It can be frustrating to encounter errors while using Yuzu Emulator, but do not worry—each error code has a specific meaning, and the majority of issues can be easily resolved. This guide will help you understand the most common error codes you may encounter while using Yuzu and how to fix them. We have categorized error codes from simple to advanced so that you can quickly identify and resolve the issue.

What Are Error Codes?

An error code is a unique alphanumeric code created by the emulator to indicate a problem. These codes assist developers in diagnosing and troubleshooting issues by identifying the specific component of the program that is malfunctioning. Users can use these codes to report problems, allowing the development team to identify and fix them more quickly.

Key Error Codes

These are the most common error codes indicating missing or incorrect keys.

Solution: Ensure that you have legally dumped the necessary keys from your own Nintendo Switch console. These keys are required for decryption and running Switch games on Yuzu.

Common Error Codes

These errors frequently involve file integrity, missing components, or unsupported formats.

Solution: Make sure your game files are properly dumped from your Switch and that the correct files are in place. Re-dumping the game may solve some problems.

Corruption Error Codes

These error codes are typically associated with bad or corrupt dumps.

Solution: These errors typically indicate that the game dump was faulty. Re-dump the game to obtain a clean copy. You can verify the file integrity and re-download the game if necessary.

General Error Codes

These error codes are uncommon but can indicate problems caused by emulator modifications or external factors.

Solution: Ensure that the NCA file you are attempting to load is properly formatted and supported by Yuzu. If your NCA file is corrupted or incompatible, consider replacing it with a valid copy.

Key Derivation Errors

These errors occur when the wrong key derivation method is used or when keys are missing.

Solution: Ensure that all of Yuzu’s required keys have been generated and placed correctly. For more information, see the key generation guide on Yuzu’s official website.

Internal Error Codes

These error codes are intended for internal debugging and should not affect most users unless you are experimenting with emulator builds or modifying the code.

Solution: These codes are typically informative, and unless you are a developer, you will rarely come across them.
