This is a hack of the JP version of Megaman called Rockman.Rockman TP is a boss rush version of Rockman 1. The game is a similar boss rush Mega Man 1 hack called Mega Man Showdown.
Boss AI’s have changed. Weapons AI’s are also modified. The boss weak points are reversed order. In Wily Stages, you still fight these robot masters before you take on Copy Robot and Dr. Wily. Fighting with the Yellow Devil boss is much more challenging than Mega Man Showdown I.
