Alpha Craft
by _FN10_
Alpha Craft is a NeoForge mod for 1.21.1 that reproduces the look and feel of early Minecraft versions, from beta-era ores to the old overworld and nether.
What it does
Players who go back in time can collect early resources and build the nether spire structures the old Pocket Edition used. Alpha Craft also brings in some newer ores such as beta-style iron and a portal crafted from them. Its author expects a nostalgia trip in places and says the mod is faithful to early versions, though a few items and behaviors are not fully implemented. Some structures must be built and then activated, and cobblestone behaves differently because blocks in the old dimensions and alpha variants are special.
Progress runs through a miniboss called Giant. Killing it drops a giant core, which crafts a Nether Reactor Core. Activating that core spawns a nether spire with different items and zombie pigmen. Blasting netherrack can yield old obsidian, and the mod adds ways to move items between the older and newer versions of the same blocks. The mod runs on the server and on each client, so both sides need it.
The mod is released under the MIT License and is not open source. Its only published file is 0.2.0 for 1.21.1, an alpha-channel build from 2025-01-06, and the first release is dated 2025-01-04.

What the author says
In the Alphacraft mod, expect to go on a nostalgia trip, as some of the places in this mod are very faithful to the early versions of Minecraft. You can collect some new ores, like beta, and the old iron ore, then you can use them to craft a portal to the old overworld. Beware, as some things are not the same, as you…
