The Sims: Castaway Wii multiple saved games

So after purchasing The Sims: Castaway for my wife we quickly discovered you can only have one saved game at a time! Why makers of video games would ever do this I don't know! Anyway, I have discovered a way to have more than one saved game at a time. To do this you must have at least 2 SD cards. You don't have to get the ones that Nintendo sells at wal-mart, go online and get them cheap. Now insert one sd card in the wii and transfer the saved game to it. Now create a new game, save it and move it over to the second sd card. Now when you want to play one game transfer it to the wii and continue the game. when your done transfer it back to the sd card and load the other sd card. I'm not sure if it's possible to use the wii mote to save games or not. I'll try it and post back my findings.
