Ever since Morimoto published his legendary movie in mid-2003, the players at TASVideos have repeatedly made it faster and faster and even faster! Of course, there doesn't ever seem to be a stop for when it is fastest.
This movie is 0.59 seconds faster than the previous movie. Most of the improvement comes from Bowser's Castle, where the authors didn't have to lose time in order to get a favourable Bowser pattern. For more details, see the run's comments.
You can see this run played on an NES right here.
The encodes feature commentary as soft subtitles.
