People love stuffing Raspberry Pi's into all kinds of retro game consoles, but the PlayStation hasn't seen much love. Over on Pi Supply, they show you how to wire in a Pi to a PlayStation console.
In order to get this up and running, you'll need some soldering skills and a small handful of parts. You'll also be using a PlayStation 3 controller as opposed to an old wired PlayStation controller. The software itself is no different than other Pi-powered retro game consoles, but if you're a fan of Sony's contribution to consoles, this is a fun case to build.
