Something simple like Joytokey works for that purpose for anyone who doesn't have a dualshock. In my opinion it's necessary anyway since with default binds the dpad doesn't work on any controller I've tested.

I noticed that, but I wasn't aware it only happens with a ps4 controller. I agree with you; having two actions bound to one input shouldn't be allowed.

I looked, and ds4windows is the only program that I could find to easily bind analog stick axes to both controller inputs or keyboard inputs. So unless there is one that lets other controllers do the same thing, I'd be against allowing it.

Do you use your actual X key? Should I be? I've bound it to L1 for convenience.

I was just testing out ideas for shooting faster, and I ended up using ds4windows to bind Up and Down on the right analog stick to the controller's shoot button and Left and Right to X on the keyboard. Basically let's you shoot as fast as you can move the stick in a circle instead of pushing two different buttons.

Remapping is pretty standard and easy to do with most controllers but this speeds up the first couple bosses a lot and nobody else is doing it so I wanted to ask for some input on whether it should be allowed or not.
