I played this through the first Sega Genesis Mini. This is a compilation of the first three Mega Man games from Nintendo Entertainment System. Plus a bonus game that composite aspects from all three Mega Man games. It also was among several games exclusive in the United States through Sega Channel. I also played the first three Mega Man games from NES through Mega Man Legacy Collection 1. I would say it's a little better than what you're expecting. Mostly the audio takes a huge hit. Some of the controls takes a little while to get use to. Thankfully there's a save feature. It's also among a few handful of Sega releases for the franchise.
