There's 2 sets of sound/music ROMS for Rollergames as well.
The German distributor didn't like the original ROMS, and told WMS they wouldn't buy any if they came with the ROMS that were in the test games.
So, WMS made a 2nd set of sound ROMS. I don't find them to be that much different than the regular ones, but I have been told by others that they are different, so perhaps my hearing sucks.
The game in the video is an early production model - has the W logo speaker covers - maybe 200 games made with these. Also is early production because it has the flashers behind the translite - these were cost reduced out of the machine.
The guy playing it is pretty damn good too!
