Do you know how much the bits cost and where I can get them? I might even try the magic eraser before doing anything that requires me taking the game apart. Does anyone know what that cause of this problem is from (such as dirt, dust, finger prints etc)? I was told also to try getting the special screw driver to open the games and clean them out completely, would that be a good thing to do? Sorry for so many questions guys, I am new to the whole cleaning cartridges thing even though I grew up in the NES generation lol. But thank you guys for all the advice you have given so far
(popcorn for you guys for all the help lol).
