Captain NvsS

To be fair, it does come bundled with the game. I don't think it costs money separately, and I really don't think that the old ones will work with the DS. And Nintendo is probably (and by that I mean hopefully) not going to be stupid enough to sell the thing on it's own. Plus, a lot of people don't have the old version, like myself. (Ages of using Pokemon Stadium 2 to get all my mystery gifts)
