Wii U emulator Cemu 2.0 out, goes open source and gets Linux support

By - | Views: 47,153

It has finally happened. Cemu, the Wii U emulator has a big new 2.0 release and it is now officially open source and available for Linux too.

For Linux, most people do need to compile it from source as there's only an Ubuntu package right now but the developer has said in the announcement post that they're looking into AppImage and Flatpak to make it easier. While Cemu should work fine on Linux, they also mentioned there are some lingering issues mostly around the user interface. Part of the reason it was open sourced, was that the main developer had been doing it alone for quite a while and so now it's open source hopefully more people will help develop it further.

Main changes for Cemu 2.0 include:


  • Cemu is now open-source!
  • Preliminary Linux builds are available, but be warned that they are still very rough around the edges
  • Going forward, we simplified the versioning a bit by using shorter version numbers (2.0, 2.1, 2.2, 2.3..)
  • Updated all dependencies. Most notably SDL (input & motion) and wxWidgets (UI).

Other changes:

  • Fixed a crash in the H264 video decoder. Resolves crash on Smash title screen
  • Made nsysnet a little less crash prone. Fixes crash in Call of Duty: Black Ops II
  • Fixed a logging related crash that could occur under very specific circumstances. Seen in Wind Waker if letting the game idle on the title screen for 2 minutes.
  • Fixed a crash that could happen when the path to Cemu.exe contained unicode characters
  • Fixed a crash that could happen when loading .elf homebrew
  • The account list in the title manager save exporter is no longer empty
  • Latency for wiimotes should be a bit better now
  • Added symbol/function list to debugger + other small debugger/assembler improvements
  • Implemented API: coreinit.FSOpenFileExAsync (used by some homebrew)
  • Many more under-the-hood changes and fixes
  • Some more work towards a Stop&Restart emulation feature. Not ready yet but we are getting there

See it on GitHub and the official site.

Probably not worth doing until proper builds are posted (as in, not preliminary).

I'm a bit surprised that a relatively new project is using wxWidgets; I think VLC used to use that.

Omg I want this on the Steam Deck with a native Linux build and for that to be the tablet controller with my Windows 11 desktop pc as the TV and USB sensor bar to totally mimic what's possible with a real Wii U!

No laughing here - we've all got to start somewhere!

Could you go into more detail about what file you've downloaded, what Linux distro you're using, and so on, please? That will provide more of an idea about what needs to be done next.

Alternatively, you may want to consider asking this on the forum instead, since that's a more appropriate spot for bigger questions, and it'll hopefully catch the eye of more people who might be able to help. There's a specific section for retro-gaming and emulation, even!
