It's faster than Pom's movie but if your first thoughts was this movie aimed to obsolete POM's movie, then you are wrong. Yes, it's faster but another ROM version is used.

We've heard many rumors about Minus world -1 could be beaten and that Worlds -2, -3 and -4 exist. But in NES and Unisystem versions, the level is repeating when you enter the pipe at "end" of level. We've seen hoaxes like that but nothing proved us it was true. Except - 4, -2 and -3 really exist. After you beat -3, the game has been beaten once. Some people are claiming that you must deliver the princess to beat the game. I am saying, I saved 2 princesses. In any case, I think I should compare it to some Zelda glitched runs where some goals hasn't been achieved.

Note that when you beat the game, level select and 2nd quest modes are activated. So, I purposely stop the movie later to press B to return to title screen to let people verify by themself.

Bisqwit: … as a concept demo. This will not obsolete Pom's movie, not the least because it's a different game with different rules. (The differences in the games (NES SMB1, FDS SMB1) are completely unintentional and driven by the platform change, but striking in this particular movie.)
Bisqwit: Processing.
