What issues did you have with the HH CPU from Ni Wumpf ? I'm interested as I was thinking of getting one and yours is the second Ni Wumpf in a HH that is not 100%..
Plays the game start music at the start of every ball 
Also scoring is different.
Yes I found the scoring different when in attract mode. Dont know if it is only the version of software I have and if it has since been revised and fixed.
For example if only one player had played the normal sys 1 shows the actual final score in player 1 and in player Nos. 2, 3 & 4 it reads 000000, NiWumph shows only a single 0 in player 2,3 & 4 displays. Also noted that when the game ends the NIWUMPH flicks to High Score to Date immediatly instead of staying on the final players scores for a few seconds so that you can see if you have matched or not.
Anyone know if this was fixed in later software revisions?
