Metroid Glitches
1. Door Jump- Stand in a Blue Door and have it close on you. Than rapidly hit Up and Down on the
D-Pad. You should move up. (Do not go into Morph Ball form or you will get stuck) When you reach the wall above the door
use the Jump button to gain height. Once the Screen stops scrolling up rapidly hit Up and Down a few times again.
This is the only way to access Secret Worlds in the NES Metroid.
2. Spinner- When an enemy is on a door or destroyable block either open or destroy it and the enemy
will rapidly spin in mid-air until it regenerates.
