This trick requires the Jewel Satellite. At the beggining of Hornet Man's stage, move to
the right until you reach the first ladder. Without destroying the potted plant robots,
activate the shield and stand on the second platform in between both the robots. If you
remain standing there, the missiles will be destroyed and the screws will automatically
land on Megaman. This also increase your kill count for the "Destroyer" achievement.

In the first Dr. Wily stage, after the check point there are six pipes. Two of them have
weak respawning enemies. Use Jewel Satellite, and stand on top of the first set of pipes.
You will occasionally get extra lives and a lot of Bolts. You can use this trick to
replenish lives lost from the puzzle that is up the ladder. This also helps when
completing challenges. Note: This requires a lot of time.
