Beta64

Background
Beta64 is an American YouTube channel that documents pre-release and unused content in video games, mainly Nintendo titles. Currently, as of July 2023, the channel's content is on hiatus.

1st Logo (December 12, 2012-January 18, 2015)
Logo: On a white background, we see a parody of the Nintendo 64 logo, depicting the word "BETA" as the "N" cube shape, and "BETA" replacing "NINTENDO". The "BETA" cube spins, as does the normal N64 logo.

Technique: 2D-looking computer animation.

Music/Sounds: A different track depending on the video topic (e.g. Super Paper Mario uses the game's prologue theme "Today's Story", while Super Mario 64 uses the game's file select theme).

Availability: Appeared on all of the channel's videos from the first episode, Luigi's Mansion, all the way until the Yoshi's Island episode.

2nd Logo (March 2-November 18, 2015)
Logo: This is essentually a parody of the 64DD bios screen, featuring the "BETA" cube rotating as the screen ripples and the logo fades above. The logo drops and then Mario (in his Super Mario 64 appearance) pops out, waving.

Technique: 2D-looking computer animation, similar to the previous logo.

Music/Sounds: The 64DD track, followed by a soundbite of Mario (Charles Martinet) that changes every video.

Availability: This was rather short-lived. It first appeared on the Sonic Adventure episode and last appeared on the Mario Tennis: Ultra Smash review.

3rd Logo (December 24, 2015-May 11, 2018)
Logo: On a white/gray background, we see various models and sprites from various video games being formed up from polygons to what they look like, which then form into different landscapes until they all merge together into the "BETA" square, as "BETA64" appears through a flash of light. The animator's credit appears on the bottom left.

Technique: CGI animation by Nicholas Kaighen.

Music/Sounds: A retro-sounding track.

Availability: First appeared on the LittleBigPlanet episode and last appeared on the Kirby 64: The Crystal Shards episode.

4th Logo (February 3, 2019)
Logo: The video footage rotates away into the white background and a blue dot forms up various images of different used sprites or designs in video games. Then, they all turn into dots as various lines move to the right of the screen. The "BETA64" logo appears on the top, and then an image of Andrew (the person behind the channel) appears in place of the "BETA" cube. His image rotates in different poses i.e. Paper Mario's sprite.

Technique: Simple animation.

Music/Sounds: A modern, techno version of the Super Smash Bros. Melee version of "Fourside", originally from Earthbound.

Availability: Only appeared in the Super Smash Bros. Ultimate episode. It was originally planned to be the intro to the series in the future, but due to poor reception in regard to Andrew's "forced" attempts at humor in the video, it went on unused.

5th Logo (December 20, 2019-December 20, 2021)
Logo: A CGI remake of the second logo, but instead of Mario popping out, a 3D model of Andrew done in Super Mario 64 style pops out of the "BETA" cube.

Technique: CGI animation.

Music/Sounds: Same as before, but this time a different sound effect plays when the cube drops, sometimes with a different sound playing when Andrew pops out.

Availability: First appeared on the Wii Channels, Miis and the Wii Menu episode. It's most recent appearance was on the The 3DS and Nintendo's History with 3D episode. This is due to the series entering hiatus after Andrew confirmed in November 2022 that he was working on his own video game and focusing more on streaming on Twitch.
