Hi guys, I’m new to all this. I’ve set up launchbox first with NES and Retroarch. Games have all gone in but when I try and play. Only the background comes up with music or Sometimes a small window comes up but I can’t play games. In big box mode it goes to play then goes to black screen. I’ve searched high and low trying to figure it out but can’t. Any help would be great? I’m using Nestopia. I followed ETA primes videos for setup. So I think I did right.
