Hey gang this is something I have just spent the last hour or so searching on the forums as this issue has been posted many times for the last 10 years. I just went from a betson imperial trackball to a new Happ 3in LED usb version trackball. I have that lag when playing golden tee and world class bowling. If you give to much forward spin it will lag out for a split second.This is very annoying and makes golden tee unplayable. I'm running Windows 7 MAME version 0.171 the mouse driver says its from mircosoft. I have played with the mouse settings and it still did not help. Reading I came across this from happ as mentioned in some other threads.
