Video game console emulator

A video game console emulator is a type of emulator that allows a computing device to emulate a video game console's hardware and play its games on the emulating platform. More often than not, emulators carry additional features that surpass limitations of the original hardware, such as broader controller compatibility, timescale control (such as fast-forwarding and rewinding), easier access to memory modifications (like GameShark), and unlocking of gameplay features.
