I was originally running Mame by itself through Launchbox and for some reason only half my games would work. So I decided to run it through retroarch since I was already running SNES, NES, Atari etc. The Mame games run perfectly in retroarch using the Mame 2010 core, but when I try to play a game from Launchbox it doesn’t do anything. I have the associated platform as Arcade and the correct core to match but nothing I try is working. Like I said NES SNES ATARI GAMECUBE N64 all work perfectly in Launchbox from Retroarch so I’m not sure why Mame isn’t.
