I got peeved at the constant crashes from WHDLoad and Pinball Dreams/Fantasies/Illusions and Slam Tilt Pinball when my Blizzard PPC was installed, yet nothing crashes when my Apollo 1240 is plugged in. I tried every setting there was, got updated slaves etc until finally I gave up.
Since I can't go without my weekly fix of pinball, the PPC is up for sale on Ebay ... c'est la vie! - Shameless plug but what the hell!
