If you head over to the mamewah homepage, Minwah (the guy who developed Mamewah) made a modified mame build called shiftermame specifically for use in a driving cab with a 2 position stick like Pole Position. Its available to download from the site and will save you a whole load of aggro when trying to get Mame Pole Poition to run properly using the original 2 position shifter rather than a keyboard.
