yes, you have to buy it though and it is pretty useless, no flash support, only basic images supported etc.
I can read some japanese. An intersting point is that the DS download service is used (the same one as for single card multiplayer).
There appears to be something involving the stylus, a "toriningu" (no idea what that is, it's a mangled English word though) and an adult's "toriningu".
If anyone can think which English word "toriningu" sound like, it would help.
Edit: "kuredito kardo" is credit card in japanese, that is an example of a loan-word, "toriningu" is also a loan word.
