‘Cemu’ Wii U emulator released

A few days ago I was talking about the first actual Wii U emulator project. It looks like the wait for a Wii U emulator won’t be as long as we thought, because a different one was just released. It’s called Cemu.


Cemu is presented by the GBAtemp user as “world’s first Wii U emulator capable of running and rendering commercial games!

Here are some facts about the emulator:

  • Can run encrypted Wii U images (WUD) and RPX/RPL files
  • Internal resolution is 1920×1080 (if supported by game)
  • For controller input see here.
  • Contains basically no optimizations. Expect slow framerates and long load times.
  • Windows x64 only (other platforms may be supported later)
  • Requires OpenGL 3.3
    • Tested on NVIDIA: Runs fine on most recent driver
    • Tested on Intel: Garbled output but runs if OpenGL version is supported
    • Untested on AMD

Good thing is that unlike exjam’s emulator project, this one is not limited to Windows 10.

First users’ feedback has already come in. A lot of people question emulator’s legitimacy. Some people report it runs badly and crashes a lot. On the bright side, it actually loads games. For more info, check the FAQ below the video.

In the video, you can see NES Remix running:

And also The Legend of Zelda: The Wind Waker HD:


Can the controller be configured?
Not yet, it’s locked to using the GamePad via keyboard. Proper controller support will come in a future release.

Can I run extracted games?
No, when launching a Wii U executable directly (.rpx) no external files are supported. If you want to run a game, it needs to be in raw dump format (WUD or ISO).

Is there supposed to be sound?
No, audio is not yet supported.

What’s next?
The current plan is to release new updates at least every two weeks. A more detailed roadmap is in the works.

  1. Neat, gotta find out how to dump Wii U titles.

  2. Sorry but I can’t believe it is true

    • Well considering how the Wii U hardware is so similar to the Wii and Gamecube, it’s probably not as incredibly hard to create this as it would have been to create an emu for a completely new architecture. With that said, I’m super impressed and excited that is done so soon!

  3. The real news is Loadline, but it isn’t getting much coverage.
