This is way too funny. I’ve thought about posting on the exact same topic for years.
My brothers and I remember playing a pinball machine in my neighbors basement that had a guy panning for gold on it. I seem to remember him being in the lower left hand corner, crouched down and looking like an old cowboy. I was too young to remember any other details but my older brother says it was definitely an EM and possibly multi player.
We have searched for years and never found anything close to what we remember. The one we remember is not any of the ones suggested above.
