We recently acquired a GameShark v2.1 to use with our N64. We own several old games for this system. We set up Megaman according to directions we found online and entered several cheat codes for that game. We can't play Yoshi's Story which was a factory default with the gameshark. I am suspect if the keycode was changed and is now set wrong. Sometimes the GSP will flash an E or 8 or just be blank when the N64 is turned on. If we turn it on with Goldeneye, the GSP menu will come up and we can play the game.
Can anyone help?
