Q1. 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:
Go to Visual Studio 2015, 2017 and 2019, and select the link next to x64.
Q2. 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.
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
Q3. 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.
Q4. 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 yuzu folder 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.
Q5. 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
Q6. How do I use mods?
For a list of useful mods for your favorite games, check official (yuzu) 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
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
Q7. 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.
Q8. How do I uninstall game updates or DLC?
Due to current file system limitations, there is no easy way to uninstall a specific update/DLC.
It is usually easiest to just delete everything and then reinstall any updates and DLC that you need.
Installed updates/DLC are found in %appdata%\yuzu\nand\user\Contents\registered\.
To remove them, you will need to delete this registered folder.
Remember to reinstall any updates or DLC you need.
Afterwards, go to Settings / System / Filesystem tab and click on Reset Metadata Cache on the bottom. This will refresh the games list addons column.
Q9. 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.
In the input window dropdown, Select Custom, then click on Configure.
For all games other than Pokemon Let’s Go set the controls like this:
- Map your controls by clicking on Configure next to Pro Controller.
- Make sure to map your analog sticks by clicking on the Set analog Stick button if you are using a controller.
- Restart yuzu after you are done for the new settings to take effect.
For Pokemon Let’s Go set your controls like this:
- Map your controls by clicking on Configure next to the Joycons Docked checkbox.
- Make sure Player 1 is set to None as depicted in the screenshot.
- Make sure to map your analog sticks by clicking on the Set analog Stick button if you are using a controller.
- Restart yuzu after you are done for the new settings to take effect
Q10. 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
