new gcn/wii action replay questions

how can i HACK my new gcn/wii action replay to allow code input?
(NOT FOR ANY RULE BREAKING PURPOSE.)

You can't I don't think. Code input was only available in earlier versions.

are there downloadable channels for wii that do the same thing as an old gcn A.R. iv heard of homebrew but i dont think that does it.

I'm not sure if there is anyway to use cheat codes on GC games with homebrew. I haven't looked into it as I don't own any GC games. I do vaguely remember hearing about some homebrew capable of doing that, but I may be mistaken.

I think Swiss can do that: [code.google.com]

I'm not entirely sure though, and I don't know what state it is in.

Does the old gcn gameshark work on wii? and what is the difference between A.R. and gameshark?
