This is a VPX recreation of a 1991 Williams Strike Master Shuffle Alley Bowler. It needs the rom "strik_l4.zip" to run. This is a complete remake by me, not a conversion. Started from scratch.
Thanks to Wildman for the backglass image from the vp9 version.
Flippers move arm left and right. Analog and digital plunger pulls the arm forwards and backwards and starts angle rotation.
