How do I install 1024?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does 1024 work with?

The listing gives Minecraft 1.21, 1.21.1, 1.21.2, among others. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

A house underneath the minecraft world, with text saying "1024" shown above. This datapack allows you to build with even more room than ever before! Build height in the overworld is extended from the vanilla 384 (-64 to 320) to 1024 (-512 to 512). Not only this, but it also replaces bedrock with reinforced deepslate, allowing you to build underground!

SOME PACKS I RECOMMEND TO GO WITH THIS:

Pickaxe Effective Reinforced Deepslate [PurpurPack] - Makes it a tad less miserable to get beneath the deepslate

Silk Touch Reinforced Deepslate [PurpurPack] - Lets you patch holes in the deepslate after you break them

Questions I know you'll ask:

Why no Nether and End? man idk. i'll probably add them in another update? Why not more blocks? e.g. 2048? i would consider 2048, but I made this almost exclusively for a server i'm hosting, and said server is REALLY slow, more blocks = more stress, more stress = slower server :( Why make it go under bedrock? to be honest, i think being able to build under bedrock provides a lot of really fun build opportunities!! like, wanna make skyblock? boom. parkour with an additional amount of fear to it? boom. the opportunities are endless.... Why replace bedrock with reinforced deepslate? i mean... you're meant to go down there for building reasons now, why would i keep it as impossible to break? i chose reinforced deepslate since i felt it was a good match, really hard block and still deepslate related. i was originally gonna try obsidian, but that felt really boring.
