I bought a Game Cube game to play on my wii (I was searching for this game for a LONG time after my ex sold it off to get some crappy PS2 game years ago) off e-bay but then I found out that you need either a Game Cube memory card or a special Wii one. I found this and now I can save my game (and you can apparently save Wii games on it - save having to use the internal memory or SD card). Great buy, great quality, great price and I received it days before I even got the game (I'd ordered the game three days prior to this order):)
