Everything is working fine with LaunchBox and several other RetroArch cores I've tried (Genesis, SNES, NES, etc), they all launch right away as expected.
I read another thread talking about the name difference (medfen vs Beetle) between LaunchBox and RetroArch shouldn't have any effect, but it seemingly does. I've tried all available cores in RA and switching the Associated Platforms core in LaunchBox, but I double click on the game and nothing happens.
Everything works and loads correctly when launching from RA directly.
Is there a config file somewhere I need to change?
Thanks!
