ROM Hacking


What is ROM Hacking?


ROM Hacking is the process of modifying a video game ROM image to alter the game's graphics, dialogue, levels, gameplay, or other gameplay elements. This is usually done by technically-inclined video game fans to breathe new life into a cherished old game, as a creative outlet, or to make essentially new unofficial games using an old game as a foundation.


ROM hacking is generally accomplished through use of a hex editor (a program for editing non-textual data) and various specialized tools such as tile editors, and game-specific tools which are generally used for editing levels, items, and the like, although more advanced tools such as assemblers and debuggers are occasionally used. Once ready, they are usually distributed on the Internet for others to play on an emulator.
