Super Mario 64 co-op is available through sm64coopdx, a community project for the Super Mario 64 PC port. Its official materials describe online multiplayer in a shared game world, with the project website claiming support for up to 16 players. They do not confirm couch co-op or split-screen, so playing together on one screen should not be assumed.

What is sm64coopdx?

sm64coopdx is an online multiplayer project for the Super Mario 64 PC port and the official continuation of sm64ex-coop, according to the project’s GitHub repository. The repository describes synchronizing game entities and levels so multiple players can interact in the same world. That is a shared-world multiplayer experience, not simply several character models appearing on screen.

How many players can join?

The official sm64coopdx website says the project supports up to 16 players. This is the project’s stated maximum, not an independently verified performance result; the available official materials do not detail how session configuration or individual setups affect play.

How do you get started?

The official site provides a brief starting instruction rather than a complete installation walkthrough:

  1. Download the latest release from the sm64coopdx GitHub releases page.
  2. Drag and drop a .z64 ROM file as directed by the project website.

Those instructions do not explain how to obtain a ROM, provide legal advice, or specify all setup steps. The consulted official materials also do not establish current operating-system support, controller configuration, or whether a particular launcher works with the latest release.

Can you play couch co-op or split-screen?

The available official sources describe online multiplayer, but do not confirm same-device couch co-op or split-screen. A Reddit discussion asks, “Is this viable with couch coop?” That is a question from a user, not evidence that local play is supported. If your goal is two people playing on one computer and screen, check current project documentation for an explicit answer before setting it up.

What does a co-op clip establish?

A clip or discussion can show the project being used, but it does not by itself establish every setup detail or prove local multiplayer support. One Reddit poster says they used Super Mario 64 [Co-op DX] through the Quiver Launcher; that single user report is not an official recommendation or confirmation of current compatibility.
