Emulator: FCE Ultra.
Takes no hits.
This is a homebrew game which you can find at
http://bobrost.com/nes/games.php (it's the 2nd game on the list, and the only one that's really worth it)
The character is a ninja penguin with an attitude (see the "box art" in the same web page), and a double-jump ability. How could you resist that?
The game itself has only one stage, yet shows off a very capable engine. Of course, I don't expect this movie to ever be published, but I still wanted to share this speed run with anybody who happen to know this game. Anyway, it's that day of the year, which hopefully is reason enough to forgive this submission :P
Yes, I was aware of your submission (SMB speed-walk), which I found interesting and funny. Again, I never expected this movie to be published, nor I wanted to, actually. Anyway, yes, it's 6 re-records, but it's actually the third attempt (I beat my own time twice). Also, it's a very short game (only one level), notice how the movie is only 47 seconds long.
By the way, when I said "I hope you forgive this", I was just referring to not being banned, that's all. :P
