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.
RetroPie builds minivmac/minivmac, winterheart/quasi88 and TurtleBazooka/px68k under the package names minivmac, quasi88 and px68k (scriptmodules/emulators/minivmac.sh:12, quasi88.sh:12, px68k.sh:12). With built_by retropie and those names in cores, RetroPie resolves them to minivmac37, quasi88kai and px68k-sdl, while its libretro builds stay reached through retroarch. Measured: RetroPie keeps 532 of 532 platform files OK and gains the 14 files the standalone builds read; no other platform's resolution changes.
The SDL build reads vMac.ROM, fixed at build time to the Mac Plus ROM name and 128 KB (setup/SPCNFGAP.i:60-63), and checks it against three Mac Plus checksums (src/CONTROLM.h:1344-1388). Search order: --rom, the executable's directory, mnvm_rom/ under the SDL pref path, the working directory (src/OSGLUSDL.c:546-620).
