When your emulator starts throwing persistent graphical glitches, crashing on boot, or failing to load titles after an update, a full configuration and cache reset is often the only fix. Resetting Yuzu doesn't have to mean losing your progress, provided you know which directories to target and which ones to leave alone.
You can perform a clean reset by locating your application data folders, clearing corrupted shader caches, or wiping the configuration files back to factory defaults. Whether you're troubleshooting a broken installation or preparing a fresh slate for new firmware, you can wipe and revive your setup safely.
Locating Your Yuzu Data Directories
Before you delete anything, you need to know where Yuzu stores its vital files. Unlike traditional PC programs that keep everything in a single program files directory, Yuzu splits its configuration, save files, and caches across specific user directories.
To open your main storage folder instantly, launch Yuzu, click on File in the top-left corner, and select Open Yuzu Folder. This opens your roaming profile directory in your operating system's file explorer. Inside, you'll see several key subdirectories:
- config: Houses your global settings, controller mappings, and UI preferences in plain text configuration files.
- cache: Stores pipeline caches, custom graphics settings, and temporary build data.
- nand: Contains your virtual Switch internal memory, including installed system archives, title updates, DLC, and save data.
- dump: Holds game updates or decrypted romfs/exefs dumps if you've extracted them for modding.
Knowing these paths prevents you from accidentally nuking your save files when you only intended to clear a broken graphics cache.
Step-by-Step: How to Wipe Configuration and Caches
If your goal is to fix weird behavior or stuttering without losing game progress, you should clear your settings and shaders first. Corrupted pipeline caches are the primary culprit behind sudden boot crashes.
- Close Yuzu entirely and verify no background processes are lingering in your system task manager.
- Open your Yuzu folder via the shortcut or by navigating to your user application data directory.
- Delete or rename the config folder to reset all emulator settings back to default.
- Open the cache folder and delete the contents inside to clear out old pipeline shaders that might conflict with new GPU drivers.
- Launch Yuzu again. It will generate fresh configuration and cache directories automatically, giving you a clean software environment.
This method leaves your virtual NAND and save states completely intact while purging the corrupted junk files causing your performance drops.
How to Protect and Back Up Your Save Data
If you need to perform a complete nuclear wipe—such as when moving to a new drive or dealing with deep NAND corruption—you must isolate your user save files first. Losing dozens of hours of in-game progress is avoidable with a quick manual backup.
Right-click any game in your Yuzu main menu and select Open Save Data Folder. This drops you directly into the specific user profile directory within the NAND structure.
To back up everything securely:
- Navigate upward in the directory tree until you find the main save folder.
- Copy the entire contents of the save directory to an external backup folder on your desktop or secondary drive.
- If you want to wipe everything clean, you can now safely delete the nand folder entirely.
- After resetting or reinstalling, paste your backed-up save folders back into the newly generated NAND path to restore your progress.
Troubleshooting Stubborn Emulator Crashes
Sometimes a simple cache clear isn't enough, especially if a bad title update or corrupt DLC was installed directly to the virtual NAND.
If a specific game refuses to boot past the initial loading screen, right-click the title in your game list, hover over Remove, and select Remove Installed Updates or Remove Transferable Shader Cache. This targets the specific title without requiring a full system wipe.

Frequently Asked Questions
Will resetting Yuzu delete my game saves?
Not unless you explicitly delete the nand folder or your profile's save directory. Clearing configuration files and shader caches leaves your save data untouched.
Why do games stutter heavily after a reset?
When you clear your shader caches, Yuzu has to rebuild them from scratch as you play. Stuttering will naturally decrease over the first few minutes as new shaders compile during gameplay.
How do I restore my controller layouts after wiping the config?
Your controller profiles are stored in the config folder. If you backed up your old config folder before wiping, you can copy the specific input configuration files back over to avoid remapping your hardware from scratch.
