Unused Graphics

Mega Man

Early	Final

This early buster shot based on the NES sprite would get replaced with its equivalent from the first Game Boy entry.

Bosses

Gemini Man

Unused	Used

An odd unused version of Gemini Man's firing sprite with a small, misshapen buster. The version of the frame that is actually used matches the equivalent frame in the NES Mega Man 3.

Spark Man

An unused group of tiles meant for a pose where Spark Man leans backwards. It is unknown what pose these legs were meant to go with.

Shadow Man

Unused	Used

An unused version of the sprite when Shadow Man is about to throw a Shadow Blade. The unused version depicts his arm in a slightly different position compared to the used one.

Unused	Used

An unused version of the frame when Shadow Man is throwing a Shadow Blade. While equivalent graphics were used in the NES Mega Man 3, for whatever reason, this game re-uses the "closed mouth" version of these tiles from his intro animation.

Enemies

Hologran

An unused flashing sprite for Hologran. This was part of an animation that played when a Hologran appeared in the NES game.

Walking Bomb

Unused	Used

An unused sprite for the Walking Bomb jumping, like in the NES version. This game reuses one of its walking frames for its jump animation.

Unused	Used

An unused alternate version of the Walking Bomb doing its thing.

Helipon

Unused	Used

Part of this Helipon sprite is erroneously missing in this game, but graphics for it do exist in the code.

Boulder

In the NES Mega Man 4, the boulders in Drill Man's stage had an additional "burst" effect after they hit the ground, but before split into debris. Here, they just shatter immediately when they hit the ground.

Minibosses

Moby

Teleportation sprites for Moby. In the final game, they are already in their rooms when you encounter them.

Fonts

Debugging Font

Some unused tiles that were possibly used as part of debugging tools.

An unused font that goes from 0 to F, likely a debugging font.

Password Font

Early	Final

An early version of the password font, very similar to the one seen in Wily's Revenge!

Unused Damage Values

By modifying the weapons menu code to have all weapons earlier it is possible to use some weapons on some bosses that would normally be impossible to do, and thus see some unused damage in the game.
