Regarding the Ni Wumph board for sys1 pins... two yrs ago i bought two of them... One ended up in my Solar Ride, and the other i tried in Roller Disco, which i promptly pulled out and put the original cpu back in. It seems they changed some of the rules for some games, so some of the features worked differently.. eg; on Roller Disco, normally when xtra ball is won it holds any bonus multipliers won and carries the over to the next ball... the Ni Wumpf board resets multipliers for every ball. Also the advance multiplier lanes usually score 20,000 when 5x bonus is lit on the original board, and only 5000 for the Ni Wumpf!! And the bonus countdown is painfully slow!!! Had similar issues with the Ni Wumpf when tried in my Buck Rogers.

Well that was over two yrs ago... maybe they've changed the software since then?? Or maybe i'm being too picky, lol.
