How to use a keyboard?

[JosJuice]

Click the Controllers button in the main window to go to the controller configuration. If GameCube Controllers > Port 1 (at the top of the window) isn't set to Standard Controller, set it to that. Then, press the Configure button next to Port 1. A window will appear that shows all buttons that you can map. In the Device dropdown in the top-left corner, select your keyboard if it isn't selected already. You can map buttons by first clicking on the button in the window and then pressing the keyboard button you want.
