Survival Islands
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.
Survival Islands
This is a datapack that changes the overworld generation to create islands in an endless ocean. Along with changing the biomes, the terrain has been slightly altered as well, always being flatter near coasts for the more traditional survival island experience, as well as making oceans ~1.5x deeper. It is a very small modification and should be compatible with most other biome and terrain mods.
I highly recommend using Jacobjo's Datapack Map to scout the seed if you are wanting to find the perfect spawn island.
