So I was testing the same game on both mgba emulator and injected GBA VC to see how well they running. My injected VC was working pretty fine, however after using mgba now it bugs my other injected GBA VC. Now my GBA VC has display issues (see pics) and I tried re-inject VC, reboot, reinstall...but the game still bugs. I'm pretty sure it is mgba caused the issue, as they were fine until I used mgba then it corrupted the display setting of my VC. I was wonder if anyone could help, thanks!
