Demand for the Nintendo's nostalgia-driven NES Classic Edition has been so high that the company and retailers have had trouble keeping up with the demand. If you can't get one, you may want to consider creating one of your before you pop on eBay and drop a couple hundred dollars.

ArsTechnica got tired of waiting and did just that, realizing that at its heart the NES Clasic was a "just a little Linux-powered board inside a cute case." The site proceded to build on, using a Raspberry Pi 3 Model B, a Samsung 64GB EVO card, a Raspberry Pi 3 case, and two Buffalo Classic USB game pads. Once completed, they called it a RetroPie Classic Gaming Box, with the capacity to go beyond the limited 30-title library of the NES Classic. It offered an upgrade and fixed many of the cons of the NES Classic, but acknowledged that the emulation was a bit of a grey area, with the look not being quite as nice as the Classic.

The final cost was between $60 and $70, depending on the compents you choose.
