Video 1:
Historical inaccuracies - HiDPI display is being used (despite them being unicorns back in 2010-11 since 4K wasn't even a (broad) thing.), modern logo for WinRAR has been blurred out, along side the icon for a generic (non Oracle (or Sun) build) JDK.
This video shows off R4 and a data reset bug within it.
Video 2:
Historical inaccuracies - Bandicam watermark is of latest versions, where as earlier versions had a different one (investigate if bandicam was a thing back in 2010-11).
Shows off _13 Lilypad and a hidden feature within it that unveils a hidden world
Video 3:
Shows off a player in UNR.PREVIEW2 uncovering a creepy easter egg
Video 4:
Historical inaccuracies - 60FPS I guess?
A Michael P parody in R4... I don't have anything else to say
Video 5:
Shows off a player in R4 discovering an unfinished area in the hub with a bunch of recruiter players in the middle of nowhere.
Video 6:
Guide on how to bypass the bans. Later shows off version _18#. Folder is located in [userpath]\AppData\Local\3emj\Minecraft, folder structure contains DX9 related files and the file structure is like this

auth (contains act.id)
gameroot (i assume this is what would normally be .minecraft)
html_cache (cached pages)
jre (bundled java dir)
resources (sound files)
rt_libs (libraries???)
saves (world files)

Video 7:
A group of players showing off their builds and how to build. Version is assumed to be Cypress. Seems to look like AltMojang (or whatever 3emj means) has taken over Minecraft development, since their version seems to be considered the main version since some time in 2010.
Video 8:
Historical inaccuracies - recorded with a modern smartphone
A recruiter/easter egg world player in Cypress stalking the same players from video 7.

Theories:
THEY ARE IN A PARAREL UNIVERSE!!!

Ok, never mind. A lot of videos show dates from 2011...

[forkiesassds]

About the file I should've posted a HEX dump as well. welp... Since that also contains info like player ID which is a 32bit integer (have fun when 2b+ people make an account...)
Player from video 6 has player ID of 2368781344. Guide shows that they are changing their player ID to the one of dev2's which explains why the description of "Sunrise" mentions someone has impersonated dev2.

[forkiesassds]

In November 2011 R4 was latest version, in December 2011 Cypress was the latest, and in development was _18#

[RedstoneWizard08]

I updated everything with (hopefully) correct JSON conversions, and broken stuff like was shown in the right side of the hex editor

In video 6 the login error is caused by the persistent low and high IDs not being changed, also it doesn't make sense that the high bytes are labeled as low bytes and the low bytes labeled as high bytes.

The real mystery is what does 3emj stand for?

The real mystery is what does 3emj stand for?

Hmmm... Googling doesn't help... I wonder if it's referenced anywhere else. I think it's the name of the company that is making the alpha branch (or the Mojang subsidiary possibly)?
