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.

Mini vMac 37.03 (setup/SPBASDEF.i:21-24), maintained from Paul C. Pratt's
|
|
code (setup/SPBASDEF.i:30). The emulated model, the ROM name, the ROM size
|
|
and the accepted checksums are fixed when the setup tool writes the build configuration, so one binary runs
|
|
one model. The default model is the Macintosh Plus (setup/SPBLDOPT.i:101,108).
|
|
The entries below describe a build with -m Plus, which is also the default.
|
|
|
|
The setup tool names the ROM after the model (setup/SPCNFGAP.i:28-63):
|
|
Twig43.ROM (Twig43), Twiggy.ROM (Twiggy), Mac128K.ROM (128K),
|
|
MacPlusKanji.ROM (Kanji), MacSE.ROM (SE), SEFDHD.ROM (SEFDHD), Classic.ROM
|
|
(Classic), PB100.ROM (PB100), MacII.ROM (II), MacIIx.ROM (IIx) and vMac.ROM
|
|
for 512Ke and Plus. ROM sizes per model are set at setup/SPBLDOPT.i:3229-3257
|
|
and the per-model checksums at setup/SPCNFGAP.i:81-126. A build for another
|
|
model reads only the name of that model.
|
|
|
|
The SDL backend (-api sdl, sd2 or sd3, src/OSGLUSDL.c) looks for the ROM in
|
|
this order (src/OSGLUSDL.c:606-620): the path given by --rom or -r
|
|
(src/OSGLUSDL.c:4962-4968), the directory given by -d or else the directory
|
|
of the executable from SDL_GetBasePath (src/OSGLUSDL.c:576-604,5185), the
|
|
mnvm_rom folder under SDL_GetPrefPath("gryphel", "minivmac")
|
|
(src/OSGLUSDL.c:546-573,5187), then the working directory. The executable
|
|
directory and the preference folder are searched only on SDL 2 and later
|
|
(src/OSGLUSDL.c:67-72). The default Linux backend is X11
|
|
(setup/GNBLDOPT.i:1609-1621), which searches the command line path, the
|
|
executable directory, ~/.gryphel/mnvm_rom/ and the working directory
|
|
(src/OSGLUXWN.c:957-1022).
|
|
|
|
When no ROM loads, the emulator keeps running and waits for a ROM image
|
|
dropped on its window (src/OSGLUSDL.c:470-483,620).
|
|
|
|
At startup the SDL backend mounts disk1.dsk to disk9.dsk from the executable
|
|
directory, stopping at the first missing one (src/OSGLUSDL.c:486-540). These
|
|
are user disk images.

Macintosh Plus ROM. LoadMacRomFrom reads kROM_Size bytes, 131072 for the
|
|
Plus (setup/SPCNFGGL.i:73-77), and rejects a shorter file. ROM_IsValid
|
|
then compares the first long word of the image with the three Plus
|
|
checksums 0x4D1EEEE1 (v1), 0x4D1EEAE1 (v2) and 0x4D1F8172 (v3), and
|
|
recomputes the sum of the 16-bit words from offset 4 over 131072 bytes,
|
|
which must equal the stored value. A ROM that fails either test is
|
|
refused. The -chr 0 setup option compiles both tests out
|
|
(setup/SPBLDOPT.i:3288-3311, setup/SPCNFGAP.i:128-130,
|
|
src/CONTROLM.h:1309-1310).
