Jefftastic's Documentation

In a similar vein to Greenio's Lost Tapes, Youtuber jefftastic has created a series of Super Mario 64 videos based around documenting and demonstrating phenomena in video form. Unlike Greenio's tapes which are presented as found footage, jefftastic's videos are more of a present-day documentation. All of jefftastic's videos on the matter have been cataloged in a playlist called Super Mario 64 documentation.

Mario Update
Unlike the other videos, this video is recorded off screen. Jefftastic narrates the video, explaining how his copy of Super Mario 64 is now refusing to boot up on his Nintendo 64. He shows this, trying to power on his Nintendo 64 with Super Mario 64 inserted, to no avail. He then tries with another game, where it does work. Jefftastic explains that he'll be getting a new copy of Super Mario 64 and continuing to document any anomalies that he finds.

Theorising
Some of these anomalies might only be present in the Romanian release of Super Mario 64, as Jefftastic is from Romania.
