My original post is the same thing. I know it's total run was 5:05. I could care less since this is cool to watch. No cheats are used on either vid, but these speed runs are done with emulators and are perfect because they constantly save at every hard part and reload it when mistakes are made until it's absolutely the fastest it can be.

Is this part of a speed-run?

it says it was a "tool assisted" movie. Alot of these speed runs are done on emulators and those emulators have the ability to "save state" which is saving the exact position of your game, anywhere, then you can "load state" and pick up from where you saved it. So for example, the mario 3 run that was so popular a while ago, was done this way, constantly saving and reloading states to create a "perfect" run.. Not sure about this specific movie, but ALOT of the older console speed runs are done this way, but thats what he meant by "tool assisted" movie. Still very impressive either way. But yeah, it would be much harder if it was all 1 run. These runs are usually done just for the ART of it.

Speed runs of SMB are overrated. Now this was a challenge. Though personally, I'd have better luck with SMB than any one of those adventure games.
