If you take a look at gameport_measure_speed() in gameport.c you will see that it counts cycles for timing, which obviously does not work that well when CPU frequency changes. The bugs have been opened in bugzilla/reported on lists ages ago but nobody stepped up to fix that. > The obvious workaround for such an ensuing dearth of hardware support > could be USB 15-pin gameport adapters - but are they even supported on > Linux?

I really do not care about Microsoft and favors, I just go by the fact that this hardware is becoming naturally extinct. And not only hardware, but also software that uses it. Do you still play a lot of games with joysticks on such hardware?
