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?

While Cemu have stated in the past that a Linux build is planned in the distant future, currently no builds are available for MacOS or Linux.

Many users have managed to get Cemu working in Wine, however for best performance, we recommend running the emulator on Windows only.

How do I play games if I don’t have a Wii U?

You don’t. We do not support piracy here and obtaining games without dumping from your own content 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 won’t allow you to connect to them.
