusal, which
accepts a copy any version of the same profile slot takes.
The pack integrity check rebuilt the core extras with no taken paths and
tested presence alone, so it credited core files at paths the platform's
own file holds and printed a core count the builder contradicted. It now
replays the builder's placement through packextras.hidden_extras and
compares each placed member with the copy the builder resolves.
The second pass, the archive-prefix pass and the agnostic scan built
extras without source_name or source_path, so verify found no gap report
entry for them and counted game data such as hiscore.dat as core files.
Every extra now carries its entry's category and key, and verify reads
the category from the extra the builder places.
verify resolved platform entries with common.resolve_local_file and put
the slot override first, and the region pass added a destination hint.
packresolve.resolve_declaration now serves the builder, the manifest,
verify and the region pass: release assets cached for a file absent from
bios/ count as shipped in all four, and a release asset keeps its answer
over a slot override.
Ranking contested core claims sorted the whole gap report, which
reordered every manifest. Only the claims on one contested path move now,
grouped where the first of them stood, and two spellings of a path are
one group where the filesystem folds case (RetroBat's 64DD_IPL_DEV.bin).
An entry without a destination (EmuDeck's system:md5 whitelist) no
longer counts as a pack path in verify, and step 5 prints one status for
counts and paths together. A full offline run compared all 12 archives
and 930 emulator packs path by path, every one equal.
A destination no platform declares went to the first claimant in profile
order whatever the proof: fbalpha2012 asks for hiscore.dat by name and
took the root of six packs over cores that pin it by sha1. Claims on a
contested path are now ranked by what the collection holds for each (a
held declared hash, then a path or every required archive member, then a
name, then a contradicted hash), and profile order only breaks ties.
Measured: 14 slots change file across the platforms, among them
hiscore.dat, kick13.rom on RetroPie, cgb_boot.bin and dmg_boot.bin on
EmuDeck, and ROCKNIX neogeo.zip and neocdz.zip.
emulator_region_drops counted as held any file that resolved. A regional
dump whose md5 the core's own check refuses won its region, the fallback
was withdrawn, and the emulator pack then refused the winner: no BIOS for
the system, and verify --emulator, reading the same drops, did not see
it. Held now means what the builder ships, as _ships decides on the
platform side.
The region grouping and phase 2 of each pack and manifest called
find_undeclared_files with the same arguments: 30 reports for the 15
manifests of --all --manifest, 2.8 s, now 15 and 1.7 s. The 15 manifests
are byte-identical before and after.
Step 5 compared (ok, total) and the core file count. RetroArch, Lakka
and RetroPie read 526/526 on both sides while verify credited four paths
below SGB1.sfc and SGB2.sfc that the pack never writes: a declared file
blocks them as a directory. verify now places the platform files in the
builder's order with the same path rules, and a user_provided or
external declaration keeps its slot on both sides, so no core file takes
it in the report only.
verify --destinations writes the paths each pack holds by the report,
and step 5 compares them with the archive members (notes and data tree
members set aside). Every emulator profile, in each build it has, is
built in memory (PackRecord, nothing read or written) and compared with
verify --emulator path by path. Cost measured here: about 1 s per
platform archive and 11 s for the 930 emulator packs.
A file a core reads at several destinations is added again at each one by a second pass that worked from the raw profile entries, so files the emulator or the platform's package installs came back into the packs and manifests by that route: the installer's per-target replay disagreed with the builder on six files.
A file or tree installed with the emulator is already on the user's machine, so packs, install manifests and verify's pack count leave it out. bundled is scoped by mode like any entry: Dolphin's Sys and PPSSPP's assets ship with the standalone releases, not with the libretro cores, so they now follow the libretro build only and still reach RetroArch packs. PrimeHack, standalone only, ships its own Sys.
The report counted claims, not files: several cores claim one path (rom.key by three Amiga cores, openbios.bin with and without a region) and the builder ships one file there. RetroArch read 1130 core files, 48 more than its pack. Game data ignored the in_pack marker, so RomM read 351 game data files in a pack that holds none. verify now takes both counts from its replay of the builder's placement, one per pack path.
verify replayed the builder's placement of core files with a bare name lookup, without the archive index, the data directories or the core's own choice of copy. It compared other bytes than the pack's (blueMSX's MSX2P.rom from bios/ against the data tree's copy) and let an unresolved file take a path the builder leaves free. ExtraResolver now holds the builder's lookup and both call it.
verify kept its own copy of the placement rule and missed the flat RomM folder, so the report still counted 543 unreachable files as packed. It now asks the builder's ExtraPlacement. The README fraction counted every held core file, including those a platform cannot place or that a same-named packed file hides. It now counts what the pack holds.
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.
Profiles, the wiki, comments, docstrings, command output and schema descriptions carried em-dashes, clause-joining semicolons, unicode arrows, box-drawing banners and check-mark glyphs. Each sentence was rewritten rather than having its character swapped. Hashes, paths, source_ref values and every cited file:line are unchanged, which a comparison of each parsed profile against the previous revision confirms.
validate_pr comments now say PASS and FAIL in words, and source_ref values in a profile's structured blocks render as code. test_prose_style fails if any of these comes back, in tracked files or in the generated site.
LRPS2 declares only <bios>.bin, so its emulator pack shipped no PS2 BIOS. The images in the folder another PS2 profile proves by hash, of the declared size, now take the placeholder's place in the pack and in verify.
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.
A test isolated the extra collection by patching
resolve_platform_cores on packextras with create=True, while the
module imported it inside the function, so the real resolver ran.
The import is now module level, the test checks its stub was called,
and no test may create the attribute it patches.
Emulator mode reduced region groups without knowing which files the
collection holds, so a requested-region image nobody had collected
withdrew the held one and left the slot empty. Platform mode already
kept it; both emulator readers now pass the database.
The platform's files and the core extras for the Master System sat
in two region groups, sega-master-system and sega-mastersystem,
reduced apart. A US pack kept the declared Japanese BIOS. A core
extra's system group now takes the platform's spelling, in the pack,
the report and the installer's manifest fields alike.
The name step only ranked archive copies by members declared
through archive sub-entries, and the contents an archive entry lists
never reached the resolver, so the first copy indexed won. contents
now ranks copies by crc32, or by member name where the code opens
by name, and the report and both extra passes carry it. With no
layout declared, a primary holding every ROM of the others wins;
two revisions keep the index order.
Region filtering ranked every declared file, held or not, so a request
answered only by a missing file dropped the held fallback and emptied
the slot. Only held files now decide what gives way; the missing better
match stays reported.
In existence mode the builder packs a core's file at a destination the
platform declares and does not hold, and counts the declaration met.
verify now reads the same placement and reports it OK, so both sides
agree on the platform's count.
hypseus-singe asks for gamecontrollerdb.txt by name alone and, first
in profile order, took the BIOS root of Batocera, RetroBat and
RetroPie with C-Dogs' small table while Solarus pins its own by sha1.
A destination two cores claim now goes to the one naming its content.
