How do I kill andross?

I'll give you a walkthrough. First, destroy the Krazoa's eyes and the diamond on it's forehead. When andross turns around, shoot the crystals on his hands when he lifts them. When he opens his mouth, shoot lasers into his mouth to destroy 85% of the asteroids that he will spit out. When he starts to suck the craft in, use the boosters with y. Don't use all of the booster's power in one go. Hold y, release, hold and release until the power runs out. When the boosters fire up again, repeat the above process. When he stops sucking, shoot his hands again until they are destroyed. He will turn around and start shooting the circle laser again. Dodge this and destroy the eyes and forehead crystal before his missiles are launched. If he launches missiles, fly all over the place until the missiles vanish. When he turns around again, do what you did last time, but if he lifts the hand on YOUR right first, he will fire a circle laser like the Krazoa face does. When he starts to suck, you won't be able to resist it. Falco will fly past and bomb him. Note that when you destroy his hands for the second time, he can't regenerate them unless he sucks you in. Now he can fire missiles, asteroids or suck (which he does anyway, come to think of it). While he fires asteroids, Falco will drop a supply crate. Shoot it and collect the bomb inside. When he sucks, fire the bomb into his mouth. His whole body will become transparent. A meter appears at the bottom of the screen with his face on it. Shoot his brain to reduce the meter. Repeat this process until he dies.

*NOTE* Even if you beat andross, you can't go back to Dinosaur Planet without deleting your game.

Hope that helped you.
