Super Mario 64: OS Edition

Super Mario 64: OS Edition was supposed to be a version of Super Mario 64 pre-packaged with the MariOS 64 system, but was cancelled alongside said operating system. This version of the game was supposed to be an "enchanced" version of the game, with new features that made it stand out with the Nintendo 64 version, particularly an advanced version of the Personalisation A.I. It was also able to use custom-made content made from the programs MariOS 64 contained in order to show them in gameplay.

Along with MariOS 64, it was leaked from an anonymous forum by an anonymous programmer for Nintendo around 2020 that seemed to have a "finished" version of the game (not to be confused with Mario Darkness). It is alleged from the programmer that Super Mario 64: OS Edition was originally just supposed to be a PC port for Super Mario 64, without the OS stuff being in question at that point.

List of Additional/Changed Features
The list of features that were added or changed into the game are vast and will be listed here:


 * The addition of multiplayer via Internet connection, as well as LAN play and direct-dial modem play, allowing the playability of multiple characters such as Mario and Luigi.
 * An advanced version of the personalisation A.I with newer capabilities and being able to connect to the Internet, allowing for it to use content all throughout the web in order to cater towards the player
 * The ability to use custom-made content that can appear in the game via the programs in MariOS 64, and the ability to download other custom content made by other people
 * "Events" in the game that can be triggered by the date, allowing for unique stuff to appear in certain days (the player's birthday, Christmas, Valentine's Day, etc.)
 * The ability to send unique versions of the game to others via E-Mail as a gift, provided if they are using the MariOS 64 operating system.
 * The object limit of the game has been removed entirely
 * Optimization features such as resolution, sound and music audio levels, fps toggling (frames per second), and quality of graphics/models have been added.
 * Cheat codes in the game via typing them in onto one of the options in the game.

Trivia

 * The idea for an "updated" version of Super Mario 64 was later used for Super Mario 64 DS, although it does not contain personalisation features.
 * Coinicdentally, a PC version of Super Mario 64 was developed by fans of the game. However, considering that it has been made from a decompilation of the game's base code, there are no personalisation features for the port.
