I did a play on that machine and actually managed to beat Vader and Boba with a screwed joystick. Wow! Then I couldn't hit the final torpedo shot on the last level because of that stick. :(

General game questions:

-Does anybody know the levels of difficulty? I know there are Light Lv. 1, 2, 3

-Any secrets? The ones I know of are:

Shooting a high number of turrets on Yavin mid stages and Death Star II level. Hitting all probe droids on Hoth stage 1. Hitting Vader and the wingmen with proton torpedoes. Deactiviating lightsaber when Vader is defeated to get "So be it Jedi".

-What is the highest rank?

I haven't played the 32x version but I would like to find a machine of Star Wars Arcade sometime.
