(skip through to get an idea of what it does)
It's the Super Mario World ROM editor. Quite easy to use if you're just making your own level (drag and drop, and then adjust size just like Mario Maker) and will obviously be much more powerful than Nintendo's version (custom graphics, custom bosses, custom overworld etc).
