What Is A ROM Hack?

To start, ROM stands for read-only memory, which comes from the chip inside video game cartridges that holds all the data pertaining to that specific game. This data can be copied via a ROM image or a ROM file, and this is what’s used for ROM hacks.

ROM hacking is the process of taking a game’s files and altering them to create a new experience using the old game’s engine. With the proper editing tools, a ROM hacker can change things ranging simply from dialogue options to core gameplay mechanics and level design.

ROM hacks will generally stay faithful to the original game design, opting instead to create new levels, introduce new music and game elements, and aim to create a totally new way to experience the original game.

How Does ROM Hacking Work?

Most ROM hacks are done through the use of a hex editor, which focuses on editing text as well foundational concepts in any particular game such as item properties and assembly hacking. Learn to use a hex editor is the bedrock for anyone looking to work on a ROM hack.

There are also additional editing systems depending on the task at hand, such as a tile editor to use for changing graphics and a level editor for redesigning levels already in the game. Which tools a hacker will use depends entirely on the scope and goal of the specific hack they are working on.

When the ROM hack is completed, it is almost always played via emulator, as this is the easiest way to transfer and upload the files. However, there are certain patched ROMs which are playable with the original cartridges and hardware, and finding ways to incorporate emulated experiences on the original consoles has become a more popular pursuit.
