In the arcade version, if you select "new arrangement" about 40 times, eventually you get to chose the map order when you start your game. At the end of the game, when your score is displayed there are three boxes at the top of the screen. The bottom box says "all maps" meaning you can select from 40 or so map orders. Does anyone know how to unlock the features of the other two boxes?
Does anyone know how to unlock the wr-03 ship?
