This baserom resource is provided to makers to create Super Mario World levels for the weekly Romhack Races, but it has also been built with general purpose hacking in mind and remains very flexible for any sort of project.
While lot of the changes made and patches included are to accommodate Kaizo level design in particular, it is perfectly suited to any sort of hack as those quality-of-life features are widely applicable.
