DualShock 4 / DualSense Fix
First, go in Big Picture mode, controller settings, and check the playstation, xbox and generic controller boxes.
Note: No idea if this is a necessary step, but I did it just in case.
Then right click on No More Heroes in your library, properties, and controller. Then disable Steam input.
My DualSense controller wasn’t getting detected no matter what I did until I did this. It’s working fine now.
