Play real Game Boy carts on your phone!
The Smart Boy, as it has been called, will even take Game Boy and Game Boy Color cartridges and play the game right on the screen, with the best part being that you get actual physical buttons to use rather than terrible touch controls.
It all started out as a concept by Hyperkin Lab and they've somehow managed to make it a reality. The device isn't quite there yet and is still being called a 'Development Kit' in the hope that folks will buy one early and help improve the code for other users. In return, they'll get a percentage of the profits made from the sale.
