    For the intended experience, play with the Golden Days (Base + Alpha) or Classic Alternative (NEON) resource packs, Optifine/Colormatic (for custom color support), moody brightness, and no smooth lighting!

    Looking for Beta-style terrain gen? Take a look at Neo-Beta!

    Modern Alpha -- Generate Alpha terrain in modern Minecraft!

    This terrain generation data pack emulates classic Alpha terrain circa a1.1.2_01, with ore and mob spawns modified accordingly! No granite/andesite/diorite, no lapis lazuli, no Endermen, fancy Oak trees courtesy of Forester, just like the old days!

    Also includes the Modern Alpha Plus data pack, with the same terrain generation, but with most structures, all the new ores, and most modern mobs!


    Alpha-style Generation

    Rolling hills, cool cliffs, classic sand and gravel beaches!

    Try the Nether!

    Visit a pre-Adventure Update Nether! Modern Alpha Plus offers the new 1.16 Nether, if that's more your thing.

    Winter Mode!

    Both Modern Alpha and Modern Alpha Plus offer an additional Winter Mode-based overworld!

    Modern Alpha Plus for a Nearly Complete Experience!

    Modern Alpha Plus offers the same terrain generation and mob spawns as the main data pack, but also includes most structures, including villages, pillager outposts, ruined portals, mineshafts, and strongholds! You also get all the new ores, the new Nether, etc! Play in the standard or Winter Mode dimensions, as well as an "Overworld Plus" dimension that features both as biomes!

    1. Download the .zip file and extract the folders.
    2. (Optional) Edit the overworld.json file as described above with your seed.
    3. (Optional) To use the Winter Mode or Overworld Plus (if using Modern Alpha Plus) overworld, go to Modern Alpha (Plus)/data/minecraft/dimension, rename overworld.json to something else, then winter_mode.json or overworld_plus.json to overworld.json.
    4. In Minecraft, enter the Create a New World screen and select Data Packs.
    5. Drag either Modern Alpha or Modern Alpha Plus into the game window and move it into 'Selected'. The data pack should be ordered above the Default data pack.
    6. Create the world!

    Known Issues:
    • If you have issues with foliage colors being incorrect, please be sure to use the recommended resource packs with Optifine or Colormatic on Fabric.

    NOTE: Custom worlds/dimensions are still experimental and may be unstable and prone to issues.

    Feedback and comments welcome!

    Feel free to work off of this pack but please credit me! If you wish to repackage the data pack in a modpack, please ask first. Please do not redistribute the data pack alone as-is, I would prefer if you just linked back here!

    Um I tried the pack and I works great but when ever I load a new world with the pack it always generates the same seed. Is this intentional or is this a bug of some sort?

    You're going to have to open the pack and change the seed field in the dimension file.

    My favorite oldschool world gen was Alpha 1.0.16_02, but this is close enough. Certainly beats creating a new world in alpha & slowly upgrading it to the latest version with increasing chunk error regeneration.

    Your datapacks are amazing! Can you make a datapack that mimics the 0.0.14a or 0.0.11a generation? It would be cool to see these in bigger world generation. I left a few photos but it would be better if you go to the versions and generate some levels and see yourself(if these versions are not in the official launcher, you can download betacraft launcher)

    Hey man! Amazing job, thanks for keeping this up :D What about Monolyths? Do you think you would be able to add them back to the game? youtu.be/ScJztXBgYB4

    Plus: i am having serious problems removing this data pack. When i remove it world generation start lagging badly, and everything gets generated as stone.

    just to say, this does not happen when i remove the neo beta data pack from skydeck

    Monoliths were a terrain generator quirk. They can't be added through data packs.

    I would expect the game to revert to default terrain gen if you were to remove this, but beyond that, I can't really speak to the effects as vanilla custom world gen is still an experimental feature.

    Is there also a way to make this in Bedrock Edition? I missed those old biomed!
