I have one of these spinners and I can't get it to work properly. I've tried tweaking the settings many many times, but the results are still poor. Playing Arkanov, for example, the paddle is jittery as it moves in each direction, or it will reverse direction unexpectedly. It's unplayable. Tempest is playable, but still not great. The spinner came with recommended settings for MAME, but those didn't work that well either.
Again - this could be my settings. Does anyone have any advice for me to get it working properly?
