I'm guessing it would work with the American games, because I
do have the American cards? They're in English, so they're the American ones, right? Haha. Well yeah, of course.
I really want the DS game for it, but I'm not sure if you actually need totally different cards for it. I heard the 'arcade ones' won't work for it, you need to buy ones made specifically for the DS.. I'm not sure though, but it has something to do with the bar code scanner that you plug into your DS.Okay, the one I'm seeing sold on the net works with arcade cards, but only the Japanese versions
So to play it, and if you're not in Japan, you have to buy them on Yahoo! Auctions or just find a way to get cards from Japan.
