Super Mario Bros. Speedrun in

I found a way to save a small amount of time in nearly every level of the game! It made getting a low 4:54, which should have never been possible, possible! Here's how I did it:
I cheated and hacked the rom lol april fools sorry it's kinda late by the time it's getting uploaded to youtube.

@@Kosmicd12 My time zone is CDT and from my experience the Upload Date does indeed use KZbin's time zone (PDT), regardless of what the uploader's time zone is.

I think the same thing happened again when I uploaded a video around 1:45 AM my time. Whenever I want to upload my videos on a specific date, I always ensure to upload it no earlier than 2:00 AM (because CDT is two hours ahead of PDT).

[@charlesidiot4534]

This romhack is great for several reasons. 1, because the TAS can finally save the frame rule in 1-1, which is the most infamous frame rule ever in Super Mario Bros. Tool-assisted speedrun. 2, the frame rules in 8-1 and 8-2 can be saved somehow easier. 3, because more pizza-eating and coke-drinking video about speedrunning can be created with the help offered by this hack.

[@periwinkle.]

Saw this live lol. GTAce's full FPG video primed me into thinking that you were going to use that trick to get the 4:54, so I hadn't even considered the possibility that the ROM was modified in some other way. (I was looking out for the mid-air jumps, lol. That's also why I thought that "I don't actually know what I need" at the beginning of the video meant "If I do full FPG, I don't know what other tricks I need to do to get 4:54", and that the whole time, you were just doing warm-up/de-rust runs before the "real" attempt where you'd do full FPG in 1-1 and then proceed to get 4:54. Guess I got April Fooled despite already knowing that it was all an April Fools joke :P )
