GamePad Viewer on Nintendo Switch // NO MODDING OR HACKING YOUR SWITCH!
There are a lot of really bad YouTube videos out there of people trying to use GamePad Viewer to make the Nintendo Pro Controller show as an overlay while streaming. Unfortunately they require modding your Switch, which is totally unnecessary.
This video is a quick demonstration of the Pro Controller inputs being shown on the Switch, using Jayraydee's awesome Pro Controller skin, without modding/hacking your Switch.
