I have had my Super Nintendo for about five years now, and the entire time it has shown a very odd graphical error. It causes the backgrounds in games to move at a slower than normal pace. And in over the top games such as Final Fantasy and Zelda, it completely ruins the textures of the background and makes a shaking motion. Other parts become crooked, and the whole game looks like a mess. Only character sprites and Mode 7 seem to be unaffected by this. Games like Super Mario World and Mega Man X have completely misplaced sprites(Mario World the power up icon in the box at the top of the screen and a assortment of enemies in Mega Man.) I know it is not the cartridges because I have used them in other Snes to a better result.
Since the games are still playable, I have been able to "live with it" for all this time. However, an hour of playing Final Fantasy III(or VI) gave me a serious migraine. So I am fed up with it and am in look of a solution. My problem with is that I cannot seem to find somebody who has experienced the same problem as I am anywhere. On top of that, I have no idea how to word it. So I am completely lost here.
