In this post, you will find the Gameshark & Codebreaker cheat codes for Metroid Fusion [USA]. For those of you playing the game on an emulator, all you have to do is go to your emulator’s toolbar and look for a Cheats section to add and enable the cheat list you want.
On the other hand, if you still play the game on a physical Nintendo Gameboy device, you are going to need to purchase a Gameshark device to enable either the Gameshark or the Codebreaker cheats.
Also, note that when using a physical device you first need to enter the Gameshark or Codebreaker master codes available on the lists below to enable cheats.
Metroid Fusion is an action-adventure game published by Nintendo for the Game Boy Advance handheld console in 2002. It was developed by Nintendo Research & Development 1, which had developed the previous game in the series, Super Metroid.
