I have an original PSP that I like to play the old school games on however on certain games they act up like Super Mario World I can play fine until I get to the boss door in the castle and when I go in the screen turns red. and a similar action on Link to the Past, it plays fine until I view the map. It has not always done that, it just started and I have tried different emulators as well as different roms. With the same result. Any thoughts.
