Alright, so I've installed project 64, launched Ocarina of Time and everything works fine except for that I can only use the keyboard for controlling.

I have a fully working Logitech Extreme 3D joystick. I choose it in the configure input menu as a game device but when I try to set controls instead of being able to assign a joystick function when you I the control field with my mouse it sets it to "S0+" and when I hit another field it says that the control is already taken as it try to set it S0+ as well.

So how can you properly setup a joystick?
