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.

Marc Rousseau's TI-99/4A simulator at release 0.15.0, the last one with an
|
|
SDL 1.2 front end. RetroPie's ti99sim-sdl1 package builds it from the source
|
|
tarball it mirrors (sha256
|
|
c156674dcb3e40448e84dcfecfe4a16c2bae9df020a79da519d0603cd8ee3b92), adds one
|
|
missing include and runs bin/ti99sim-sdl from its install directory, where
|
|
it links TI-994A.ctg from the BIOS directory.
|
|
|
|
LocateFile (src/core/support.cpp:392-435) tries the bare name in the working
|
|
directory first, then <directory>/<name> under ~/.ti99sim and under the
|
|
install root. The install root is the parent of the bin/ directory holding
|
|
the executable, read from /proc/self/exe, with /opt/ti99sim as the fallback
|
|
(src/core/support.cpp:64-136). LocateFiles (src/core/support.cpp:437-507)
|
|
lists *.ctg in <install root>/console, ~/.ti99sim/console and the working
|
|
directory itself.
|
|
|
|
The console cartridge is looked up by name first and only then by content
|
|
among every *.ctg in console/ (src/core/support.cpp:509-544). The two
|
|
accepted content signatures, 0264512c7d9e7fa091a48e5c8734782ea031a52d and
|
|
16e275faae427465ba4dd4c2bf8569f6546d32dd for console version 2.2
|
|
(src/sdl/main.cpp:533-537), are SHA-1 digests of the ROM and GROM banks
|
|
that cCartridge::sha1 assembles in memory (src/core/cartridge.cpp:248-273),
|
|
not of the .ctg file. A file found by name is used without that check.
|
|
|
|
Device cartridges are picked up by name from that listing: cf7+.ctg and
|
|
ti-disk.ctg are loaded automatically, ti-pcard.ctg only with --ucsd, and
|
|
--no-cf7 skips cf7+.ctg (src/sdl/main.cpp:328-371, 601-604). The .ctg format
|
|
read here is the one 0.16.0 writes: the loaders in src/core/cartridge.cpp are
|
|
unchanged between the two releases.
