What is a game ROM

A game ROM is essentially the program that is run on a console game. The program itself can't be changed, whether it is on a DVD or a game cartridge. The term "game ROM" usually refers to the game cartridges used in classic consoles such as Atari and Nintendo NES. Some of the games have been converted for use in a PC by using an emulator, a computer program that makes the game program think its being run by the game console.
