CoilSnake is the most powerful mod making tool for the game EarthBound. CoilSnake deconstructs the game's assets into individual text and PNG files, and then lets you "build" a new ROM using modified assets. Most of the game's data is editable by CoilSnake, making it possible to create entirely new games in the EarthBound engine.
Download and usage instructions for Windows and Linux can be found on the CoilSnake website.
