Oh, I've definitely uploaded worse, as well.
I've picked up a couple of extra strategies. Mostly just getting used to where the enemies spawn, a couple of different tactics for taking down a couple of the bosses a bit faster, etc. It's also easier to control on the NES, so there's a lot less "FUCK YOU COGS OF DEATH!" in the last level, and more "SWISH" as I jump through the narrow openings. I'm still working on my Joker battle plans, though, 'cause I just... can't quite seem to find a method that works for me there.
I've noticed that the majority of the "no-death" or "no-hit" runs on Youtube don't have commentary. I'm assuming this is because they need to concentrate.
I just watched a no-death run that was obviously recorded with an emulator, and while he has pretty much the exact same strategy in all of the same places as I do, there's a couple of parts where he is severely lacking.
Beyond that, though, it would simply be a truncated version of the original run that I already did, where I learned how to beat most of these guys (ie., the two white boxes are SO MUCH EASIER when you're not trying to dodge them all the time and get off one boomerang shot at a time).
I'm going to hold onto it, and if I can't get a recording of a no death run by the end of the weekend, then I'll post it and never play the fucking game again.
