For what it is, it's actually technically sound. It's just a shame that "what it is" is "completely unacceptable for publication due to using Game Genie codes". TASes like these are much better suited for
the game's thread, where you can show them off without worry of being judged against the site rules, or alternately April Fool's Day, which is just a big opportunity for people to mess around with nonstandard runs, once again without any worry of being judged as a legit submission.
It's clear you have the ability to optimize and think outside the box, and I'd love to see that applied to an acceptable submission, though... Perhaps not SMB1. I feel like SMB1 is one of the only games, if not THE only game, on the site that has reached theoretical perfection. You'd have to discover something groundbreaking or do something absolutely incredible to get an SMB1 TAS published these days. I can't stop you from trying, of course, and I wouldn't want to do that anyway, but just keep in mind that if you intend to keep submitting, you're going to have a hard, if not impossible time if you stick to SMB1.
Whatever you do, though, stick around the community and keep at it!
