How to Install Sigpatches in Nintendo Switch – Complete Guide

Nintendo Switch, the popular gaming console, offers a versatile gaming experience for players around the world. However, some users may encounter limitations when attempting to install and run custom firmware or homebrew applications on their Switch consoles. One crucial step to overcome these limitations is installing Sigpatches, which enable the installation and execution of unauthorized software. In this comprehensive guide, we will walk you through the process of installing Sigpatches on your Nintendo Switch, allowing you to unlock a broader range of possibilities on your console.

Understand Sigpatches

1. Understand Sigpatches

Sigpatches, also known as Signature Patches, are small modifications to the Switch’s operating system that disable the signature verification process. By disabling this verification, Sigpatches allow the installation and execution of custom firmware, homebrew applications, and games that have not been officially approved by Nintendo.

2. Determine the Firmware Version

Before proceeding, it’s essential to determine the firmware version of your Nintendo Switch. Sigpatches are specific to different firmware versions, and using the wrong ones can lead to compatibility issues or even system instability. To check your firmware version, go to System Settings, navigate to System, and check the System Version number.

3. Find the Correct Sigpatches

Once you have identified your firmware version, you need to find the appropriate Sigpatches for your Nintendo Switch. Several online communities and forums dedicated to Nintendo Switch hacking and homebrew development offer Sigpatch packages for different firmware versions. Visit reliable sources such as reputable Switch hacking forums or trusted homebrew websites to download the appropriate Sigpatch files.

4. Prepare the Required Tools

To install Sigpatches on your Nintendo Switch, you’ll need the following tools:

    • A computer with internet access
    • A compatible USB-C cable
    • An SD card reader

5. Backup Your SD Card

Before making any changes to your Nintendo Switch, it’s crucial to back up the contents of your SD card. Connect your SD card to your computer using an SD card reader and create a copy of all the files and folders stored on the card. This step ensures that you can restore your data in case of any issues during the installation process.

6. Copy Sigpatches to Your SD Card

Once you have downloaded the appropriate Sigpatch files, extract the contents of the archive to a folder on your computer. Locate the “atmosphere” folder on your Nintendo Switch’s SD card and copy the Sigpatch files into the “atmosphere” folder. Replace any existing files if prompted.

7. Safely Eject the SD Card

After copying the Sigpatches to your SD card, safely eject the card from your computer to avoid data corruption. Properly ejecting the SD card ensures that the changes are saved correctly.

8. Insert the SD Card and Boot Your Switch

Insert the SD card back into your Nintendo Switch console and power it on. Launch your preferred custom firmware, such as Atmosphere or SX OS, by following the appropriate instructions for your firmware setup. The custom firmware should detect the Sigpatches and apply them during the boot process.

9. Test Homebrew Applications

Once your Nintendo Switch boots into the custom firmware, you can now test the installation of homebrew applications or games that were previously restricted. Launch your preferred homebrew application or game loader, and if the installation was successful, you should be able to run unauthorized software on your Switch.

10. Keep Your Firmware Updates 

As the Nintendo Switch receives regular firmware updates from Nintendo, it’s essential to stay vigilant and ensure compatibility with Sigpatches. When Nintendo releases a new firmware update, the Sigpatches for that specific version may need to be updated as well. Stay connected with the Nintendo Switch hacking community to access the latest Sigpatches for new firmware releases.


Installing Sigpatches on your Nintendo Switch opens up a world of possibilities by allowing the installation and execution of custom firmware, homebrew applications, and unauthorized games. However, it’s crucial to understand the risks associated with unauthorized software and ensure that you only download Sigpatches from trusted sources. By following this complete guide and staying up-to-date with the Nintendo Switch hacking community, you can enhance your gaming experience and explore a wide range of homebrew applications on your console. Remember to proceed with caution and be aware of the potential consequences of modifying your Nintendo Switch.
