Both this program and Dr. Mario 64 Password Generator/Decoder Tool were written using the original source code of the game that leaked in July 2020 as reference.

The original implementation of the password generation algorithm inside the source code of the game can be found at bbgames.7z\bbgames.tar\d1\routefree\bbgames\depot\dm64\src\passwd.c, for some reason the password decoding algorithm is absent but it can be easily obtained by inverting the generation one.
