help with DS4 deadzone

[domjam]

I recently came back to dolphin after a long break. im having trouble sorting out the deadzone for my DS4 controller. cant seem to get it right. I see there is a config option that brings up a new window that shows all the buttons and has "select" "detect" "operator" and "functions" but I'm not sure what this is for or how to use it. I don;t remember seeing this function before as I have been out of the loop with dolphin for quite some time. if someone could assist me that would be great. and if you need any more info just let me know. thanks.
