Power-up Arm Weapon:
After you die on a stage, the "Game Over" screen will appear.
Press B to continue. Die and continue two more times at the
same stage. At the third continue, the screen will change
to Dr. Light's laboratory. He will have just finished developing
the Turbo Accelerator for your arm weapon and he will give it to
you. Die and continue again on the same stage and he will give
you another Turbo Accelerator item for even faster fireball
shooting!
