This pocket sized portable system takes its inspiration from the Game Boy Advance. It folds in half like a 3DS, and measures just 8 x 8 x 4cm. It’s built on Raspberry Pi A+, with software that allows you to play an unlimited number of NES roms. Its shell is made from American walnut. The tension of the hinge can be adjusted with a small screwdriver. There’s no word on whether or not this gem will ever go on sale, but we’d imagine there’d be some sort of legal battle over the inclusion of so many roms.
