Interested in both Blitz and MKT but I am surprised to hear you can't get either working on XP. Did you try running them in compatibility mode? I have some games to trade mostly older though. I also have some parts left from my cabinet. 1 joystick think it is a happs super, a ton of yellow push buttons, 2 guncon2 guns. As far as games I have freedom force, World of Warcraft, City of Heros. If nothing interests you let me know and I will look to see what else I have.
