Summary: It doesn't mention anywhere that this is Version 1.2, and that you CANNOT add codes beyond what is preloaded on the disk. Having experience with AR for Nintendo DS, I was expecting to be able to add codes or at least have some codes present for the game which I intended to use this (Phantasy Star Online). It does work, and for most games will be all you need. Just wish this point was mentioned somewhere before purchasing.
Summary: This thing is bad. It only worked for a week,then it started freezing my gamecube.Then some of the cheats would not work.And worst of all, it deleted all my memory data on my memory cards. It also messed up one of my favorite games.I suggest to all, NEVER BUY THIS ITEM!
