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.
