RetroBat's generators create user/ beside yuzu.exe and eden.exe and
portable/ beside Ryujinx.exe, which the emulators read in place of
%APPDATA% (PORTABLE_DIR, Ryujinx AppDataManager.cs:12, 60). Their keys
now go below emulators/<key>/.
yuzu, eden, Ryujinx and Azahar declare the data directories their code
reads, so EmuDeck's links place their keys in bios/<emulator>/keys and
leave the 3DS NAND files it links nowhere named, not at the BIOS root.
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.
Each name is attested by a buildbot .info file, a hardware target core
list or an ES-DE find rule. Two of them resolved to no profile at all:
dosbox_staging, declared by Batocera on three targets, and
freeintvtsoverlay, shipped as FreeIntvTSOverlay_libretro.info.
vba_m keeps no cores list: no upstream calls it that. It is a legacy key
folded into vbam, which already carries the buildbot name vba-m.
