Instant Boss Kill
When entering the Boss room in stages 1,2, 4, and 5 press the select button to use a bomb (as the door closes on Nova before the screen with the Boss loads) When the screen comes up after entering the door the boss is already defeated. This cheat does not work for stages 3,6 or 7.
