Mega Man 3 Cheats

Press ''right'' on controller 2 and mega man can jump much higher and walk across the bottom of pits. For invincibility have mega man jump into a pit, then press ''right'' on controller 2. Wait for the energy bar to go black and jump out of the pit. Mega Man will be invincible as long as he does not obtain any energy. Once invincible, the arm cannon no longer works but weapons obtained from bosses do.

On controller 2: Push and hold Up and A.

NOTE: Does not work on all enemies, but it does work on almost all bosses.

In order for this trick to work, you must have Spark Shooter (SparkMan's weapon), but must not have defeated ShadowMan, the Robot Master who gives it to you. Go into the menu and point to Spark Shooter. While the cursor is on Spark Shooter, press right on the D-Pad. Rush's picture will appear instead of Spark Shooter's picture. Select this, and you will now have Rush Marine with an empty meter. Now, go pick up a weapon capsule or weapon pellet to fill the empty meter with. Once it has a little bit of energy, the Rush Marine option will now permanently appear on your weapons list, even when you deselect it.

Normally, to obtain the Rush Jet, you must get it by defeating Needle Man. Instead you can go to Shadow Man's stage and defeat him so that you acquire the Shadow Blade from him. Then, go to any other level and find a weapon energy refill capsule. Don't pick it up yet. Instead, open up the pause menu and highlight the Shadow Blades. Then press Right on the D-Pad, then press start to unpause the game and you should now have an empty weapon energy meter. Grab the weapon energy capsule and you will now fill up the empty energy meter. This energy meter is the Rush Jet. You can now summon the Rush Jet anytime.
