So, awhile ago I bought a Championship Bowling converted from a Centipede. But just the other day I found it for MAME, I noticed something a bit different from the version I was playing on mame and the original board I own (which isnt installed in anything so I cant go back and look it over. But from the pictures I have, the background is not the same color, on Mame its black, but on my board, its green. look for yourself in the pics below. I wonder if maybe there were different versions of this game.
