Each standalone profile records where its version is read: the source at its pin (clk 2026-07-23-136-g9020107, shadps4 0.20.1 WIP, eden v0.2.0-401-g26a03d2), the APK, binary or archive read (kind package), or, where no reading can be made, kind unverified with the reason: a host the tools cannot read, a forge gone or not answering, no build recorded as read, a pin on another branch. Those keep their value, unconfirmed.

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.
