What a great idea!
and what a great first submission to Newgrounds, too. I must commend you on the idea and also the execution. Your author's comments alone are funny, and watching the headline and article change from the original to a new 2003 one was great.
My one complaint, and the reason I lowered the graphics score just a tad, is that Little Big Mac, while indeed larger than his original self, clashes badly with the spritey goodness of all the NES graphics. He looks like he popped from a newspaper comic strip or something right into the video game. His smooth lines and coloration don't match up well with Mike Tyson, the ref, his trainer, or the backgrounds.
That said, it's all good nonetheless. Great job!
