Yuzu allows you to play Nintendo Switch games on your PC, but you need to properly import and configure them first. This guide will walk you through the process to ensure smooth gameplay.
1. Prepare Your Nintendo Switch Games
To play Switch games on Yuzu, you need game files in XCI or NSP format. You can legally dump these from your own Switch using nxDumpTool.
What IS an XCI on NSP File?
XCI (NX Card Image) is a file format used to store Nintendo Switch game data. It is a direct dump of a physical game cartridge, preserving the original structure and encryption.
Key Features of XCI Files:
- Cartridge Dump – XCI files are exact copies of Switch game cartridges.
- Includes Encryption – Retains Nintendo’s encryption, requiring prod.keys for decryption.
- Larger File Size – Can be bigger than NSP files due to additional data.
- Compatible with Yuzu – Yuzu can run XCI files once decrypted.
What is NSP?
NSP (Nintendo Submission Package) is a file format used for Nintendo Switch games, similar to how apps are packaged for installation. It represents digital game downloads from the Nintendo eShop or backups of installed titles.
Key Features of NSP Files:
- Digital Format – NSP files come from eShop downloads or game installations.
- Smaller File Size – Typically smaller than XCI files since they lack cartridge data.
- Requires Decryption – Needs prod.keys and title.keys to run on Yuzu.
- Compatible with Yuzu – Yuzu can load NSP files once properly decrypted.
XCI vs. NSP
| Feature | XCI | NSP |
|---|---|---|
| Source | Cartridge Dump | eShop/Game Install |
| Encryption | Encrypted | Requires Decryption |
| File Size | Larger | Smaller |
| Yuzu Compatibility | Yes | Yes |
Both formats work in Yuzu, but XCI is better for preserving cartridge-based games.
2. Install Yuzu and Set Up Keys
Before running Nintendo Switch games on Yuzu, you must install the emulator and set up the necessary decryption keys. Yuzu requires prod.keys and title.keys to read encrypted game files. Without these keys, games won’t load properly. You can extract them from your own Nintendo Switch using Lockpick_RCM.
Once obtained, place the keys in C:\Users\YourName\AppData\Roaming\yuzu\keys. After setting up the keys, you can import your game files and configure settings for optimal performance. Keeping Yuzu and your keys updated ensures better compatibility, improved speed, and fewer crashes while emulating Switch games on your PC.
Yuzu requires prod.keys and title.keys to decrypt and run games. Follow these steps:
- Extract keys from your Switch using Lockpick_RCM.
- Copy the keys to C:\Users\YourName\AppData\Roaming\yuzu\keys.
3. Import Games into Yuzu
- Open Yuzu Emulator.
- Click File > Load File and select your XCI or NSP file.
- Alternatively, add a game directory by going to File > Add New Game Directory.
4. Configure Game Settings for Better Performance

- Enable Asynchronous GPU Emulation to reduce stuttering.
- Adjust CPU accuracy settings for stability and speed.
5. Run Your Game
- Select your game from the Yuzu library.
- Click Start to launch it.
- Wait for shader compilation, which improves performance over time.
