Troubleshooting Guide

Fix Common Ryujinx Emulator Errors, Crashes, and Compatibility Issues.

Use this guide to identify and resolve the most common issues users face when using Ryujinx. Whether you are setting it up for the first time or experiencing problems after an update, these solutions will help you get back to peak performance and stability.

Troubleshooting Errors

1. Game Not Starting

Check that the prod.keys and firmware are properly installed.
After changing any game files or keys, restart Ryujinx.
Rather than double-clicking the game, select File > Load Application.
Check the game file integrity (.XCI,.NSP,.NRO).

2. Black Screen or Missing Graphics

Change the rendering backend (Vulkan/OpenGL) under Settings > Graphics.
To identify corruption, disable the shader cache temporarily.
Try using lower resolution scaling and the default aspect ratio.
Update your GPU drivers.

3. Emulator Crashing or Freezing

Clear the shader cache for the specified game.
Disable all mods and cheats temporarily.
Update to the most recent Ryujinx build.
Ensure the system meets the minimum hardware requirements.

4. Save Files Not Working

Check the emulator folder’s write permissions.
In portable mode, check for the presence of the saves folder.
As a workaround, consider using Save State.
Avoid switching between profiles without first backing up your data.

5. Audio Delay or Distortion

If an audio backend is available, switch it in Settings > Audio.
Close any other applications that use sound processing.
To improve synchronization, reduce the resolution scale or the load.

6. Slow Performance or Lag

Reduce the resolution scaling and anisotropic filtering.
Ensure that PPTC and Shader Cache are enabled.
To achieve faster read speeds, use SSDs rather than HDDs.
Update to the most recent build or fork.

7. Firmware or Keys Not Detected

Place prod.keys in the appropriate system folder.
Use Tools > Install Firmware and select the appropriate.zip or folder.
Ensure that file names are exact and have not been incorrectly renamed.
After the installation, restart Ryujinx.

8. Game Update Loop or Conflicts

Manage Title Updates allows you to remove previous updates.
Make sure the update files match the version of the base game.
Avoid installing firmware with trimmed XCI files.

9. Controller Not Detected

Reconfigure the device from Settings > Input.
Depending on your setup, choose either “Docked” or “Handheld” mode.
If you are using a gyro, you should enable support through external tools.
Before proceeding with Bluetooth, ensure USB connectivity.

10. GitHub Release Error

This is due to the removal of Ryujinx’s GitHub repository.
It can be safely ignored and has no effect on functionality.
To avoid this error, use GreenDev or other community forks.

11. Setup Incomplete or Files Missing

Re-extract the downloaded Ryujinx zip and avoid running it from protected folders such as Desktop or C:\root.
Ensure that folders such as system, mods, and portable exist.
Confirm that no antivirus software is blocking access.

12. UI Not Displaying Properly

Reduce system-wide DPI settings.
Set Ryujinx to override high-DPI scaling in the compatibility settings on Windows.
Use the most recent stable graphics driver.

13. Mods or Cheats Not Working

Confirm that mods are in the correct directory structure under mods/contents/<title_id>.
Cheats for IPS must match the executable’s build ID.
Move any cheats that are conflicting or unused to a disabled folder.
Double-check .pchtxt headers and formatting.

14. Multiplayer/LDN Mode Issues

Ensure that all players are on the same game version.
Select the appropriate network mode in Settings > Network.
LAN mode can be enabled for same-network play or disabled for internet-based LDN.
Check the firewall and router configurations for peer-to-peer connectivity.

15. Crashes During Shader Compilation

Delete the game’s shader cache and restart.
Ensure that the GPU meets the OpenGL 4.5 or Vulkan 1.2 standards.
To test cache behavior, either enable or disable PPTC.

16. Missing System Version or Firmware Errors

Reinstall firmware by selecting Tools > Install Firmware.
Use an untrimmed.XCI dump or.ZIP file.
Check that prod.keys supports the firmware version currently installed.
