Gradius III - Easy Final Boss

Put the ship in the middle of the screen, near the bottom. The blasts will be unable to hit you. Even better yet, this boss doesn't require you to actually damage it to a certain point, so just stay in this safe zone and it will die after 15 seconds or so.

Change BGM in Stage 3

In Stage 3 (In The Wind), around the T-shaped cliff, you will find an enemy bay against the wall and under a ceiling, which is nearly impossible to hit except with the use of some types of Missiles and the S.Option. Destroy it, and the BGM in the stage will change.
