The profiles written for RetroBat and RetroPie were checked the same way: UZDoom, LZDoom, SRB2 and AdvanceMAME data ship with their releases, RetroPie installs the shareware Doom, Quake III and Wolfenstein data, the Aleph One scenarios and 4DOS beside the ports it builds, RetroBat installs Jynx's ROMs, and Recalbox's uae4all core comes without the AROS ROMs.
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.
