  • Map the GamePad buttons to the wanted keys.
    • Left-click on the button to detect the input (keyboard or mouse).
    • Right-click on the button to show a pop-up menu. The Clear, vJoy, Detect and Mouse option could be used to set a key.

vJoy (virtual joystick for Windows)

  • Download vJoy from the Official Site.
  • Read the How to Install steps.
  • Before launching UsendMii Configure the vJoy Device. UsendMii will pick the first device that is available. Only buttons and axes (X, Y, Z, Rx, Ry and Rz) are supported.

How Does It Work

  • UsendMii is a HTTP server that delivers Web content to the Wii U Internet Browser software.
  • The Internet Browser uses specialized JavaScript to obtain button states of the GamePad.
  • The button states are converted to JSON and sent via a POST request to UsendMii.
  • When received, UsendMii will simulate keystrokes, mouse motions, or button clicks.



  • Mac OS X version is now available (some functionalities are missing).
  • Key mapping could be saved and loaded from XML files.
  • Added touch screen (Left, Right, Up and Down).


  • Seeking an MP4 video is now working.
  • Added support for mouse wheel, mouse X buttons and vJoy (virtual joystick).


  • Viewing MP4 video from a folder on your PC is now possible.
  • Stick could be used for moving the cursor.
  • Now using XMLHttpRequest instead of jQuery.


  • Mouse buttons could be simulated.
  • Input could be used when the touch screen is touched.
