Emulationstation 1 had the switch -gamelist-only. Doesn’t seem to work in EmuStation 2. Looked after it myself but no solution so far for me. But I cleared out all the clones anyway while sorting the roms. I think I have only SFIII and one other game that need to have a second rom to run. I can live with that.
