This is a ROM hack of the original Mega Man (USA) game for the NES, created by Dragonsbrethren. It's not an original Capcom release but a modification of their existing game. Version 3.0 suggests several updates and potential modifications to the gameplay.  The ~Protoman - The Red Bomber designation indicates that the hack might focus on Protoman as a playable character or significantly alter the storyline, focusing on that character.  Gameplay would retain the foundation of the original Mega Man but offer changes implemented by the hacker.  No information available on the creator's company, if any.
