What is sigpatches switch?

Sigpatches for Nintendo Switch are patches or modifications to the operating system that allow the installation and use of custom firmware and homebrew applications on the console. These patches bypass the system's signature checks that usually prevent installation of unverified content, and are necessary for running custom firmware such as Atmosphere, ReiNX, or SX OS.

Sigpatches are specific to the firmware version of the Nintendo Switch, and need to be updated whenever a new firmware is released. They can usually be downloaded from reliable sources online, and installed via a custom firmware or homebrew application.

It's important to note that using sigpatches can potentially void your warranty, and may lead to various risks such as bricking your device or getting banned from online services. Therefore, it's recommended to carefully research and follow the instructions from trusted sources when using sigpatches or any other homebrew software on your Nintendo Switch.
