X-Men: Mutant Apocalypse

A side-scrolling action game wherein Apocalypse is the mastermind behind an anti-Mutant island complex, but it turns out that it was Dr. Wily the whole time!

Incomplete Anti-Piracy#

The game does not contain SRAM by default, but still tries to write to it whenever an enemy gets hit. Numerous areas of SRAM starting from $306000 gets written, which if successful, increments the value in 0x1FBB by one. It doesn't seem to have any other meaningful impact, although due to being mentioned in Nintendo documentation as having anti-piracy checks, it is possible that an anti-piracy check was planned to be implemented, but was not properly added.

Object Viewer#

An object viewer identical to the one found in Mega Man 7 and Rockman & Forte is hidden in the game. Use either of the following code sets to access the viewer when the game boots up.

Controls:

• Left / Right: Cycle through object animations.
• A + Directions: Move object around.
• B + Up / Down: Cycle through objects.
• X + Directions: Flip object horziontally / vertically.
• Y: Play current animation.
• Directions (2P): Move cursor.
• Y + Left / Right (2P): Change width of cursor.
• Y + Up / Down (2P): Change length of cursor.

Sound Test#

Use these codes to access a simple sound test after the Marvel Comics logo fades out.

Note: While the Music selection goes up to 30, playing any track past 2A will freeze the game.
