Mega Man 2 is, as you may have guessed, the second entry in a very long-running series. Introducing many new concepts and improving on all the flaws of the original, this game is considered by a number of fans to be among the best of the series.

Hmmm...
To do:
Leftover rooms from Mega Man.

Unused Level Tiles

Metal Man

A tile to be used in the center of horizontal screws with five tiles. Only vertical screws use more than five tiles.

Crash Man

Jeepers.

Hidden amongst the background tiles is what appears to be a Met generator, judging by the Met-sized mouth and (obviously) Met-like features. This is probably the most significant and mysterious set of unused tiles in the game.

Flash Man

Two unused platform tiles. Top-left and bottom-left corners exist as well, which actually were used in a single room.

MegaMan2FlashBG1.png

An unused background tile. While a similar tile with no shadow is used twice in a single room, this one isn't.

Other

Did you mean: 'room', 'emptiness', 'time to spare', 'vacancy'

These katakana symbols ("aki") were used to fill empty spaces in the enemy graphics. They mean, appropriately enough, "emptiness".

Unused Item Drop Code

There is coding in the game for enemies to drop E-Tanks upon death, but the code is typically rendered inaccessible due to its potential game-breaking effects.

Hmmm...
To do:
Find out how to activate this by whatever means.

Unused Level Palettes

Wood Man

Autumn forestPink forest

Wood Man's stage has two sets of unused palettes. Since it is part of the animation space, the palettes will cycle.

A 2011 interview with planner Akira Kitamura sheds some light on this:

In MM2, in the forest at the beginning of Wood Man’s stage, I had [Nobuyuki Matsushima] code it so that if you used Atomic Fire on the trees, everything would burn up and the Batton (bat enemies) would all fly off. Sadly that ended up getting removed from the game. (laughs)

A similar effect would later be implemented in Slash Man's stage from Mega Man 7.

Quick Man

The palette for Quick Man's stage is unanimated. Forcing it to animate reveals that the Force Beams throughout the stage once palette cycled between two frames. This was disabled because it causes problems with the hall of Changkey Makers.

Wily Stage 2

In Wily Stage 2, there is a palette cycle intended for one more frame of the turbine cycle, which would make them rotate a bit slower.

Unused Sounds

There are three unused sounds, and it's hard to see how they could fit in the game. Edit offset x3DC59 to any of these values, then select Flash Man's weapon to hear them.

Sound ID 22.

Sound ID 33.

Sound ID 40.

Heat Man's Hidden Atomic Fire Sound

When fighting Heat Man, there are two instances when the sound effect for firing Atomic Fire is called: when Heat Man encases himself in fire, and then again when he charges at the player. However, the normal "hit" sound effect lasts enough seconds to overwrite the game's attempt to call the first Atomic Fire sound- only successfully calling up the second usage of the sound under normal circumstances.

Hacking the game (or using a Randomizer) to replace the "Enemy Hit" sound effect with a shorter sound will cause both usages of the Atomic Fire sound effect to play successfully.

Regional Differences

Title Screen

Japan International
This game is too hard Oddly enough, "Normal" is not actually normal.

Rockman 2 has a copyright tag and trademark symbol on the title screen. Mega Man 2 moves all copyright information to the start of the game, and also moves the building down a bit to accommodate the larger title graphic.

Rockman 2 does not have difficulty levels, and is equal to the Difficult mode in Mega Man 2. The Mega Man 2 port found in Mega Man: The Wily Wars has no difficulty selection for all versions.

Get Equipped

In the Japanese version, the "Get Equipped" screen goes by much faster. This is important knowledge for speedrunners of the game.

P as sword? Oh, that makes much more sense

The erroneous "Pass Word" was corrected in Mega Man 2.

Clash or Crash?

Japan International
Clashing all over the place This Robot Master has performed an illegal operation and will be shut down. Wow, that joke was so old, it's pungent.

Crash Man is known as Clash Man in Rockman 2. It's likely the name was always meant to be Clash Man, as it is kept in Mega Man II (GB) in all regions, though Mega Man: The Power Battle goes with the localized name in the international versions.
