@officialazyria the runcommand just needs to point at whatever folder you want it to look for emulators.cfg in.

I'm seeing that "hikaru" is a Sega system similar to NAOMI and Atomiswave, so it might probably use the Dreamcast setup too, not Arcade. Gaelco is just a game publisher though, right? I don't know much about it but I've got Alligator Hunt running in my Arcade folder under FBNeo. What game(s) are you trying to play? What emulators do they require?
