Hyperkin is the company behind the RetroN series of consoles, which can play cartridges from all manner of classic systems - like the NES, Super Nintendo, and Mega Drive - on a single machine with upscaled graphics and enhanced audio. And for its next feat, the company will turn your iPhone into a proper Game Boy.

We’re not talking about a case that just makes your phone look like a Game Boy from the back, or even a jailbroken app that emulates the old handheld classics. No, the SmartBoy is a controller shell that takes in your iPhone 6 Plus - and lets you use its screen to play the Game Boy cartridges plugged into the back.

April Fools, right? It’s not, says Hyperkin - but it almost was. See, the company devised the device as a would-be prank, but then realized there was real value in making it happen. ThinkGeek has done similar things in the past, turning a popular joke item into a real one as demand surfaced.
