Who else? I got it from the Salvation Army like a decade ago and have never played it, because I don't have a 5.25" drive, like most humans.

I was not aware of Mega Man DOS...yikes.

Those old Mega Man covers always bring a smile to my face. Just look at it!

Hey man, don't pass judgment if you haven't tried it! I mean, have you seen Dynaman's adorable, nervous smile??

Wow, I've never heard of this. That's awesome. Did they have any connection with Capcom, or is this essentially a fanmade game?

I have never seen this version of mega man before and I must play it to know.

Oh wow, this is something alright! They should play this on UPF!

I remember playing this as a kid. For a non-Nintendo kid, it was the only Megaman I knew for the longest time. PC Gamer did a story on this anomaly a few years ago: Linkie

I'm not going to link it directly since I am not sure of the legalities, but for those inclined to suffer through it archive.org has it running in-browser using DOSbox.

The story of it existing is great

Basically some guy at Capcom was just making it on his spare time and when he left he asked if it could be just published and released and for some reason Capcom just said sure why not
