Some questions about DOOM 64's settings

[LucidLocomotive]

For controller settings, there are 3 turning styles: yaw, roll, and reverse. I've tried all 3 but I cannot notice any difference between them. What are these supposed to do?

 

There is "move sensitivity" and "turn sensitivity", but then there is also "sensitivity" just plain. What does that one do? Why are there different ones? One for left stick and one for right stick I understand, but then what is the general one? is that for the buttons?

 

What settings should I do for PS4 that will perfectly emulate the movement/turning feeling/sensitivity from the Doom and Doom II PS4 ports?
