- This is an explanation of a what a console emulator does. For a list of existing emulators, see list of video game emulators.
A
video game console emulator is a type of
emulator that allows a computing device, usually a
personal computer, but also other
video game consoles and mobile devices running operating systems such as
Android to emulate a video game console's hardware and behavior and play games for that platform. Emulators are most often used to play older video games on personal computers and video game consoles, but they are also used to play games
translated into other languages or to modify (or
hack) existing games. More often than not, emulators offer additional features above and beyond that of the original console, such as
multi-controller compatibility (such as
PSX controllers being used with
N64 games and vice versa),
timescale control, higher framerates, higher resolutions, unlocking of gameplay features, memory modifications (like
GameShark), and one-click cheat codes. Emulators are also a useful tool in the development process of
homebrew demos and the creation of new games for older or discontinued consoles.
