### **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](https://yuzu-emu.org/help/quickstart/)._ ### **yuzu starts with the error "Missing Derivation Components"** ![](https://cdn.discordapp.com/attachments/512678820092968971/699337208443699307/Keys_missing.PNG) _yuzu requires console keys to play your games. Please follow our [Quickstart Guide](https://yuzu-emu.org/help/quickstart/) 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_ * Windows: C:\Users\USERNAME\AppData\Roaming\yuzu\keys **<- You need to make this "keys" folder** * Linux: /home/USER/.local/share/yuzu/keys **<- You need to make this "keys" folder** **NOTE: This yuzu directory can be quickly accessed by selecting file/open yuzu folder within the emulator** ### **yuzu starts with the error “VCRUNTIME140_1.dll was not found”** ![](https://cdn.discordapp.com/attachments/512678820092968971/699336946698158120/VC_missing.png) _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._ ### **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](https://www.virustotal.com) 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 `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._ ### **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?** _For a list of useful mods for your favorite games, check our database with [Switch Mods](https://yuzu-emu.org/wiki/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_ ![](https://cdn.discordapp.com/attachments/512678820092968971/697113928852963378/Mod_Format.PNG) _The mods provided on our [Switch Mods](https://yuzu-emu.org/wiki/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_ ![](https://cdn.discordapp.com/attachments/512678820092968971/697124627520159804/Mods_on.PNG) ### **How do I install game updates or DLC?** _Installing updates and DLC is simple.
