Retro gaming has always been a favorite thing for me to do on my spare time. There is nothing like breaking out the old Nintendo Entertainment System and playing a few classic levels of Super Mario Bros. Yes, you could always blow the dust off that old NES or SNES system, and spend a bit of time trying to get the game to work or you could use an emulator. Emulators have been around for quite a while, and exist on almost every platform. Perhaps one of the most popular NES emulators FCEUX, has been around since 2008, and is one of the most solid NES emulators out there.
