If you want to use the best version for speedrunning, use the other guide. If you just want the rando code and that's it, use these.

The link to Pikmin Randomizer is here: https://github.com/Minty-Meeo/Pikmin-1-Randomizer/tree/master

There are 2 available versions; V1: Enemy, boss, and plant randomization. V2: Like version 1 but with better logic and ship part randomization.
