This thing is known in other circles as a "NOAC" device, which stands for Nintendo on a Chip. It's also known as an FC Computer, or FamiClone since it's a clone of the Nintendo Famicom. These are quite common, but for almost $50 you're getting ripped off. Yes, it's a pirate device, and no it's not really a computer and has no computer like functions unless you have the Famicom Basic cartridge. On the Benheck.com forums which I frequent people like to use these and gut the parts out to make a portable Nintendo.
