Ever since video games made the jump from arcades to living rooms (as well as our hearts), people have always talked about how awesome it would be to take our favorite games on the go.
Nintendo was the first company to hit major pay dirt on this concept, introducing the Game Boy portable console in 1989. The console went on to sell nearly 120 Million units worldwide, and kicked off an entire line of portable systems for the company. This ultimately led to other massive successes like the Game Boy Color, the Game Boy Advance, the Nintendo DS, and the Nintendo 3DS.
While these portable systems are all amazing, it hasn't stopped plenty of tech-savvy gamers and third-party companies from making their own custom systems, which can often do things that the official ones can't.
Things like a portable Nintendo 64!
Or a portable Super Nintendo!
While all of these are great, a modder named Vincent Buso has made something that pretty much puts all of them to shame; a functioning Game Boy that you can clip to your keys.
