I had the fortune of finding a Jokerz! last night. Had to drive 14hours round trip and cross the border to do it, but I'm officially in the club.Jokerz! is one of my all time favorites from back when I was an arcade rat in the late 80's and I hadn't played one since then. Playing my first game today sure brought back a lot of memories and it was great to find the game is just as much fun now as it was then. Can't wait to restore this one back to its former glory.

Mine is yellowed too, but it looks to be pretty easy to find a replacement. Try Bay area amusements or Marco Specialties.
Mine has both left and right ramps so warped that I can't believe a ball will even roll up them. The previous owner thought they were molded this way on purpose but the walls and floor of the ramp are almost "W" shape from the heat of the lamps underneath. I'm going to try hitting them with a heat gun before I pull the trigger on new left and right ramps.
On a side note...has anyone tried this full sized Mylar printed overlay. If so how was install? Recommend it? Pics of it on your game?
