Rad project tutorial from Gus up on PIMyLifeUP.
In this tutorial I go the through the steps of setting up Raspberry Pi DOSBox. This is a pretty easy process that will let you play the hundreds of great old DOS games that have been released as shareware, demos and of course freeware.
Now DOSbox will only let you play games designed for the MS-DOS operating system. If you want more than just this, then be sure to check out my tutorial on setting up retro pie for the Raspberry Pi.
