Overview
Allow Ryubing to access GameCube controllers in their exclusive mode like Dolphin and Yuzu.
Smaller details
The functionality of both is somewhat different in that Yuzu allows remapping and Dolphin doesn't but the basic idea of native support is the same.
Nature of request
Adding support for GCC adapter to function like it does on an actual Switch.
Why would this feature be useful?
Just makes it so no messing with stick ranges, x-input modes, etc. It's much cleaner and simpler. I use it all the time whenever I can, many do.
