Mega Man 2 is a platforming game for the Nintendo Entertainment System.

Following the gameplay of the first Mega Man game, Mega Man 2 has new features, like Robot Master stages increased from 6 to 8, E-cans that replenishes health to 100%, and support items/platforms 1, 2, and 3.

After his defeat, Dr. Wily created his own Robot Masters and continued his desires for world domination. Mega Man is the only one who can stop the evil scientist once again. But before he could reach him, he needs to defeat Dr. Wily's Robot Masters and obtain new powers from them.

What the hack contains:

- Minor text edits
- Slightly altered title screen
- The game now uses SRAM

The main feature of this hack is that the password system has been replaced with a save system. Whenever you complete a stage, the game will save the completed stage, your lives, E-Tanks, and the special items you obtain from Dr. Light.

RetroRain chose to call this hack Mega Man II: The Mystery of Dr. Wily, because the Japanese version is called Rockman 2: Dr. Wily no Nazo, which means "The Mystery of Dr. Wily" in English. So, this patch is simply an update to the English Mega Man II that was released.
