Kronos reads kronos/stvbios.zip, else stvbios.zip at the root of the
system directory, and a ST-V game stops without either
(libretro.c:1608-1617, 1676-1681 at the pin). The archive under
archive_prefix and the root copy are one need, but only loose entries
could be members, so the required-only pack carried both.
An archive's own entry now joins a set like a loose file. verify
--emulator and the emulator pack settle archive units with the loose
entries, the required-only pick covers them, find_undeclared_files
and cross_reference record them, and the unit under archive_prefix
ranks before the same name at the root. Its members still settle the
archive by their contents. Kronos' stvbios.zip is grouped stv-bios.
No other profile reads one archive under two paths: odin and
tgpulse_next_m1 place their own entries at the prefix path, and
flycast's naomi.zip has one path per build.
Three changes to the search-list model, one commit because the readers
and the profiles must move together for the schema to hold.
Set requirement in a groups map. pom2 falls back on apple2.rom for the
][ and the ][+, and on apple2e.rom for the //e it boots and for the
unenhanced //e: one required on the file could not say both. A profile
now declares groups: {name: {required}}, a member writes no required
of its own (schema and validate_schemas refuse one) and load_emulator_
profiles derives it, true when one of its sets is. group takes a name,
a list, or a map from set to rank where the rank differs per set. pom2
is grouped from SystemProfile.cpp and MainWindow.cpp:246-296 at its pin.
One member per required set under --required-only. The pick is the
first the code reads among the held members the region filter leaves,
by rank then declaration order; a set the platform declares a member
of is carried by that declaration. The emulator pack, verify
--emulator, the platform pack, its manifest and verify --platform read
alternatives.required_only_spares or core_file_spares.
variant_group is now selection_slot: files a core chooses between by
a rule other than first found (disc territory for PicoDrive and
Pizza Boy SC, the o2em_bios option, a WebAssembly probe in SWF
Player). Where the code takes any one, the field became a group:
ARMSX1 (ArmSxBackend.java:149-157, name order), ePSXe (load_bios
0x433540-0x433621 of the 2.0.5 Linux x64 binary, one configured path,
HLE when BiosHLE is set), FPse and FPse-NG, DXX-Rebirth's HOGs
(inferno.cpp:472-512). odin and zesarux carried it with no effect.
slot.py compares ranks only between candidates that share a set.
A core that loads the first of several names (yabause: saturn_bios.bin,
sega_101.bin, mpr-17933.bin) needs one of them. Profiles wrote this as
required on the first name and optional on the others, so verify and
the gap report called saturn_bios.bin a missing required file while
sega_101.bin was held, and a set held only through a name marked
optional read as a need met by an optional file.
Model: an explicit group on the file entry, mirroring the platform
field. priority was not reused: it is a rank, read by slot.py, region.py
and truth.py inside a (system, region) slot, and that slot is not the
set. px68k-sdl ranks its IPL list and its font list each from 1 in one
system, pom2 ranks one list per machine model, DuckStation ranks 105
images across every region and takes any of them. A rank cannot say
where one list ends. priority stays the order inside a group.
Readers, through alternatives.settle_sets:
- verify --emulator and the emulator pack: a held member fills the
set, the others leave the report, a set nobody holds is one gap
under its first member naming the others.
- find_undeclared_files (verify platform, core complement of packs and
manifests): same rule, a platform declaration or launcher counts as
answering the set.
- cross_reference: excused members are set aside as other versions.
- slot.py: ranks compare members of one set only.
- archive members: a required set inside an archive is met by one.
- truth: a member gives no requirement of its own, one_of and
one_of_required carry the set, and the exporters and the diff leave
such a line's required as the platform wrote it.
- validate_schemas: members of a group share required.
