Thanks for your reply. I am making a rotatable control panel with 3 sides. I have a spinner panel, a 2-player 8-way with trackball, and a 4-way dedicated.
I want to use the 4-way panel for all 4-way joystick games, but also button games like asteroids. I love defender so I've also laid out the panel so this game can be played with the reverse button in the right place. The pac-pro seems to take a fair bit of force to push up and down, and returns to center very quickly when you lessen pressure - strong spring. I was wondering if this might cause issues in gameplay.
Alternative I suppose is to have a 4-way joy and a 2-way joy on the same panel... (starts to look ugly then tho!)
Cheers
