There’s a lot of tech that went into this as you can see, based on the layout of the device, they basically eliminate the C-Buttons and create a duel-stick look to the console. The right stick serves as the replacement for all of those yellow buttons as you just have to do the direction you need. As for the rest of the controls, one of the chips has been replaced with a standard Nintendo control system, so the Nintendo 64 controls operate like any other standard gaming device. It’s a cool little piece of tech to look at as there aren’t a ton of people out there making custom designs for old-school consoles that are this sleek and compact. Even the 3D printing on this one is pretty solid as there are no wasted materials on here and it is made to be about as small and portable as you can get it. You can check out the video below in which he goes over how he went about making the device.
