You forgot to add an option on Tron in MAME (discs of Tron, Tron, Tron Mahjong...). Ironic, I just watched Tron Legacy on my ipad flying home two nights ago. After 5 times watching it, it's not as bad of a movie as the first time I saw it and my impression. Tron LE captures it so perfectly. Just wish quotes in game more spread out. Watch the movie then play Tron pinball. Most of the quotes are from the first 10 minutes of the movie.
