There was a great pinball app called a Pinball Arcade that featured a lot of the old Williams, Bally, Stern and Gottlieb titles. I have it, and it’s great. Unfortunately, Williams/Bally decided not to renew the licensing agreement. Fortunately, I got in before this occurred and was able to download a lot of my old favorites.
