An emulator is a program designed to mimic another device such as a gaming console. By using an emulator and a "ROM," which is an electronic backup of a game disc or cartridge, you play back-up games on your computer. These emulator programs zip into a ZIP archive to make them easier to download. You can unzip the program to access the Emulator by using native controls in Windows.
Instructions
1. Click "Start" in Windows and select the folder where your emulator ZIP file is, such as "My Downloads."
2. Right-click on the ZIP file, a list of options appears.
3. Select "Open." A box appears that has your emulator EXE file inside of it. Click and drag the file to your computer's desktop or other folder to unzip it. Double click the file to install it on your computer.
