DatapacksJava
1:1 Nether
Java data pack listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
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.
This datapack makes the nether coordinates 1:1 with the overworld. Encourage using the overworld to travel! It overrides the default the_nether dimension with one that is exactly the same, but with the coordinates scaled 1:1 with the overworld.
I haven't tested it with any other datapacks. I suspect it works on versions earlier than this one, but I haven't tested.
