Get the item you want from FlipTop/Eddie

FlipTop/Eddie appears in certain empty rooms and will eject a random item to you when you are close by. Walk up to him to get him to stop, then quickly move away. If you don't get the item you want, exit the room and return. As long as you don't pick up the item, Eddie/FlipTop will reappear with a new item.

Kill Dr. Wily

After beating Wily Machine 4, you can cast Rain Flush at the right time to kill Dr. Wily. The ending sequence will not play.

Pharaoh Shot Energy Trick

The Pharaoh Shot only uses energy when you either press or release the B button, so you can have unlimited Pharaoh Shots doing the following trick.

At the weapon menu highlight the Pharaoh Shot, press and hold the B button, then resume playing the game. You will start charging your shot as if you had already fired it. Run the charged shot into an enemy so that you don't release the B button. This will hurt the enemy but not drain any energy from you weapon meter.
