The difficulty in finding the file stemmed from how Minecraft handled files in 2010. The game did not automatically save separate instances of older versions; it simply overwrote the minecraft.jar file in the user's directory whenever an update occurred. To find the "Exclusive" build, archivists needed to locate a hard drive belonging to a player who had downloaded that specific hotfix in December 2010 and had never updated their game or formatted their computer since.
Alpha 1.2.6 was more than just an update; it was a turning point. Released in December 2010, it served as the bridge between the experimental chaos of the early days and the more structured Beta phase.
There is no official version of Minecraft called "Alpha 1.2.601" or "12601." The version history jumps from Alpha 1.2.6 directly to Beta 1.0. However, Alpha 1.2.6 is historically one of the most famous versions because it introduced "The Halloween Update."

Just keep an eye on the horizon. You never know who—or what—might be watching from the fog.
Perhaps the most enduring feature added in this update was The Nether. As a hell-like dimension accessible only by building an obsidian portal and lighting it with a flint and steel, The Nether offered a perilous new realm for players to explore. It contained dangerous new mobs like the flying Ghast and the neutral Zombie Pigman. The Nether also served a practical purpose; by traveling one block in The Nether, you would travel eight blocks in the real world, allowing for incredibly fast transportation systems.

Finding a lost version requires digging through ancient hard drives, looking through old .minecraft folders of players who haven't booted up their old 2010 laptops in a decade. The discovery of rare builds like Alpha 126_01 proves that pieces of gaming history can easily slip through the cracks without active preservation efforts. When a copy was finally verified via its unique MD5 hash, it filled a massive blank space in the evolutionary timeline of Minecraft's source code. Why It Matters Today
