Play Super Mario Odissey Demo Version Online

Game Overview

Okay, so the Super Mario Odyssey Demo Version on SNES is this weird little "what if" scenario—like someone took the Switch game and shoved it through a time warp back to the 90s. You’ve got Mario bouncing around in crisp 16-bit glory, but with hints of Odyssey’s mechanics, like Cappy’s possession trick translated into pixel form. It’s janky in that charming, fan-made way, but the controls feel surprisingly tight for something that probably never existed officially.

The first level throws you into a condensed version of the Cap Kingdom, all chunky sprites and chiptune remixes of familiar tunes. You’ll double-jump onto goombas, snag a few moons, and maybe even possess a frog just to see how badly the SNES would’ve handled it. It’s short, obviously—more of a proof-of-concept than a full game—but there’s something hilarious about watching Mario’s hat physics reduced to a few bouncing pixels. If you’ve ever wondered what Odyssey would’ve looked like on a CRT, this is your answer.

Honestly, it’s less a demo and more a love letter to retro modders who refuse to let the SNES die.
