Had an older Doyle kit, 2.0 I think. Fine kit, but there were too many nit-picky things about for me - colors were wrong, Pac plus has a blue maze, patterns were not always accurate. Not sure if these have been fixed in 2.5x but they were there in 2.0. I didn't care for the dozens and dozens of maze variations either.
Switched it out for a High Score Saves Multipac kit, and while it is not quite perfect either, it is pretty darn close! Colors are right, patterns are pretty spot on. I LOVE the fact that I can boot directly into a game! That one thing sold me right off the bat. You can't with the Doyle kit
However, I found Doyle's to be much more stable. My machine hangs on the game menu screen in the HSS kit and I have to turn it on and off again. Despite that, I am happier with HSS.
A plus for Doyle's is it has a burn in protector. I miss that in the HSS kit, but I have the game sound set to 25% in attract mode, and the noise forces me to shut it off if I forgot I left it on.
That said, I don't want sound like I'm under selling Doyle's 96... it is a VERY good kit and many people probably wouldn't bat an eyelash at all the stuff I see. I am an annoying Pac purist!
