I installed some custom GBA cias on my N3DS (on 11.4.0-37U), specifically Pokemon Fire Red and Emerald. First couple of times I played them they worked. Now when I start them up, they stay on a black screen and don't load. I tried uninstalling them and reinstalling them, no change. I installed other GBA games to see if they had the same problem. Yup. Can anyone help me out?
