How To Fix Cemu Emulator Crashes On Launching Games?

If you’re experiencing crashes with the Cemu emulator when launching games, you can check system requirements, update Cemu and graphic drivers, and set the correct MLC path. Moreover, you may also reinstall Cemu, and delete the Precompiled Shader cache.

Below is a detailed explanation of all the above-mentioned fixes:

1. Check System Requirements

Ensure that your system meets the minimum requirements to run Cemu and the game you are trying to launch.

Cemu Minimum System Requirements

  • Requires a 64-bit processor and operating system
  • OS: Windows 10 64 Bit, Windows 8.1 64 Bit, Windows 8 64 Bit, Windows 7 64 Bit Service Pack 1
  • Processor: Intel Core 2 Quad CPU Q6600 2.40GHz (4 CPUs) / AMD Phenom 9850 Quad-Core Processor (4 CPUs) @ 2.5GHz
  • Memory: 4 GB RAM
  • Graphics: NVIDIA 9800 GT 1GB / AMD HD 4870 1GB (DX 10, 10.1, 11)
  • Storage: 10 GB available space
  • Sound Card: 100% DirectX 11 compatible

2. Update Cemu And Graphic Drivers

Ensure that you’re running the latest version of the Cemu emulator as updates often include bug fixes and performance improvements. Also, update your graphics card drivers to the latest version available from the manufacturer’s website.

To update Cemu and your graphics drivers, follow these steps:

Update Cemu:

  • Visit the official Cemu website to download the latest version of Cemu.
  • Extract the downloaded files and replace the existing Cemu folder with the new one.
  • Launch Cemu and check for any updates within the application.

Update Graphics Drivers:

  • Visit the official website of your GPU manufacturer (Nvidia, AMD, or Intel) to download the latest graphics driver for your system.
  • Uninstall your current graphics driver using Display Driver Uninstaller (DDU) if available.
  • Install the new graphics driver and restart your computer.

3. Set The Correct MLC Path

Cemu requires a correct MLC (Memory Layout Control) path to function properly. Verify that the MLC path is set correctly in Cemu’s settings. If not, browse and set the correct path to where your MLC folder is located.

To set the correct MLC path in Cemu:

  1. Open Cemu and navigate to Options > General settings.
  2. Locate the MLC Path setting in the general settings tab.
  3. Click ‘Browse’ next to the MLC path field.
  4. Choose or create a directory for your MLC path where Cemu will store system data.
  5. Select the folder and press OK.
  6. Save your settings and restart Cemu for the changes to take effect.

4. Uninstall And Reinstall Cemu

 If a specific game is causing the crash, try reinstalling it. Make sure all files are placed correctly so that Cemu has full read and execute permissions. This can sometimes resolve issues with corrupted game files.

To delete and reinstall Cemu, follow these steps:

  1. Uninstall Cemu:
    • Go to your computer’s Control Panel and select “Uninstall a program.”
    • Find Cemu in the list of installed programs, click on it, and then select “Uninstall” to remove the emulator from your system.
  2. Delete Cemu Files:
    • After uninstalling Cemu, manually delete any remaining Cemu files or folders from your system to ensure a clean removal.
  3. Download the Latest Version:
    • Visit the official Cemu website or GitHub page to download the latest version of Cemu.
  4. Install Cemu:
    • Once the download is complete, extract the files from the downloaded archive.
    • Run the setup file and follow the on-screen instructions to install Cemu on your system

5. Delete The Precompiled Shader Cache

 Corrupted shader caches can cause crashes. Navigate to your Cemu folder and delete the ‘precompiled‘ folder inside the ‘shader cache‘ directory.

Cemu will recompile the shaders next time you run the game, which might take a while, but it can fix crashing issues.

6. Check Your Controller Settings

Issues with controller settings, particularly with SDL (Simple DirectMedia Layer) controllers, can cause crashes. If you are using an SDL controller, try disconnecting it and restarting your computer.

After your PC has booted, plug the controller back in and ensure it is configured correctly in Cemu’s input settings.

To check your controller settings in Cemu:

  1. Launch Cemu and go to Options Input settings.
  2. Select your controller in the dropdown menu.
  3. Review and adjust the button mappings as needed.
  4. Configure deadzones and ranges for sticks and triggers if necessary.
  5. Save the configuration.
  6. Test the controller in a game to ensure it’s working correctly.
