Hey that's a good idea, since I ran out of room on my Wii system memory a long time ago, I already back up the games I don't play that often, but I never thought of backing them all up. I mean it can't be any more hassle than actually switching cartridges, cables, channels etc to swap NES games to Genesis games, etc. I even bought a 1GB Sd card just for my Wii. Ok I lied I got it for Christmas but that is the reason why I asked for it in the first place.
