Super Mario Bros. for PC

I have a copy of something called "Super Mario All-Stars & World" that contains all the SMB games plus the Lost Levels and World, obviously. What surprises me is that it's for PC, were there any Super Mario Bros. games released for PC? I don't remember seeing such a thing. But it exists. 

Just mentioning it for people that are interested in such a thing, don't really wanna post a link here, so if interested just PM me. It has some funny resolution, funky controls(arrow keys for movement, the "a" and "z" keys replace the "A" and "B" buttons) but for Mario fans, it's just perfect. Tho it doesn't have the retro graphics(REMASTERED JUICINESS FTW) that applied (I believe so) for the SNES version of Super Mario All-Stars. Don't really know what I'm talking about, but it's sick to have this on PC(can't stress this enough).
