EmuELEC, AmberELEC and KNULLI launch standalone emulators by the name
their launch code dispatches on (HATARISA, PPSSPPSDL, FBNEOSA) and ship
32-bit or patched builds of libretro cores under their own .so names
(flycast_32b, mupen64plus_next_alt, genesis_plus_gx_cart_special,
mame0139, flycast-xtreme). Each name joins the profile of the project
its package builds. fceumm_mod reads gg.rom, not gamegenie.nes, and
never opens it, so it gets its own profile.
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.
