Cemu, the world’s first Wii U emulator, is now available


A Wii U emulator for the PC, known as Cemu, has suddenly surfaced on the gbatemp forums. It is said to be fully functional in terms of running and rendering commercial games. However, at this point in time, it’s pretty unoptimized and will need a number of updates before it can perform well on a wider range of PC hardware. At present, you should expect low frame rates and long load times.


Currently, the emulator lacks controller support, and you have to make do with a PC keyboard. You’ll be able to configure the Wii U Gamepad functions to your keyboard via the emulator’s key mapping menu. Also, audio support is unavailable at present. Given that this is a very early build, these features are likely to come soon in future updates.

Cemu requires OpenGL 3.3, and can run encrypted Wii U images (WUD) and RPX/RPL files. It supports an internal resolution of 1920×1080, provided that the game you’re running also supports it natively. Also, keep in mind that the emulator only supports 64-bit Windows operating systems.

According to the release notes, the emulator has been tested on Intel and Nvidia hardware. AMD hardware, both CPU and GPU, have yet to be tested with Cemu.

You can download the emulator from the link provided here. For controller inputs, follow the link here.

    Controller inputs link doesn’t work. And according to CEMU’s homepage, AMD hardware has been tested and does work, Intel doesn’t if it does not support open gl 3.3

  • wii u emulator? my computer couldn’t even run dolphin gamecube emulator that’s how crappy my computer really is, until I get everything upgrade to 8 cores and good luck downloading every 25 to 50 gb-like file because wii u games hold that much like a blu ray disc on a slow connection.

      Not true, It only has a DVD drive. The biggest rom I’ve seen is 4.04Gb and that is super mario 3D world.

    Okay, still buying a Wii U on the 27th of October, that emulator is not changing that. I’d rather play it with the proper controller, the Wii U gamepad, aside from it’s low battery life, is so great, most comfortable controller of all time (even beating out the gamecube controller.)

      you can use the normal gamepad.remember this is version 1.0.0 and mapping the gamepad is already a function.give this thing like a month and it will be so much different

        Good point, it might improve- but I’ll still have the proper experience anyway.

    They couldn’t make emulators of consoles ppl want but can’t afford?

    • Donovan Tull

      I think an Xbox One or PS4 is an emulator of PC……
      They’re almost entirely the same, except that they’re worse than PC’s. So what console are you thinking of instead? Which one do people want but can’t afford (I can’t afford it yet, I will soon though)?

      • Shining Jade

        how about a PS Vita … now that I want to see emulated…

        • Donovan Tull

          So….. an emulator of a poor emulator of a PC?

          I’ll pass. PS4 as it is is poor, not likely to have any decent games for another few years. Why would I want a lower quality version?

  • Mario Wii U

    May as well just go grab a Wii U!!
    Play the games properly.
