Has there been any gecko ocarina codes knocking about for the single player game? I see the New Super Mario cheats are out and it was released after Modern Warfare?

The only reason I ask is not to cheat online before anyone ecuses lol.
But Ive been playing the single player campaign on my Girlfriend's brother's wii and got really far only to realise that because the geme can be played online I cant use save game extractor! (something to do with the individual friend code i belive?)

So just tneed the cheats to stroll through the levels ive already completed.

Anyone know where to find them?
