PadSquire
Linux and macOS tools for GameSir controllers, so you can configure and update them without Windows.
GameSir's own app only runs on Windows. PadSquire covers the same ground for the GameSir Nova 2 Lite on Linux and macOS: dead zones, button remapping, vibration, profiles and firmware updates for both the controller and its receiver.
It also does something GameSir's app doesn't: a stick check that measures how far each stick drifts and whether it reaches full tilt, then suggests dead zones for your controller.
Unofficial and open source, built by studying how the controller talks over USB and Bluetooth. It installs with one command and updates itself.
