Do you like to play classic arcade games? If you do then you may need emulator. What is emulator? It allows your computer to act like a console system such as the Apple IIe or the Atari 2600, which are used to emulate the hardware of a variety of classic arcade games. Not all classic arcade games emulated, but those games made before 1992 are. If it is your first time for emulators, you must download an emulator and unzip it. If you are not familiar with the procedures, you must read the documentation carefully.
There are two types of emulators. The first one is the single-system or the single-game emulator. For example, NES emulator, Apple II emulator, etc. The second one is the multi-emulators, for example MAME. It can emulate hundreds of arcade games, although not all arcade games can run on the same kind of system. Emulator is the solution for not spending a lot of time reprogramming or porting the classic arcade games to a new console.
