Banjo-Kazooie: Grunty's Revenge Cheats for Gameboy Advance
To obtain N.Kreditzs complete the game and in the ending credits get as many coins as you can in the slide minigame. When the ending credits have finished load the game again and go to Spillers Harbour level and find an Arcade mahine there and you will be able to use the N.Kreditz there to play mini-games that you have already completed.
