Probably not quite as cool as the ALttP randomizer, but still pretty rad if you think SMW is getting stale after sixteen years. Simply visit the website, upload a copy of the ROM, set the parameters, and download your unique, randomized SMW game. The Randomizer is still in development, but still has a lot of cool features. It doesn't build levels from scratch, but rather mixes up the levels already in the game. You can also randomize sub-levels and exits. Enemies, powerups, and other level properties can also be mixed up, producing a Super Mario World that is full of chaotic bullsh*t FUN! If you mess around with this, be sure to post some results here. Maybe we can organize a race sometime.
