One problem was that all kinds of joysticks needed `` calibration '' . This was true even for arcade-style ones .
Its analog nature has also been the cause of many problems e.g. all kinds of joysticks needed `` calibration '' , even arcade-style ones since no game controller and no joystick produced the same measurements each time , but they were dependent on the exact way acquisition was made and even on the CPU 's speed in some rather poor designs .
