Thanks I’ll go through it all again I’m sure it must be something simple I’m missing.

I’m new to launchbox, loaded up retroarch and launchbox with nes roms and a few snes roms too. I followed ETA prime’s videos and I can’t get any games to play. Deleted everything after checking all my settings and file locations, reinstalled and same issues. So just thinking I did some wrong I installed Dolphin via launchbox and downloaded Zelda windwaker rom, and same problem. I don’t get any error messages and the play count goes up but nothing ever happens. Any insight at all would be awesome. Thanks in advance!
