You are exactly right, my "hi" and "nvram" folders are not in the RL folder, they are in Mame. It sounds like it might be time to move everything over to LaunchBox directly, it's just years of Hyperspin holding me back. Thanks!
I'm having an issue getting this setup. I'm running Mame through RocketLauncher instead of straight through LaunchBox, so I think that's my issue. Is there a way to point this at my actual Mame folder?
