rd-160052 (0h 52min, may 16, 2009 y – 13h 47min, may 16, 2009 y)

Description:

rd-160052 is a pre-Classic version made on May 15, 2009, at 22:52 UTC. It is available in the launcher. The copy in the launcher is recompiled from source code, with dates edited to March 2009, making it technically not original. Additionally, it appears to be tampered with further in order to make the game run in fullscreen by default.

Trivia:

-The name of the game is changed from "Minecraft: Order of the Stone" to simply just "Minecraft".

-The "rd" before the version number stands for RubyDung, a game Notch was working on before Minecraft, whose codebase was later reused for Minecraft.

-When taking a screenshot with PrintScreen, it will take a screenshot of the frame that the program first showed on the screen. Each time the player runs or alt-tabs into the program, it updates that image in memory. When the player hits print screen, it doesn't take what's shown on the player's screen, but for some reason pulls it from that memory.
When alt-tabbing the GUI disappears (Linux).
Rendering glitches occur every so often over time, likely due to game ticks corruption.
