Take a look here to learn a bit more, the file has the same length as the movie due to further imputs in the next location https://tasvideos.org/UserFiles/Info/639000601605005023
37 frames were saved, which for some unknown reason were lost despite perfect presses before. I am not sure how this happened, the cause is still unknown to me.
This file also has 33 frames saved over the previous WIP file. Thanks to the no waiting the number of frames for manipulation, with getting OK earlier than at the end, allowed to get lucky at the end.

Mario & Luigi Bowser's Inside story is the third game in the series. Fawful is back and he wants to take over the mushroom kingdom. He gives a lucky? shroom to Bowser which gives him the ability to vacuum. Bowser then swallows everyone at the castle. Mario & Luigi must then team-up with Bowser to prevent Fawful from reaching his goal.

Game objectives

  • Emulator: BizHawk 2.11
  • Game version: Japanese (MARIO&LUIGI3_CLJJ01_00.nds)
  • RNG manipulation
  • Genre: RPG

RNG manipulation

A big part of the run is RNG manipulation. The formula is RNG(x) = floor(20.5x)&0x7fff + (x%2)*0x8000. RNG only changes when necessary in battle which means that I have to manipulate before the battle. The initial seed depends of the frame you enter the frame.
In this file, I will discuss the savings and time losses compared to the previous TAS. The frame calculations may be inaccurate by 1-2, but I will try to explain as best I can.

Peach's Castle

I save 27 frames at the first location because Toad arrives at this door faster in the Japanese version, and a few frames on the dialogues.

Bowser

I'm losing 37 frames here, it's possible that there's lag here, the same RNG manipulation frame time and the same attack patterns.
