I never owned a Game Gear, so the way I got to play this game was a setup me and my friend had. I would buy him a game I wanted, and he would buy a Game Boy game he wanted. Funny enough we both got a Mega Man game during this exchange and a good transaction it was. Not only did I get to play this weird mish-mash of Mega Man 4 & 5, but then I had a sweet Game Boy title to call my own. Funny what we used to do to play.
