Each platform's own packages were read at the revision our data pins, for every emulator and core it ships: Batocera, Recalbox, RetroPie, ROCKNIX, Lakka, RetroDECK, RetroBat and EmuDeck. Files a package installs where the emulator reads them are recorded with installed_on, and files a release bundles but a package leaves out with not_bundled_on, so each platform's pack brings what its users lack and nothing they already have. The standalone profiles never checked before were held against their releases the same way. Batocera's imame4all is the mame2000 core. The primary neogeo.zip was a 7.7 KB placeholder no platform pins and no pack served: removed, the real dumps stay in .variants.

notes: |
|
|
Nestopia UE is a cycle-accurate NES/Famicom emulator. The libretro port
|
|
tracks the upstream Nestopia JG project. NES cartridge games need no BIOS.
|
|
Famicom Disk System games require disksys.rom (8 KB FDS BIOS) in the
|
|
system directory. The core validates the BIOS via CRC32 against two known
|
|
dumps: standard Famicom (0x5E607DCF) and Twin Famicom (0x4DF24A6C). An
|
|
unknown BIOS triggers a warning but still loads.
|
|
|
|
NstDatabase.xml is an optional game database for region autodetection,
|
|
mapper selection, and 4-player adapter recognition. A copy is baked into
|
|
the core binary (libretro/nstdatabase.hpp) as fallback. The upstream
|
|
Nestopia JG requires this file, while the libretro port makes it optional.
|
|
|
|
An optional custom palette file (custom.pal, 64 RGB triplets) overrides
|
|
built-in palettes when the nestopia_palette core option is set to Custom.
|
|
The libretro port embeds all named palettes (Royaltea, Smooth FBx, etc.)
|
|
that the upstream loads from external .pal files.
|
|
|
|
Five Famicom games use external ADPCM audio samples placed in
|
|
system/nestopia/samples/{game}/ as numbered .wav files. These originate
|
|
from MAME sample ZIPs. Games function without them but miss some audio.
