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...
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
