In my opinion,
movies where you push Up+Down aren't possible on a console either (neither are savestates but that's not the point here). Okay, maybe you can dismantle the controller to push both at once. Then let's assume it's possible to dismantle the cartridge while I'm playing and wipe the SRAM or something.
Actually, I think what disqualifies this method is that it's ONLY possible if you use a movie file. Isn't that bizarre? It's possible if you record a movie of it... but it's impossible if you don't record! It sounds like something out of Quantum Physics, though it's actually some obscure movie-recording programming bug in
both emulators which no one will bother investigating since it's harmless. Even if you somehow wiped clean the SRAM while playing on a console, you'd never be able to do this because you can't record movies! (actually, you'd get the bug where you respawn on rainy Zebes, but that isn't as impressive) If you really wanted to, you could connect some machine to the controller port so it can perform all the other speedruns on this site with perfect reflexes, but you could never do this movie trick on a console. So that's the real reason it shouldn't be published.
Still, I think it's quite funny to watch anyway.
