For what it's worth, apparently the Japanese DS Demo Kiosks do not work with non Japanese DS systems. Brandon Piltcher writes: "I took my American DS to the booth, and it gave me the option to download Mario Kart demo and a Dragon Quest demo. I had a good connection, but when I went to download, the connection dropped out... After a few times, I got help and according to the store employee, [kiosks] wont work with non Japanese DS systems."
Regional coding is pretty standard with electronics, but could a truly international DS have a place? Bummer if you're going to Japan with an American DS, but hey, you're still in Japan.
