@wstanek Thanks, I would like to see that list. In the meantime I found out that Ultimarc's product page actually says that the SpinTrak has "1200 pulses per revolution". But if that's so, then I don't understand why the formula from my link above doesn't get the proper results. No big problem, just more work to find the right values by hand.
My current approach is to try to find and setup the original rotation/movement ratio (e.g. those mentioned above for Arkanoid and Tempest), and then adjust them to my liking.
APB is a good idea. At the moment, I'm collecting the games listed on my link above in two custom collections: driving games and any other spinner/paddle games. Affter that, I'll go through all of them to adjust their analogue settings and test their playability.
