People have been hacking Super Mario World for years. When I first played it, it was all about the secret pipes and magic whistles. I hate to admit, but that was a long time ago. There is a lot more to the game now than just tanuki suits and turning into stone. Now, there are entire online communities dedicated to hacking the game, building your own levels, and playing other people's custom built levels. Ones of these levels is so insane, that user PangeaPanga spent three years trying to beat it!
