In computing, an emulator is hardware or software or both that duplicates (or emulates) the functions of a first computer system (the guest) in a different second computer system (the host), so that the emulated behavior closely resembles the behavior of the real system.
Blah, blah, blah. It basically means you can play games from things such as the classic NES, to Xbox 360, and everything in between on your computer.:thumbsup:
Step 1: First you have to find an emulator you want. You will have to google it to find a game console specific emulator.
Step 2: Download, Save, and now you can start the emulator.
Step 3: The next thing you need to know about is ROMs. ROMs are basically the games you use on your emulator. A popular website for downloading ROMs can be found here.
Step 4: Download whatever ROM you want to play on your emulator. Once it is saved, extract the files to your emulator using WinRAR. (Download to WR is found above.)
