A launcher record citing a config, option or feature file binds only
when the platform's code installs the file (installs), its launch code
was read for what replaces it (overrides), and the emulator's profile
shows where the shipped build loads it and reads each key
(config_reads, read at pin_build). Unproven records place no file and
hand no directory. verify, cross_reference and the platform page list
them apart, outside severity and --strict.
Batocera builds RetroArch with its core downloader (configure defaults,
qb/config.params.sh:149-150), shown in the menu since it is no Lakka
build (config.def.h:743-745), and configgen sets no URL, so the compiled
one applies: buildbot linux/x86_64 or linux/armhf, none on aarch64
(config.def.h:1855-1861). The targets scraper names that list per board
(downloads, an armv7-A CPU read from arch/Config.in.arm), the builder
and the published target lists add it, and the platform names the union
as installable_cores. applewin, gong, squirreljme and vemulator come
back that way. A build option that compiles the downloader out, or a
shipped retroarch.cfg that blanks its URL, turns it off.
The configs root place joins roms and emulator folders in the split
handed directories, and RetroBat's portable folder table keeps both
sides. Batocera, KNULLI and RetroBat records regenerated.
RetroBat passes XRoar -rompath bios/coco for the coco system, and its
es_features offers the CoCo 3 machines there. The per-system record now
carries those machines (machines:), and an entry whose name the
platform list does not declare is launched for the system offering
its own profile system as a machine, by _norm_system_id. coco3.rom and
coco3p.rom move from bios/dragon to bios/coco. RetroBat offers no
MC-10 machine, so the mc10 ROMs keep the default bios/dragon.
Batocera and KNULLI start shadPS4 from CONFIGS/shadps4, so its user
folder sits below /userdata/system/configs. The scrapers read that root
from batoceraPaths and write configs_root with its source_ref. The
manifest names it configs_directory, and install.py honours it through
the same checks as roms_directory: character rules, at most two ups,
the ancestor match and the lexical bound.
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.
A launcher record can name the systems it is written for, and then
replaces there what the records naming none hand: RetroBat passes XRoar
-rompath bios/coco for coco and bios/dragon otherwise. An entry is
launched for the systems it names and those the platform declares a
file of its name under. A {system} search_dir gives one directory per
platform system, a colon search path each of its directories.
standalone_pools names settings a program reads as a list of
directories, each searched like a layout subfolder (openMSX filepool,
XRoar rompath). Any entry serves: the one the platform list fills
comes first, then the first of the BIOS tree. A handle above a
declared directory lands it where its link points (configure
--prefix). Record order now survives the standalone set.
A copies record names its files under search_dir, the folder the code
copies from, and passes_to is the target, as the schema and RetroPie,
RetroDECK and AmberELEC already write it. KNULLI listed patches.zip
under the BIOS folder it is copied into, and KNULLI and RetroBat wrote
the target as prose with the condition. The condition of a copy now
goes in depends_on_option. Only launcher records change in knulli.yml
and retrobat.yml.
emulatorLauncher 228731e0 lists ten PS2 BIOS in one group: one held file
is enough and Program.cs reports the others OPTIONAL. The scraper keeps
group and optional, verify and the pack check apply the same rule.
batocera.linux 6b08b873 lets a biosFiles item declare its md5 as a
list of strings, and checkBios accepts a file matching any of them.
The scrapers join the values with commas, as for Recalbox, and record
md5_list so the export writes the list back as a list, byte for byte.
EmuELEC's ports system has one emulator, `ports`, the dispatch to a
script ports.yaml generates. The scraper now reads each port's engine
(the libretro core handed to emuelecRunEmu.sh with -C, else port_exe),
so devilutionx, sonic2013, soniccd, sonic-mania, reminiscence and
rigelengine are examined. Standalone emulators keep the spelling the
launch code dispatches on instead of invented lowercase forms, and
media players and runtimes go to the overrides' remove_cores.
Each system of the AmberELEC, EmuELEC and KNULLI lists now carries the
cores its ES list offers it, in menu order, under `cores:`.
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.
Each OS publishes Batocera's systems dict (knulli-systems, and
batocera-systems at AmberELEC's newest prerelease commit and EmuELEC v4.8),
read with the shared parser. Cores come from each OS's own ES list.
AmberELEC and EmuELEC declare neogeo/ and ports/ beside bios/ from
/storage/roms, so their packs extract there and core_destination puts
core files under bios/.
The Required packs and manifests carried every data tree, the FreeIntv
overlays included. A data_directories entry now accepts required: false,
and the platform, emulator and manifest walks leave such a tree out under
--required-only. FreeIntv reads its overlays only with the multi-screen
option and draws a placeholder keypad without one (src/libretro.c:294-296,
350-369).
The scraper walks each package's functions the way RetroPie runs them in one shell (assignments, arrays, for loops, brace expansion, $md_id, calls into other packages) and records every link, copy, move and setting that names $biosdir, the addEmulator flags (sdltrs -romfile3), the BIOS read outside $biosdir (basilisk --rom, gngeopi -B) and the launch scripts that exit without their file (fs-uae kick13.rom, reicast dc_boot.bin).
Each package also gets a package record with its rp_module_repo and the systems it registers, which maps a package to the build it compiles. The schema gains package, repo, systems and the moves and package kinds. platforms/retropie.yml is regenerated at 46128cd2: only the launchers section is new.
The scraper reads the start scripts and the configs each package installs at the tag the BIOS list is pinned to: configs that name a BIOS path, the yabasanshiro search, directories handed to DuckStation and the PCSX2 builds, and the ln -s commands that put bios/ where an emulator reads. A package that ships one config per device gets a device field only where the values differ, as melonDS does on AMD64.
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.
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.
RomM's verify_file_hashes compares the size, then md5, sha1 or crc. We
compared md5 alone, so a fixture entry with one mistyped hash was left out
of the pack RomM would accept it from. The rule is declared in romm.yml
and read by verify, the builder and the manifest.
JSON Schemas for the database, install and pack manifests, target
manifests, site API envelopes and stats, plus the semantic invariants a
schema cannot express: declared totals matching their lists, no
destination both installed and omitted, database keys matching their
sha1. validate_site.py checks the rendered HTML for metadata, headings,
image alternatives, duplicate ids and unresolved local links.
Pack manifests are read from inside the generated archives, where
generate_pack writes them, rather than from a dist/ glob that matches
nothing.
Emulator and platform schemas gain additionalProperties: false, and
cores[] plus contents[].name must be strings: an unquoted 81 or 01 in
YAML parses as a number and stops matching the upstream name.
