duckstation.sh quotes its glob, so its copy names a file called * and
installs nothing. userconfig-setup copies /usr/config into
/storage/.config at every boot, an existing file kept (false | cp -i),
and /emuelec links there: that copy installs settings.ini and
advmame.rc. A quoted glob is no install, and a redirection ends the
copy's operands. Rescraped at v4.8: only these installs change.
A launcher record citing a config, option or feature file binds only
when the platform's code installs the file (installs), its launch code
was read for what replaces it (overrides), and the emulator's profile
shows where the shipped build loads it and reads each key
(config_reads, read at pin_build). Unproven records place no file and
hand no directory. verify, cross_reference and the platform page list
them apart, outside severity and --strict.
The scraper reads the start scripts and the configs each package installs at the tag the BIOS list is pinned to: configs that name a BIOS path, the yabasanshiro search, directories handed to DuckStation and the PCSX2 builds, and the ln -s commands that put bios/ where an emulator reads. A package that ships one config per device gets a device field only where the values differ, as melonDS does on AMD64.
