What Causes of ‘A Fatal Error Occurred When Running Fusee’ Error?
All Heading
The “a fatal error occurred when running Fusee” error on the Nintendo Switch typically occurs due to one or more of the following reasons:
- Corrupted or incompatible files: If the necessary files for running the Fusee payload are corrupted, missing, or incompatible, the error may occur. This could happen during the initial installation of custom firmware or when updating your modded system.
- Issues with the SD card: The SD card used to store the modding files may have formatting issues, bad sectors, or be improperly inserted into the console. These issues can prevent the console from properly reading the required files, leading to the error.
- Outdated software: The error may occur if your custom firmware, homebrew applications, or bootloader software (such as Atmosphere or Hekate) are outdated. Keeping your software up to date is essential for compatibility and stability.
- Conflicts with other homebrew applications or custom themes: In some cases, conflicts between different homebrew applications or custom themes installed on your Nintendo Switch can lead to the error. This can happen if the applications or themes are not fully compatible with each other or with the current version of the firmware.
- Auto RCM issues: Auto RCM is a feature that allows the console to boot directly into the custom firmware without the need for a payload injection each time. However, enabling or disabling Auto RCM incorrectly or having a faulty Auto RCM implementation can cause issues and result in the error.
By identifying the potential cause of the error, you can take appropriate troubleshooting steps to resolve it and get your modded Nintendo Switch running smoothly again.
How to Fix A Fatal Error Occurred When Running Fusee?
Below are some methods that you can apply to fix the “a fatal error occurred when running Fusee“:
1. Check Your SD Card
To troubleshoot the “a fatal error occurred when running Fusee” error, start by examining your SD card. Ensure that it is formatted in the correct file format. While different emulators support various formats, FAT32 or NTFS are generally safe options. Additionally, corrupt SD cards can trigger this error. To confirm the integrity of your SD card, format it and test it with another device. This step will help ensure that everything is in order.
2. By Updating Atmosphere and Hekate
Keeping your Atmosphere and Hekate software updated with the latest stable builds is crucial to ensure compatibility with the most recent Switch firmware. Make sure to update the fusee.bin file, as well as the configuration files. If there have been any software version changes, updated configuration files will be required. Moreover, after the update, verify that all the necessary files for the programs to function properly are present on your Switch’s storage drive or memory card. Updates often remove configuration files necessary for the emulator to run smoothly.
3. By Replacing Fusee Files
In addition to replacing configuration files, another troubleshooting step is replacing the currently used fusee-primary.bin file with fusee.bin and the fusee-secondary.bin file with package. This action helps ensure that the emulator’s configuration is correct and can potentially resolve the error you’re encountering.
4. By Disable Auto RCM
Hekate includes a feature called auto RCM, which automatically boots your console into the default operating system if the modded operating system fails to boot. However, there are instances where auto RCM overrides the modded OS and starts the stock OS directly. To check if auto RCM is causing the error, disable it in the Hekate settings and observe if the issue persists.
Remember to always proceed with caution when modding your handheld console and ensure that you follow instructions from trusted sources. Modding carries risks, and it’s important to be aware of the potential consequences, such as voiding warranties or damaging the console if done incorrectly.
By implementing these solutions and seeking support from the modding community, you can overcome the “a fatal error occurred when running Fusee” issue and continue enjoying your modded handheld console with an extensive game library.
