I gotta hand it to DahrkDaiz; Mario Adventure is one of THE best 2D side-scrolling platforming I've ever played. You could say that this game is a hack of Super Mario Bros. 3, but I, like so many others, believe it's so much more than that. I'd go more in depth, but I think the good people at Vintage Computing could do that much better than I could: http://www.vintagecomputing.com/index.php/archives/63 . I also took the time to create a page with the instruction manual: http://www.freewebs.com/marioadventuremanual/
