以下説明文
This is a tool-assisted speedrun. For more information, see https://tasvideos.org/7167M
TAS originally published on 2026-06-01

The -1 stage is completely different. In the NES and Unisystem versions, the -1 stage repeats infinitely and cannot be completed, but in FDS, it can be completed, and then come -2 and -3.

The -3 stage in FDS is a castle level, and completing it ends the game, even though it says "princess is in another castle". The princess is not seen in the ending, but she is sighted twice in the -1 stage, as shown in this movie.

This time, the authors aimed at ending the game by executing an arbitrary code rather than defeating Bowser, despite the run being slower than the regular run ( https://tasvideos.org/1715M ). It requires going into minus world twice, first time with Mario (trigger second quest) and second time with Luigi.
