On SPIKE 2 games there are generally dozens of "Champions" for everything from modes, to multiballs, to even spinner champion. It takes a bit of work, but go into the menus and set the awards to replay for each and every one of these. Also, set Grand Champion to three knocks, high score #1 to two knocks and high score #3 and #4 to one knock. You will have plenty of knockin if you do this. Also, make sure match is at least 10%.

Haha they are loud as hell when they hit the back of the cabinet. You could change it to hit the side of the cabinet. Use a knuckle and tap various places to find one that is not so hollow sounding. Or have it hit the cross member instead of the outside wall of the cabinet.

Personally I love it LOUD.
