Controller Tray

A Windows system tray application that maps game controller joystick input to mouse cursor movement. Supports both XInput (Xbox) and DirectInput devices, including configurations with dual detached controllers.

Originally created for the Lenovo Legion Go, where one or both controllers can be detached from the main unit.

Features

• XInput support - Works with Xbox controllers and compatible devices
• DirectInput support - Works with generic game controllers
  • Single device mode
  • Dual device mode (two separate joysticks controlling the same cursor)
• Dual stick priority modes - When using two controllers:
  • Stick 1 Priority - Use first stick, fallback to second
  • Stick 2 Priority - Use second stick, fallback to first
  • Largest Movement - Use whichever stick has more deflection
  • Combine Additive - Sum both stick inputs together
• Configurable sensitivity and deadzone
• Axis options - Invert X, invert Y, or swap X/Y axes
• System tray integration - Runs quietly in the background
• Persistent settings - Configuration saved to config.toml

Specific Use Case:

Allows Legion Go controllers to work when detached from device (both or single controller detached).
