game shark v3.0
 

i put a code in my game shark, after that my game shark do not work, can i reset all the code or anything
thank you

sry. The Gameshark cartridge is glitchy that way. I had a total of 3 gamesharks. This is what happened to all of them. GS has some kind of disclaimer about using non-official codes. They used to have something where you send in $10 along with your GS cart and they will send you an updated fixed version.
