I was looking into input-style DS accessories, and stumbled across the game, Pokemon Typing Adventure. If you take a look or give it a Google, you'll notice that it is companied by, logically, a keyboard. A bluetooth keyboard. "But Grebbles," you say. "How can this be? The DS doesn't have bluetooth!" No. No it doesn't. But this game is in fact marketed for the DS. And it is in fact accompanied by a bluetooth keyboard. This leads me to believe that there is a bluetooth module inside the game cartridge, or the keyboard has some other wireless interface with which it can be used with the DS. Almost definitely the former of the two. Anyway, I was wondering if what remains of a homebrew scene has managed to do anything with this. Any documentation, teardowns, etc? And if not, anyone interested in bluetooth for their DS? I'm considering buying the game and opening it up to see what's what.
