Help with Crash Nitro Kart cheats

[snarkel]

With a few google searches I found some AR codes for Crash Nitro Kart. Specifically, a master code and an unlock everything code. None of them work though, im not sure if I have the wrong dolphin/game version or if im just doing something wrong. Could someone help figure this out or supply a working unlock everything code for this game?

Im on Dolphin 5.0
Crash Nitro Kart USA version revision 0
These are the current codes im trying to get working

Sorry for the second post on here
(As dumb as it sounds I could not find an edit button)
But if no fix or other cheats can be found, is it possible to download save games or save states? If so, I'd also be happy with one of those with everything unlocked.
EDIT: I forgot to mention that apparently this game has an unused voodoo doll item and that it can be re-activated with cheats. Anyone know said cheat?
