after you get ball lock before you shoot the cannon. If you shoot the left saucer it should give you database it only is available after lock is lit. the saucer is also important lock for multiball. It pops up with a ton of options it randomly selects if it gives u points it says "fake points" the points are in 500k and 1 mil and 3 mil. You can get extra ball via the database, specials, security pass, and also video mode. Any other questions and I'll try to answer them T2 is one of my favorites and my fiancees father owns one so i play it all the time.
Good luck
