Stlayer.info

stlayer.info was a bizarre website on the internet that displays "cursed imagery" from or relating to Super Mario 64. Going onto a nonexistent subpage would cause a 404 error with an inverted Wario face simply stating "Leave." However, the site has since gone down and no longer exists. An archive of the site exists on the wayback machine.

Audio
Sometimes on the stlayer.info website, an audio track will play in the background. There is a total of 12 audio tracks that the site has, all of which either being disturbing sounds or distorted versions of the Super Mario 64 soundtrack. Most of the music found on stlayer.info can be found on a Youtube video called 1995/07/29 Build INCOMPLETE SOUNDTRACK.

Trivia

 * As seen on the incomplete soundtrack on Youtube, the music refers to a supposed bad ending. The only other known instance of a bad ending in Super Mario 64 is in Greenio's Lost Tapes, specifically in the video 05.30.97.
