Biome Replacer (Neoforge)
A quick way to get rid of a biome. Useful for tweaking datapack-based generators (like Terralith) that don't have a convenient configuration
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.
