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.

ColecoVision and Coleco Adam emulator by Marat Fayzullin, published as
|
|
versioned archives on a personal site rather than a repository. The 5.6
|
|
source archive carries the portable core (ColEm/, EMULib/, Z80/) and the
|
|
Unix port. Windows and Android builds are binary-only.
|
|
|
|
Three system ROMs are read by StartColeco (Coleco.c:266-300) before the
|
|
hardware reset and before the cartridge. Lookup runs in the directory
|
|
named by -home, which main() defaults to the directory holding the
|
|
executable (ColEm.c:66-72), so the ROMs sit next to the binary the way the
|
|
official archives ship them. Each name is passed to fopen as written, in
|
|
uppercase.
|
|
|
|
COLECO.ROM is fatal. A failed open or a file yielding fewer than 8192
|
|
bytes sets the error string, and StartColeco returns before ResetColeco
|
|
and RunZ80 (Coleco.c:306). It is loaded in both modes and maps at 0000h
|
|
on the ColecoVision and under the Super Game Module (Coleco.c:651).
|
|
Nothing in the tree substitutes for it.
|
|
|
|
WRITER.ROM and EOS.ROM gate Adam emulation. Each has to yield its full
|
|
read to advance the AdamROMs counter, EOS.ROM is attempted only once
|
|
WRITER.ROM succeeded, and Coleco.c:300 collapses the counter unless both
|
|
landed. ResetColeco then clears CV_ADAM when the counter is zero
|
|
(Coleco.c:749), so -adam falls back to ColecoVision, and inserting the
|
|
first disk or tape into drive A: is refused (Coleco.c:1454, 1460, 1496,
|
|
1502). SmartWriter maps at 0000h on boot and EOS at 4000h once port 20h
|
|
enables it (Coleco.c:628-646).
|
|
|
|
No hash or magic number is checked on the three ROMs: the read length is
|
|
the only gate. CRC32 is computed for cartridges alone, feeding the
|
|
GuessROM hardware heuristics (Coleco.c:482-486).
|
|
|
|
Cartridges, .DSK/.FDI disks and .DDP tapes are user content. Beside a
|
|
loaded cartridge, FindState (Coleco.c:1529-1548) probes <name>.sav,
|
|
<name>.sta, <name>.cht and <name>.pal, and StartColeco tries the palette
|
|
file named by -palette, defaulting to ColEm.pal (Coleco.c:75, 327-332).
|
|
Those are written by the emulator or hand-authored, and ChangePalette
|
|
supplies one of three built-in palettes when no file is found
|
|
(Coleco.c:324, 543). Console fonts are compiled-in arrays (Console.c:46,
|
|
130), and LoadPNG (Image.c:1230) sits behind an undefined LIBPNG guard
|
|
with no caller.
