I recently purchased a Banjo-Kazooie NOT FOR RESALE cartridge from a bookstore and I was hoping to use my Gameshark to see what I could uncover, but it seems to require a key code due to the fact that it will not boot on the Gameshark. I tried using the Banjo-Kazooie key code but it didn't work. I saw that users can input a custom key code into the Gameshark so is there any code for NOT FOR RESALE carts? Or is there a way to find the key code myself? Thanks!
