100 emulator names the two platforms run had no profile, so their packs carried nothing for them. Each was read from the platform's own launcher or scriptmodule: the same program as an existing profile takes the name in cores:, a different build gets its own profile read from that version, a launcher or self-contained game goes to remove_cores, and the rest are new profiles written from their source or shipped binary. The files they need that the collection lacked are collected from the upstream distributions. Bungie and splitwolf trees are read by path and stay out of dedup.

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.
