Over the years, gadgets have of course transitioned to become smaller and more compact. In following suit, YouTuber Vincent Buso has recently made what is essentially a keychain-sized Game Boy.

Dubbed the Keymu, the console has four buttons and runs ROMs courtesy of an Intel Edison chip. Boasting two more buttons than the original Game Boy, this in turn allows you to play Sega Genesis and some Super Nintendo games.

And if you'd like one of these insanely small "Game Boys" for yourself, you can try to build your own courtesy of these detailed instructions.

So, who wants one?
