I also have a Pool Sharks pin. Bought it about a year ago. There were several issues it had. Several features did not work, the previous owner was not very good at diagnostics and was replacing each part. I was able to trace the issues to a wire pulled out of a connector causing several features on a matrix line to not operate. Simple fix. The top ramp diverter assembly parts had been taken, I assume to fix another PS. Another pinsider made a 3d file for the diverter plastic and I was able to get the diverter back up and fully functioning. I play this game regularly and enjoy it.
