I brought up in that (very old) thread that I'd like to see a more polished version of it, but McBobX pointed out that a run like that wouldn't get accepted due to using a cheat code.
While that's true, the cheat code in this example is different than the Konami code, or debug mode in Sonic or something. It grants you an armor with abilities that you can't otherwise have in the game, which can lead to interesting alternative routes taken in stages and you being able to obtain certain power-ups or items earlier.
In cases like these where the in-game cheat codes provide you a unique experience, can videos be submitted with them for the purpose of entertainment? I'll quote myself from that thread: "We've numerous runs of games here using emulator-specific trickery or of ROM hacks that don't work on real consoles. Why are they here? Entertainment. "
