Here's an excellent hack that may also be a nice fit for the spooky season, though it's plenty enjoyable anytime as well!
In Mario 64 B3313, you can explore the plexus -- an oddly dream-like, sprawling "alternate universe" maze of Peach's Castle, full of mixtures of beta content, rumors, oddities, dreams of SM64 made manifest, fan-made lore, and strange characters/events, along with tons of different twists on levels and locations from Super Mario 64 or even other familiar things from across the series. There are parts which one might find frightening, along with others that are cute, bewildering, or even funny -- and there's also plenty of interesting twists on existing musical tracks to go along with it, or even a couple of unique pieces for the hack!
It evokes vibes of strange, exploratory games such as Yume Nikki, though with plenty a twist to call its own. It is even able to read the real-time clock, if the cartridge or emulator supports it, and modify levels and music accordingly in some cases. Some things throughout the game may appear only in the daytime or at night. It is truly something to be experienced.
Also of note is that Mario and Luigi's capabilities are limited from the start -- for instance, when starting a file, Mario and Luigi's long jump is disabled, and their side flip is severely reduced in height. Collecting red stars throughout the plexus is the key to unlocking more moves and capabilities that they are otherwise missing. This explains why I am unable to long jump throughout the video as well.
In the event that you cannot experience this yourself, this video will show a cursory glance at the game -- it is so sprawling and gigantic that even two whole hours may not be enough to account for even 5% of the game's scope.
Please do look out for other videos showcasing this hack if it interests you. One of its versions is additionally compatible with the Nintendo 64 console if played on a flash cart, and should give a suitably classic-feeling experience -- especially if played on a CRT screen, and there are plenty of different playthroughs to watch and see people's impressions of!
