Possibly the single most ’90s piece of technology ever invented, the Nintendo 64 marked the last time anyone ever thought that game cartridges were cool in a non-retro way, and also marked the last time any videogame company designed a controller specifically for three-handed gameplay. It also gifted a generation of players with some of the best games ever made: Perfect Dark, Mario 64, StarFox 64, Shadows of the Empire, and freaking Wave Race. And now, someone has created a prototype for a portable Nintendo 64.

You can watch it come together in the video below. Note how designer Bungle announces the device’s artisanal sensibility by specifically playing The Legend of Zelda: Majora’s Mask instead of Ocarina of Time.
