In Goldeneye 007 for the Wii, there is a cheat you can use to change the sprint action to invisibility.
Go to Extras and enter the following code exactly as displayed:
Inv1s1bleEv3ryth1ng
Keep in mind that this code is case sensitive, and only works in local multiplayer games. Once you enter the code, you’ll see it in the Modifiers list when starting a split screen game. Once it’s enabled, press the B button in the game to become invisible instead of sprinting.
