Hint: Hidden balloon

To find the hidden balloon, go across the top part of Pharoah Man’s level but do not enter the pit when it appears. Instead, use Rush to get across it, then go right and you will reach more quicksand. Keep going to reach some platforms. There will be a small container marked with a B. This is the balloon.

Hint: Hidden wire

To find the hidden wire, begin game play on Dive Man’s level. Fall into the small pit that appears soon after the continue point. Avoid the spikes that line the walls and fall all the way down. A container marked W can be found once you reach the bottom. This is the wire.

Hint: 2-in-1 Pharaoh Buster

After the Pharaoh Buster is charged you can run it into an enemy, and when its gone, release the button and shoot it again.

Hint: Defeating Dr. Wily in the final battle

Most weapons are not effective against Dr. Wily in the final battle. Only two are effective – the Pharaoh Shot and Ring Boomerang. The Pharaoh Shot works the best. You can charge it up by pressing B and release it in six directions. When it is charged you can run into Dr. Wily with the power-up shot above your head, then shoot it again by releasing B. You will be able to defeat Dr. Wily with the Ring Boomerang, but it takes a lot longer and you must not miss him at all. After defeating Dr. Wily, the game will end.
