In Super Mario Maker 2, players can build levels exactly how they want, mixing and matching enemies, power-ups, and other elements. Which power up would you use first?

That's okay, Nintendo didn't either!

We currently don't have plans to implement multiplayer modes - mostly because we don't have the expertise on the team to do it well. But if you are familiar with switch hacking and have experience implementing rollback netcode, please contact us via Wizulus's discord.

The Wizulus level viewer now supports Open Course World levels! You can either click the link to the viewer from the OCW website, or enter the level code directly into the level viewer.

Also cool: opencourse.world is a *complete* reimplementation of the Mario Maker 2 server. Covers almost all of the functionality of the original, all black box reverse engineered. The client can't even tell it's talking to a fake server.

Let's GOOOO Welcome to the new home of trolls, glitches, and other levels Nintendo doesn't allow on their server. Focused primarily on serving the Ryujinx emulator, users can import their courses and connect directly through Course World in their game.

Unlike previous attempts at solving this problem, Open Course World is entirely compatible with the game itself, and does not require savefile editing or external programs. Log into our website via Discord or Twitch, and download a personalized mod to get you started right away!
