Hey guys, my friend gave me his Gameshark, asking me to try to fix it because it doesn't work. And I've tried a few games and it still won't boot. I get the 8. when it boots, with a black screen. Does a certain game need to be used to re-activate the 'shark? He says that Griffey Baseball (the original) and Diddy Kong Racing are the games I need to re-activate it. Both of us don't own either. You think there are other games that can be used to re-activate it? BTW, this is GameShark Pro.
