Emulation truly is great and super convenient! I do love collecting retro games and being able to hold the physical media in my hands though, so recently I've been dumping the ROMs and images from my personal collection so I can play them through emulators.

The best part, especially with something like RetroArch, is that you can keep track of a large set of games across a variety of systems easily. Oh, and the Retro Achievements feature is pretty awesome too!
