I watched this tutorial:
Action Replay Gamecube App Tutorial for Wii (Cheat on any GC game) (http://www.youtube.com/watch?v=9C2RlcLV9xw#ws)
and When it says its installing the CIOS it freezes [still plays the music the app does] but doesn't install anyone have any newer version of it or something that might help? Everything else in the video worked.
