pharmacisticus

Hey sorry to jump this old thread. But to those who are using the happ rotary stick, is it still usable for other games? I'm about to start making a controller and want to know if I can use a rotary happ as the main joystick and still enjoy games like Street Fighter 2? Is the rotary lockable? or is it always on, does this affect normal 4 or 8 way gameplay. Thanks
