Let's select our Dolphin shortcut and select manage shortcut and then configure the controller. Now it's time to start Dolphin! One thing to do before we actually start, though.
If you encounter issues the steam controller forums are a good place to start. I won't be going into detail here about how to install the controller as the process is mostly automated.
If you have a multi-monitor setup or need to have access to other apps while playing, this can be a more convenient way for some people. Alternatively, you can also access the steam controller configuration menus right from desktop mode without having to actually open BPM fully. If you like you can run BPM in a window by going to the setings in BPM and checking the 'start BPM windowed' checkbox under the interface section. Additionally, we will need to use Steam Big Picture Mode (Henceforth referred to as BPM) for any and all configuration as the interface for normal desktop steam is not available. This is because the Steam Controller uses the Steam client to do all the input device emulation and is fully required to use this controller in anything but a basic mouse style mode. Firstly we are going to need the steam client installed.
