Black Screen

[Reels]

Hello - I just got set up with Launchbox and Retroarch and when I go to play a game I can hear it, but the screen is black. Opened Retroarch and I can see and hear the game. Seems like a Launchbox issue. Any ideas?

When this happens can you hold alt down and press tab (leave alt held so the UI doesn't disappear) so see which window is displaying the black screen?

I actually noticed the core I chose through RA wasn’t the same one I had picked in LB. Once I matched it, boom. Thanks!
