Thanks. Let me ask you this – I didn’t have a BIOS folder originally set up under the Retropie folder. I tried setting up one on my USB drive from a separate PC and copying the BIOS files in there, but I suspect that solution won’t work. I have seen a few posts from people that don’t have this folder automatically set up for Retropie 3.0 – any idea why the folder isn’t automatically there?

I will look at the video you provided.
