Would like a Ocarina code for wii to turn off Ko

The ocarina codes are inputted through an app in the homebrew channel. There are codes for other games below

I would like to turn off Ko so I can play a realistic fatal 4 way.

I would also like a Gameshark code to do the same thing for ps2 version of the game
