This is a great topic I found accidentally while searching for something else. While I love my 7800, I can't see how anyone can seriously debate this. A better question would be "Would the original SMB be possible on the 7800?" Even with that question, I still say no. The fast scrolling and fast-paced action, pastel colors, and music don't seem possible. However, if someone makes a homebrew and proves me wrong, I'd be happy to admit it.
