Never mind, I just beat "Metroid II." The trick to beating the queen is to hit her with a missile in a certain spot in her mouth. She freezes up for a few seconds each time you do this, allowing you to shoot more missiles into her mouth, which do more damage than just blasting away at the carapace.
Now, does anyone else have a non-"Mario" video game they need help on? I can help you with a lot, plus I'm sure plenty of the other forum users play more than just "Mario" games.
