Seems like it started working after I tried to start a Gamecube game. I somehow ended up in the actual dolphin emulator menu and now it works fine.

@acris Recalbox-x86_64 - 7.1.1-Reloaded

Hi! For the past two hours I've been trying to setup a few WII games on recalbox. After finally finding a way to transfer them to my recalbox, they won't run. I keep getting a 'bad rom/missing bios files' error. I've tried looking through existing posts but didn't find an answer. (The roms work perfectly on dolphin on my main computer, which is why I'm confused.)
