yuzu starts with the error “VCRUNTIME140_1.dll was not found”
Current versions of yuzu require the latest versions of Microsoft Visual C++. Please download and install the following dependency:
https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
Go to Visual Studio 2015, 2017 and 2019, and select the link next to x64.
How do I get Games?
You are legally required to dump your games from your Nintendo Switch. To do so, please follow our in-depth Quickstart Guide.
yuzu starts with the error "Missing Derivation Components"
yuzu requires console keys to play your games. Please follow our Quickstart Guide to dump these keys and system files from your Nintendo Switch.
These console keys (prod.keys/title.keys) need to be placed in the following directories:
You may need to create the following "keys" folder:
- Windows:
C:\Users\USERNAME\AppData\Roaming\yuzu\keys - Linux:
/home/USERNAME/.local/share/yuzu/keys
NOTE: This yuzu directory can be quickly accessed by selecting file/open yuzu folder within the emulator
yuzu starts with the error "Unable to start application: Os { code: 2, kind: NotFound, message: “The system cannot find the file specified.” }"
This problem is usually caused by a false positive of your antivirus software, most commonly by Avast and AVG. These applications will often incorrectly detect yuzu as malicious software and delete the executable as a result.
You can confirm it is a false positive with an online scanner, such as VirusTotal if you wish.
To fix this, you'll need to either disable or uninstall your antivirus software. Make sure to reboot if you choose to uninstall it.
Afterwards, follow the instructions below for yuzu will not update further or starts with a Qt platform error to delete any residual files of the failed installation.
yuzu will not update further or starts with a Qt platform error
- Close all instances of yuzu and any installer processes you may have running.
- Press Win+R, in the opened window type
%localappdata%and press Enter. - Select the
yuzufolder and delete it. If it is being used by another process, please double-check that you do not have any yuzu related applications running. - Launch the installer and install yuzu again.
yuzu closes when opening Configure
This problem may be caused by a corrupt configuration file.
Press Win+R, type %appdata%\yuzu\config and delete the qt-config.ini file. Your global settings will be lost after doing this, reconfigure accordingly.
Alternatively, some screen recording applications use dubious methods to inject themselves into software, causing crashes. Some examples are Bandicam, Action and Screenrec. Uninstall the software if you have it installed.
We recommend using OBS Studio, Radeon ReLive, Nvidia ShadowPlay or Microsoft XBox Game Bar.
My game is Lagging and Dropping to Low Framerates
You are likely experiencing Shader Caching. Shaders are small programs running on a graphic card, responsible for rendering graphics like terrain, explosions, characters, etc. Since a PC cannot directly execute switch shaders, It first has to translate them to a format a PC can understand. This translation process is time-consuming and you'll notice it in two ways:
-
While playing, if yuzu needs to translate a new shader, the game will stutter. Loading into a game for the first time can give long freezes due to the number of shaders. As you keep playing, the amount of stuttering will decrease.
-
When launching a game, the shader cache is loaded. To speed up this process there exists an additional "precompiled" cache. This cache may get reset every time you update yuzu or install a new GPU driver. The precompiled cache will then be compiled from scratch, causing a longer load time.
Currently, the Vulkan renderer does not have a disk shader cache. This means that subsequent game loads will require the building of shaders each time.
IMPORTANT: Since the cache stores parts of the game, we don't condone sharing or downloading these, since it is considered piracy
How do I use mods or cheats?
For a list of useful mods for your favorite games, check our database with Switch Mods
To add mods to a specific game, simply right click the game in yuzu's games list, select Open Mod Data Location and structure your mod files similar to this example:
Mod directory/mod name/romfs
or
Mod directory/mod name/exefs
To add cheats, structure your cheat file similar to this example:
Mod directory/cheat name/cheats
An example of a correctly structured mod directory can be seen below:
The mods provided on our Switch Mods page are already structured accordingly and only need to be extracted into the mod directory folder as is.
Once added to the correct mod directory, simply right click the game again, select properties and activate the installed mod. The same process can be followed in reverse for de-activating mods
How do I install game updates or DLC?
Installing updates and DLC is simple. In the top left corner of the emulator window, select File / Install Files to NAND, then select the file you wish to install. Once installed, your files should load automatically and the installed update or DLC will be shown in the games list add-ons column of the corresponding game.
If you wish to activate/deactivate a specific update or DLC then right click your game in the games list, select Properties, then enable or disable as needed.(See Below)
Reinstalling or Overwriting Updates/DLC is as simple as following the above instructions, selecting your files and installing your Update/DLC. When doing this, any previously installed files will be removed and replaced by the newly installed versions.
How do I uninstall game updates or DLC?
To delete your installed game Updates or DLCs, right click your game, then select Remove. From here you can delete/uninstall your game Updates and DLCs from the options list (See Below)
How do I set up my controls?
Since the Nintendo Switch is a complicated device controller input wise, you will need to change some input settings depending on the game you wish to play.
Open the yuzu settings and go to Controls.
For all games other than Pokemon Let's Go set the controls like this:
- Click on the checkbox next to
Connect Controllerif it is not already checked. - Select
Pro Controllerin the combobox below if needed (this is also the default). - Select your desired input device under
Input Device. - Controllers: All buttons should automatically be mapped for the selected input device.
- Keyboard: The
Defaultsbutton on bottom right sets default keyboard mappings. - Change mappings if desired.
- Repeat steps for other players if desired.
- Confirm with
OK.

How do I use my GameCube controller adapter?
The GameCube adapter communicates with yuzu over the libusb protocol. This works natively on Linux, but requires the installation of a compatible driver on Windows using Zadig.
Zadig driver installation
Plug in the GameCube controller adapter if it hasn't been already. Download and launch Zadig.
If you're using the Mayflash adapter, make sure you switch it to Wii U or Zadig won't pick it up properly.
-
From the
Optionsmenu in Zadig, selectList All Devices -
In the pulldown menu, select
WUP-028. Ensure that its USB ID is057E 0337.
- If it does not appear in the list then try inserting the adapter (specifically its black USB cord) into another USB port.
- On the right column, select
WinUSBthen clickReplace Driver. SelectYesto modify the system driver.
When the notification that the driver is installed successfully is displayed, you can close Zadig and continue to configuring the controller with yuzu.
GameCube controller configuration
Ensure the adapter is plugged in prior to launching yuzu. Then follow the How do I set up my controls? instructions, selecting Gamecube controller X as the Input Device, where X is the port in which the controller is plugged into.
How do I add a save to my Game
To add a save, simply right-click your game in the Games List, Select Open Save Data Location, then Select your User from the Profile Selector
Once your Save Data Location is open, place your game saves in this directory
yuzu closes when I try to open it
Disconnect any USB gamepad you have and relaunch yuzu.
Games fail to launch with the error: "WerFault.exe - Application Error - The application was unable to start correctly"
This typically occurs when yuzu runs out of RAM. Increase the size of your pagefile to resolve the issue.
