  • Rockman 3 (in Japan)

Freeze Opponents

Hold Up and A on controller two to freeze opponents. This cheat will not work on the Mega Man 2 bosses that you are up against after defeating the eight robot masters. Instead, it will freeze you and not your opponent.

Slow Motion

Hold Up on controller 2 for slow motion.

Higher Jumping

Hold Right on controller 2 to jump higher.

Walk through pitfalls

Hold Right on controller 2 to walk over pitfalls. This also allows you to jump higher to get out of pitfalls. This cheat will only work of the pitfalls are fairly long.

Invincibility

Hold Right while jumping into a pitfall and intentionally get killed by an enemy in the pitfall. When you hear the sound to indicate that Mega Man has died, jump out of the pitfall and you will be invincible as long as an energy booster is not collected. You cannot use your regular gun while invincible but the spark shot and needle are still active.

Hint: Suggested opponent order

Magnet, Hard, Top, Shadow, Spark, Snake, Gemini, Needle, ‘Spark’, ‘Shadow’, ‘Gemini’, then ‘Needle’.

Glitch: Misspelling

After defeating Shadow, Gemini, Spark, and Needle, there will be an intermission sequence in which Dr. Light is talking to Mega Man. at one point, he will say ‘Dr. Wiley took GAMMA’. In all of the other Mega Man games on NES/Famicom, Dr. Wily is spelled without an ‘e’.

Hint: Get Rush Jet immediately

To get Rush Jet without having to defeat Needle Man, you must first defeat Shadow Man. Then, in the next stage, pause the game, highlight Shadow Man’s weapon, and press Right. No weapon will be highlighted, but you will see Rush’s icon above the next symbol. Press Start to unpause the game and you will then be using the Rush Jet, except with no energy. Collect a weapon capsule in this form and then use any amount of its energy. Pause the game again and you will see that the Rush Jet is freely accessible from this point forward. You can also do a similar trick to get the Rush Marine, but you will need to defeat Spark Man. You can only get the instant access for it if you are in Gemini Man’s stage as the Rush Marine can only be used under water.

Hint: Protoman’s whistle

Press Start to pause the game while Protoman whistles to hear the full tune. Note: This must be done while Megaman is still controllable.
