I finished my Centipede MAME cabinet today and ran into an issue with the trackball. The trackball gets "stuck" (I don't mean physically like the ball gets stuck - e.g. in Millipede your cannon doesn't move) at times when moving to the left. In order to get "unstuck" you have to put some English into it. All other directions work flawless: north, south and east.

Does this sound familiar or any hunch as to what the problem might be?
 
It souds like either your beraings are shot, allowing the ball to slip past; or your reader board has some cold solder joints preventing the spinning encoder wheel from being seen. Either way you need to take apart the trackball and take a look.
