Cemu is a closed-source, Windows-only Wii U emulator. Currently, the GamePad, Classic, and Pro controllers are emulated. It also requires a high-end PC to run games at full speed, although there are numerous bugs that can crash games due to unimplemented features. The latest version of Cemu is restricted at first to project donors before being released to the public.[1]

Downloads[edit]

System requirements[edit]

  • OS: Windows 7 (64-bit) or above
  • GPU: OpenGL 4.0 or above, Intel iGPUs are not recommended
  • RAM: 4 GB minimum, 6 GB or more recommended

How to get games[edit]

  • Download an NUS downloader such as WiiU USB Helper
  • Get the zip file with all the currently dumped .tiks from the mega link under TIK DATABASE on this page then open it in WiiU USB Helper (just drag the entire zip file to the WiiUSBHelper)
    • You may need to sign in to view the forum post. User: gfyjhiuhiuh Pass: zTqE1yf56NGemZR (Alternatively just use a bugmenot password)
    • Alternatively, just paste this URL into WiiU USB helper - https://wiiu.titlekeys.com/ - although it'll give you a lot of download titles as well, which may not work on cemu (the .tik zip contains only retail disc games) THIS CONTAINS DLC and the .tik database doesn't.
  • Select the game you want to download, click get it and then download games
  • This will download the files for the game you chose (the same as the .tik's title). May I suggest that you choose your own region where possible, so the download is quicker (from your regional servers)
  • Now we need to convert the game into loadiine format so that you can load it in Cemu
  • Simply right click your newly downloaded game, then click Unpack/Convert to Loadiine
  • Load the .rpx file from [Your gamelocation]/code/[yourgame].rpx with cemu

Shadercaches[edit]

Normally, when playing a game in Cemu, a shader cache will be generated as you play. This will cause a lot of stutter and slow the game down the first time you play that level/area/game. Luckily, Cemu allows you to transfer your shader cache, allowing you to download one from a friend (or just someone else on the internet). Reddit seems to be a good place to get these shadercaches. Simply go here and search for the game you want a cache for.

  • Note that it is very difficult to generate a 100% complete shadercache for large games and therefore this will not definitely completely eliminate stuttering.

Transferable shader caches may cause slowdowns in some games, on some graphics cards (observed in Geforce 970s). If this is the case, delete both your transferable and precompiled caches as well as the .bin and /toc file in your NVIDIA GLCache found in C:\Users\(You)\AppData\Roaming\NVIDIA\GLCache\(hexstring)\(hexstring). In this case, you will have to generate your own shaders.

  • This may get fixed after 1.7.0, who knows?
