Play Super Mario World Ultimate Mayhem 2 Online
Mario’s world gets twisted—Yoshi breathes fire, levels fold in on themselves, and Bowser’s kids pull new dirty tricks while remixed tunes mess with your nostalgia. You’ll die a lot figuring out secrets that actually make you think.

Super Mario World Ultimate Mayhem 2 is the kind of romhack that makes you question why Nintendo didn’t think of this stuff first. It starts familiar—same green hills, same happy little clouds—but then suddenly Yoshi’s spitting fireballs, levels twist into weird alternate paths, and Bowser’s kids have new tricks that’ll make you yell at your CRT. The music’s been remixed just enough to feel fresh but still hits that nostalgia sweet spot.
What really gets me are the secrets. They’re not just hidden blocks in obvious spots—you’ll actually have to experiment, like bouncing off enemies in weird ways or holding down some obscure button combo mid-jump. And the difficulty? Let’s just say I died more in the first world here than in the entire original game. But it never feels cheap, just... delightfully unhinged.
If you’ve ever thought "I wish Super Mario World had more chaos," this is basically that thought turned into a cartridge. Just maybe don’t throw your controller.
