If you have a Raspberry Pi, the sky's the limit when it comes to things you can do with it. If you want to use it to get your game on, this project turns your Pi into an old-school gaming powerhouse using RetroPie and DOSBox.
It turns out that running retro games on your Raspberry Pi isn't that difficult. The blog Coding Epiphany recently ran a two-part series on getting your Raspberry Pi configured, set up and ready to game. First, they use RetroPie, a simple series of scripts to install RetroArch, a front-end packed with tools for multi-platform game emulation. Then, just to take it to the next level, they install DOSBox and set that up so you can run old x86 DOS games as well.
The instructions for each are at the links below, along with the commands you'll need to run and performance tweaks to make it all work smoothly. The best thing about this setup is it completely eliminates the need for multiple emulators and multiple software packages, so you can power up your Pi and play your favourite retro titles almost instantaneously.
