Question : What do you do when you have a Raspberry Pi kicking about, free time and a geeky fascination with Manic Miner, Lemmings & Mario Cart.
Answer : You download a copy of RetroPi on to your SD card and voila.
RetroPie allows you to turn your Raspberry Pi or PC into a retro-gaming machine. It builds upon Raspbian, EmulationStation, RetroArch and many other projects to enable you to play your favourite Arcade, home-console, and classic PC games with the minimum set-up. For power users it also provides a large variety of configuration tools to customise the system as you want.
RetroPie sits on top of a full OS, you can install it on an existing Raspbian, or start with the RetroPie image and add additional software later. It’s up to you.
