I want to buy a time crisis gun but first i want some info about it. The one i found on ebay said it's a Light gun for time crisis. Does that mean i will need a certain screen to use it or something? Can 2 connect to the same PS2? how do you connect it? I saw a usb and this other thing, i know where the usb goes but not the other thing, will i need them both? is this gonna work with ALL time crisis games? and is there a wireless controller?
