Mega Man/Cheats

The Select Trick
When fighting a boss, you can score multiple hits with the same shot by pausing the game after the first "hit". After the boss has stopped flashing, quickly hit select to unpause the game and then again to pause it again. You will score an additional hit. Keep hitting select until the boss is defeated. You can beat many bosses with one shot this way. This does NOT work with the standard arm cannon.

A less notable, but still occasionally useful, consequence of this is that when you press Select when Mega Man is hit, it will reduce the brief "knockback" period.

Turbo Arm
If you are using a controller with a Turbo capability (or an emulator that does the same) and activate the Super Arm weapon, sometimes you can pick up and throw blocks without the block actually disappearing. This comes in handy when fighting the boss at the end of the third leg of Dr. Wily's Castle.

Iceman glitch
There is a point in the Iceman stage where you try to get a 1-up but often miss it. When you drop down to the next screen (the one before the Big Eye), use your magnet beam and try to climb your way up and try to hop onto the off-screen platform where the 1-up is supposed to be. The moment you step on it, the screen will glitch and show you falling to the screen below and avoiding the Big Eye in the process.
