In The Force Unleashed two designs are shown - a Wookie Flag, which looks like a royal flag, and the 'flag' of the Rebel Alliance.
This game takes place in between Episode 3 - Revenge of the Sith 2005 and Episode 4 - A New Hope 1977. In this video game we see the origins of the Rebel Alliance. Ironically Darth Vader is a catalyst for the movement.
