Introduction

https://i.ibb.co/L5nnqys/fast-img.png

This movie builds on top of the recently published Superfast Mario Bros. · warps in 01:09.070 by Denial140, negative_seven, chatterbox. I (eien86) didn't quite pay attention to it while it was being processed because I was working on the Prince of Persia TAS. Once I noticed this romhack, I couldn't help but give it a go. What a piece of fun it was.

Thanks to Denial140 for finding 11 more frames, mainly with the wrong warp in 8-4c. Also to negative seven and chatterbox for their work in the previous movie.

A +- 2 frames are lost/won on emulator differences. We argue that any obsoleting submissions need to be done with Bizhawk to avoid bad CPU/PPU timing and lag detection emulation to distort the movie length.

New Tricks

Fake Vine

For some reason, it is possible to fool the game into believing there's a vine in the middle of the level by pressing L+R at a precise moment, with the effect of having Mario shoot up to the right, saving a bunch of frames.

New Wrong Warp

In 8-4d it is faster to take the wrong warp (exactly as the in the original SMB any%)

General Optimizations

Better execution all over the place, especially 1-2
