Super Mario 64 Beta Archive

Super Mario 64 Beta Archive is a YouTube channel that claims to be an archival of unseen beta footage relating to Super Mario 64. The channel features footage of the game in development, as well as unused music tracks and other beta content.

Content
Videos on the Beta Archive channel usually show off beta or unusual discoveries relating to Super Mario 64. None of these discoveries depict the anomalies many channels usually focus on, and instead hone in on original content. For instance, one of these videos shows off an anti-piracy screen for the game. The video calls this screen "rare" as it doesn't seem to exist in the circulated release, although others have stumbled across it.

Music
There are three music tracks uploaded onto the channel, each appearing to be early versions of existing themes. The first two videos claim that the music came from a developer's personal cassette song archive. Although the third track, Early Castle Theme, has no description.

Render Showcase
The video Render Showcase is about showing off old and unseen renders relating to Super Mario 64. These renders were presumably intended to be used in promotional material. The renders seen are as follows:


 * A poster which features Mario, striking the same pose as Sonic the Hedgehog in promotional artwork for Sonic Adventure. The bottom half of the poster reads "Yeah, we've got it too." while boasting about the Nintendo 64's library of games, accompanied with screenshots of Super Mario 64, Banjo-Kazooie, The Legend of Zelda: Ocarina of Time and Mario Kart 64.
 * A render of Mario's head on a blue and white gradient background. Judging by its low quality and nature, it appears to be a test render, or a render intended for a Mario icon.
 * Another test render, this time of Metal Mario. This render was likely to test Metal Mario's reflective texturing, as he's put into an environment with a bright blue sky and brownish yellow floor.
 * The render of Mario and the unused enemy Motos, which used in the channel's banner. This render went unused because Motos was scrapped from Super Mario 64.
 * A render of Mario walking from a white and blue checkered floor to what appears to be a red carpet. The background is blurry and appears painted, likely just being a backdrop. What this render is intended to represent is unknown.
 * A render of Mario on the tip of a tree. These trees bare resemblence to the beta trees found within the July 25th 2020 leak.
 * A render of Mario on a flying carpet, likely to represent Rainbow Ride. Interestingly, this render was reused on an image circulated on some Discord servers hailing from a presumably lost event where six Mario statues could be found around America.
 * The next render stops the background music and fades in from the darkness. What this render depicts is unknown, but many have related it to Bowser; more specifically, this render looks similar to Baby Bowser in Super Mario World 2: Yoshi's Island.
 * A render of Mario on what appears to be the bridge into the castle.
 * A render of Mario sitting atop the Nintendo 64 logo while looking at a cartridge. This render is used in the rare anti-piracy screen.
 * What appears to be an early version of Super Mario 64's box art. Here, Mario is flying atop a basic sky and doesn't have the Wing Cap.
 * A render of Mario in front of a background reading "SUPER MARIO ULTRA 64" for multiple lines. This render is used in the channel's profile picture.
 * A render of Mario on a dark blue background pulling a peace sign.
 * A test render of Mario in a binding pose.

Removed Video
The video 1995/07/29 Build Rejected Commercial was taken down off the Super Mario 64 Beta Archive channel, but can still be viewed with reuploads. The video features gameplay of an earlier build of the game featuring the music that Planet Bobstar ripped from the 1995/07/29 build of the game. When Mario looks up at the castle, the footage corrupts and turns greyscale as the music stutters, before cutting out and ending there.

As disclosed on the community tab, the video was taken down due to the footage supposedly being altered before being sent to the owner of the account. In what way it was altered is still unknown.

Trivia

 * The creator of the Super Mario 64 Beta Archive account is unknown. They imply themselves to be a Nintendo employee in the video description for 1995 Radio Ad, but the true identity of the creator of the account is still a mystery.
 * They sign their posts on the community tab with "EB".
 * In the Wing Cap test video, he was referred to as "Eric". Someone else was also mentioned in the video too, 3 people in fact.
