@mitu sorry I’m not sure, I switched to bsnes core for K Griffey in the launch menu and that’s when the issue started. I assumed that if KGJr didn’t launch, it wasn’t compatible with the core so I switched back to SNES9X. However I decided to re-image retropie, everything is working now, including KGJr in bsnes (MLB season now works). This was after I removed and reinstalled the core packages to no avail.
