OpenEmu is a free (you can donate if you like their software) and open source graphical front end for many software emulators (which in turn are also open source). Our favorite emulation software comes from OpenEmu and we'll show you how to get it up and running. You're going to need some emulation software to help you get started.
If you're thinking about your childhood games on Atari, ColecoVision, or that old Commodore 64, you can relive those memories with retro gaming on your Mac.
