An emulator is a piece of hardware or software that allows one computer system to mimic the behavior of another. Typically, an emulator enables the host system to run applications or make use of peripherals made for the guest system. Even though the general aim of emulation is to replicate the experience of using the original hardware, many game emulators also come with extra features like the ability to take screenshots and save game states. It is also possible to play games created by fans thanks to emulators.
