Mario Darkness

Mario Darkness is a website made in 2004, and shut down in 2007. It was made by user DarkAdmin56. The website was a forum about ROM hacking Super Mario 64, and for hacking the unreleased MariOS 64. It is unknown how they managed to create ROM hacks so early, but it might be due to the MariOS level editor, and how easy it is to modify. The website shut down in 2007 due to a DMCA by Nintendo, however it seems to be somewhat active up to this day.

Website
The website consists of categories, containing multiple boards. These boards are used to talk about miscellaneous things, such as video games, or Super Mario 64. There are also boards for ROM hacking, and for MariOS. The users seem to talk about having encountered anomalies, mainly on the Super Mario 64 board, although the admin is skeptical of it. The other important boards are the MariOS boards. Mario Darkness's admin, DarkAdmin56 was developing a hack of MariOS that was supposed to have a better level editor. This hack was called DarkOS, although it has not been released, and will likely not be.

Darkness Hacker
On the website, on the ROM Hacks board there is a thread that links to a dead MediaFire page. Apparently, this was a Super Mario 64 ROM hacking tool called "Darkness Hacker." It is unknown what the content of Darkness Hacker were, but it can be theorized that it was something similar to the ROM Manager and Quad64 we have today. All MediaFire links on the forum seem to be dead.

Theorising
Mario Darkness does not seem to be an anomaly, but it has a correlation with other anomalies, and mainly MariOS 64. It is unknown whether or not the users saw is true, but it can be linked to the Personalisation A.I. The so-called "DarkOS" has not been released and will probably never be, although it is possible to try and get in contact with DarkAdmin56, wherever he is now. Darkness Hacker still has no working download up online, but it is very clear it was similar to Quad64 or ROM Manager, but in a much more primitive form. The forum seems to still be accessible, despite the announcement of it shutting down in 2007, possibly due to relations with the MariOS 64 leak. All of the download links used by the users of the forum seem to not be working, as they could of been taken down by Nintendo themselves.
