So I worked on Pineapple 64. I have a stupid bright spot at the upper left corner of the screen. It flickers once and then goes away. But it happens again if you go to a different screen. I don't know why. I guess I'll just have to leave it in the game because I tried every possible thing I could think of and nothing removed it. And it only happens on real hardware and not Mednafen. So I'm angry right now.
