A cartridge that supplies Bluetooth functionality to the DS? Why, you ask? Well, I asked the same question when I saw this, and there is no certain answer. But the fact is that the DS is a versatile, well-documented device that is used for more than just playing games. Putting Bluetooth functionality in there just makes it that much more useful.

How about a wireless headset for your DS? Or maybe streaming homebrew ROMs from your computer? The implications of this device are staggering. Well, that’s a bit of an overstatement. It might be handy for some, let’s just leave it at that.
