All pieces other than the King can promote. Promoting really just changes the piece type (except if the piece already has that power). This is because the pieces can change so often, the promotion rule had to be changed from normal Shogi.
Also, the promotion happens after capturing and is optional unless it couldn't move from where it is standing (like in Shogi). Also, all pieces can always move one space straight forward, no matter what other power it has or doesn't have (the Honored-Horse and Angle-Mover start move more powerful than how they do in Shogi).
