It was just an April Fool's joke but because so many responded so positively, it's actually happening for real.
Game accessory manufacturer Hyperkin offered up the bogus "Smart Boy" announcement this past week, which allowed your smartphone to transform into a Game Boy Color.
Well, it wasn't real at the time but as it turns out, Hyperkin was just testing the waters. And as they said on their Facebook page :
"A lot of you were speculating that the Smart Boy is an April Fools' Joke. Well, it sort of was. We 'leaked' it with the initial intent of testing the market, seeing whether or not it should be something we'd actually make, under the guise of an April Fools' Joke.
Looks like you awesome folks ACTUALLY WANT IT, so the Smart Boy is now in development! Thank you all for your enthusiastic responses!"
All you have to do is plug your iPhone 6 Plus (and other smartphones in the future) into the Smart Boy and you can play any Game Boy and Game Boy Color cartridge you please. You get the good ol' familiar buttons and you can expect gameplay to last for up to 5 hours thanks to the Smart Boy's built-in battery that can be charged by the phone.
What you're seeing here was the image released with the "joke" and it was only conceptual. However, the real thing might end up looking just like that. Sweet, huh?
