Hyperkin Smartboy

Playing Game Boy games on your iPhone has been possible for a while, if you were lucky enough to grab a sneaky app or just jailbroke your device. But you've never been able to do it like this. Still in the development stages, the Hyperkin Smartboy promises to wrap your phone in a highly familiar body, complete with physical controls and a slot on the back for playing real cartridges — which might be enough to make it App Store-friendly. Whatever the case, you can rest assured it'll be a must-have for any nostalgic iPhone owner if/when it finally comes out.
