checked-no =>Stage Practice: On the title screen, hold <A>+<B>+<C> and press <START> to make a Practice Mode option appear. In Practice Mode, you can play through almost any non-boss level of the game. =>Bonus Round Extra Lives: After completing any stage, you'll have the opportunity to earn extra lives in the bonus stage. As you fall from the top of the skyscraper, kill ninjas to earn extra lives. Kill all 50 to earn 3 extra lives, 49 for 2 extra lives, or 48 for one extra life. In addition, if you kill NO ninjas while falling, you'll automatically receive one extra live. However, killing any number between 1 and 47 will only award you bonus points. =>Boss Point Bonus: Reduce a boss's energy down until he only has one or two bars remaining, then use the ninja magic to kill him with one second left on the timer. You should receive a large (200,000 point) bonus. This may not work on the final boss.
