I understand that when configuring the GCpad, you must hit 'Standard Controller' as the type and 'Keyboard/0/Apple Internal Keyboard/Trackpad' as the source. I have tried EVERYTHING to enable the internal keyboard on my Macbook Pro running iOS X (10.12.5) within the dolphin emulator.
I just downloaded the dolphin emulator yesterday and dumped two of my gamecube games- Tony Hawk's American Wasteland and Animal Crossing.
