Thanks for the reply Jason. I got antsy last night and deleted the gamecube.cfg and gamecube directories in the export. That was not the way! Everything went haywire after that so I just deleted it all, started a new export, and called it a night. Next time I will try your suggestion.
Great app btw, I have been having a ton of fun setting it up as the heart of my latest arcade cabinet build. I cannot wait for Bigbox on Android!!
