Cemu Guide

FAQ

If you need further help, ask on the official Cemu Discord Server for assistance.

Does Cemu support 32-bit systems?

No, Cemu will never support 32-bit systems. 32-bit applications can only use up to 4GB of RAM, which Cemu frequently exceeds.

Does Cemu support macOS or Linux?

Yes, experimental native builds are now available for both macOS and Linux.

For Linux users, we suggest using WineOpen in new window and LutrisOpen in new window to run Cemu. Experimental native builds and AppImage builds are also availableOpen in new window if you would like to use them.

If you have an Intel Mac, we suggest running BootcampOpen in new window to install Windows, and to run Cemu there instead. The macOS build uses a translation layer that can cause low compatibility, crashes, graphical issues and slow performance.

If you have an Apple Silicon Mac, or don't want to install Windows on your Intel Mac, I have written an installation guide for the native macOS builds on my personal site at cemu.emiyl.com/installationOpen in new window.

How do I play games if I do not have a Wii U?

You can not. We do not support piracy here and obtaining games without dumping them from your own console is illegal.

Can I play online without dumping files from my Wii U?

No, you must dump files from your Wii U to play online.

Think of them as a "username and password" to Nintendo servers. Nintendo gives each Wii U an authentication to access their servers, and without it, Nintendo will not allow you to connect to them.

What is the mlc01 folder?

The mlc01 path stores the emulated Wii U internal memory, including:

  • System files and apps
  • Installed games, updates and DLC's
  • User-created save data

This should be on a storage drive that Cemu will always have access to, with lots of free space. By default, the mlc01 path will be stored in the Cemu directory.

If you delete this folder everything will be gone. If this path ever gets reset, make sure to set it again in Options -> General settings -> MLC Path.

What are community graphic packs?

Community graphic packs allow you to visually alter a game and how it will run, including:

  • Displaying at higher resolutions
  • Running at higher framerates
  • Adjusting colours and bloom
  • Improving anti-aliasing
  • Applying game modifications

We recommend that you download these to allow tweaking your games for better performance.
