If you've always wanted to carry around a familiar handheld system but play all of your favorite Super Nintendo and Sega Genesis games, there's a genius for you to meet.

I've got so much admiration and respect for people who are capable of modding things. No matter what it is, the ability and inclination to just pull something apart and fiddle with the insides of it until it becomes something completely different is awesome. And when it lets you play retro games that you've always loved while sitting in a doctor's office or at the DMV or whatever? Well, that person is nothing short of a genius, a scholar, an icon.

That's the case in this video, as this guy spent some time modding a Game Boy to work with SD cards, enabling the use of emulators that let you jump from NES to SNES to Genesis and back again. All in one unit.
