Only games from the Online Amiga Game Database will currently appear in FS-UAE Arcade. If you don’t see any game entries when starting the Arcade, please make sure you have enabled the game database in FS-UAE Launcher (logged in).
FS-UAE Arcade will probably support browsing / launching locally created configurations as well, but current focus is to make it work as well as possible with the online game database.
