The latest version of CEMU, 1.17.1, is certainly a technical marvel. With the right configuration and the right precautions, in fact, it allows you to play practically all Nintendo Wii U games on your PC in a completely identical way, if not openly better than the original version. Below you will find our CEMU installation guide.
Whether or not you are in favor of emulation, CEMU (which is perfectly legal as long as you don't download pirated games) has great merit as it allows the important stock of titles of the prematurely disappearance Wii U not be forgotten. The emulator in question, however, reached the headlines above all for the important work of emulation and optimization carried out with The Legend of Zelda: Breath of the Wild. In this guide we will explain how to correctly install the latest version, 1.17.1, so that you can play your favorite Wii U titles.
Soultricks.com assumes no responsibility in case of non-compliant use of this guide. The use of emulators is fully legitimate only if the user owns the emulated game.
But stop the chatter and let's move on to the configuration guide, remembering first of all that in order to play The Legend of Zelda: Breath of the Wild you must first buy the original Nintendo Wii U copy. Only in this way you will not violate the law and help the developers to continue their work of updating.

1) Update all your video card drivers.
First, make sure you have installed the latest drivers available for your video card by clicking on the links below:
2) Download the necessary files
Below is the list of downloads to be made in advance:
- C ++ Redistributable 2017: Download
- CEMU Download: CEMU 1.17.1
- CEMUHOOK: Download
- Shader Cache (1.4.1 / 1.5.0 update Cache): the old link is no longer available, but you can easily search for your shader cache with a Google search: CEMU Cache. Or check out this subreddit
- USB Helper Launcher: Download
- Wii U USB Helper: version 0.6.1.616 (recommended)
NB: Wii U USB Helper is no longer functional, so you must download the version we inserted above and then follow the steps in paragraph 7 to be able to use it.
Download and unpack all files saved on the desktop, except USB helper and Wii U USB helper for which we will create special folders (see point 7 of this guide).
2.1) Open the folder where you unpacked CEMU and copy the contents of the unpacked CEMUHOOK folder into it.
2.2) Right-click on the CEMU executable file and select the “Compatibility” menu in the screen that appears. At this point, choose to always open CEMU with administrator benefits and select, at the bottom, the option “Execute DPI scaling override…” and on “Disable Full Screen Optimizations”. Click Apply, then Ok and close the screen.
2.3) NB: unlike previous versions of CEMU, Graphics Packs are now downloaded automatically once you click on the application executable, so it is no longer necessary to download them separately.
3) Pad configuration
3.1) Start CEMU and from the Options menu, Input Settings, create a new profile.
3.2) Select the options as shown in the image below. If you are using an Xbox360, DualShock 3, or DualShock 4 controller, remember to use a program such as Inputmapper or DS4windows. Click Save.
4) Configuration of the CEMU Options
4.1) From CEMU select the Options drop-down menu and then in Graphic Packs enable all the options as shown in the photo below:
Tip:: If you still have noticeable fluctuations in the frame rate after enabling the options below, try disabling GX2DrawDone and to install the latest version of FPS ++.
Tip 2: Of course, if you don't have a 4k monitor, select the right resolution for your PC / TV.
5) Other options to configure
Navigate through the CEMU menus and activate or disable these functions:
Low GPU Buffer Cache Accuracy;
Full Sync on GX2DrawDone (read disclaimer above)
Custom Timer: CEMU Default 1x, / QPC
In the DEBUG Menu: Default MM Time Accuracy 1ms
6) Set the multithread
The new CEMU now makes it possible to use the computing power of the new processors for graphics processing. If you have a multithreaded processor, such as Ryzen or the new i5 / i7 with 4/6 or 8 cores, from the "CPU " click on "dual core" or "triple core".
Tip:: The latter setting should only be used with machines with at least 6 cores. If you have a quad core, use the dual core option.
7) Download games with Wii U Helper USB
As reported in the paragraph where we list all the files to be downloaded in advance, Wii U Helper USB is no longer functional but a user on Reddit managed to create a launcher capable of "bringing it back to life".
7.1) Preliminarily create three folders in the position where you want to keep your titles:
"Helper" (for program files)
"Helper DL" (for download files)
"Helper EX" (for extracted files)
7.2) After downloading Wii U Helper USB and USB Helper Launcher as indicated at the beginning of the guide, please follow the steps below:
- Extract Wii U Helper USB, then extract the launcher in the same folder (“helper” if you have chosen to call it after us);
- Download MakeHostsJson.exe, copy it into the folder where you have decided to install USB helper, launch it and follow the instructions;
- Run USBHelperLauncher.exe and follow the on-screen instructions, a hosts file will be created. Create a desktop icon and you can use Wii U Helper USB without any problems. If prompted by a warning message, select “override”.
7.3) Once you have selected your Wii U region, you will be asked where to find them Wii U Title Keys. For obvious reasons, we will not give you any indication to this effect, reminding you that the operation is legal only by purchasing the original version of the game.
7.4) Once you have selected your game, select the HELPER DL download folder and the HELPER EX extraction folder by clicking on the appropriate buttons at the bottom "Set Download Directory" and "Set Extraction directory"
7.5) After completing this step, you can click on the flashing “Start Download” icon. You will be asked to install the DLCs and updates as well, click yes.
7.6) Before the operation is completed, click on "Download manager" (on the right side of the program there is a slightly hidden tab that indicates the download status) and then select the UNPACK option to directly unpack the files. If the option is not present, once the download of the title is complete, right click and select Unpack.
7.7) Start CEMU and select the Helper EX folder as the source from which to draw the titles.
8) Install the DLCs and updates before starting the game
8.1) Start CEMU and click on “file” then on install update / dlc.
8.2) Navigate in the HELPER EX folder, then in the update files folder and in the meta subdirectory and finally select the Meta.XML file.
8.3) Repeat the previous step for the DLC as well, obviously starting from the folder where you unpacked the DLC.
9) Starting the game
9.1) Start CEMU, select File and then “Load” and navigate to the HELPER EX folder.
9.2) Select the game folder (not the update folder, nor the DLC folder) and then the CODE subdirectory. Finally, open the file with extension ".Rpx."
9.3) Wait for the shaders to load. The first start may take a few minutes.
The game is done!
