We here at EoFF dissaprove of cheats and offer no advice on how to use, find, or create them, therefore I believe this thread will most likely be closed shortly after this post.( I think)
Are you sure you aren't mixing that up with links to illegal downloads?

Anyway, you need a cheating device called a 'Gameshark' to use these codes. I don't know much more than that, because I don't have any cheating devices. Sorry.
