[1.16.2] Adding a custom world type with custom biomes

[OverInfrared]

I have custom biomes that I have created and added to the vanilla world, but I don't want to add them to the default overworld. I want to make my own overworld with its own biomes (i.e. biomes o plenty) so you only get mine. But, there are no resources for the creation of custom world types for 1.16.2 and 1.15.x. Specifically I looked at biomes o plenty's code and seen that they use a class called BiomeGeneratorTypeScreens, this works to an extent but to get it fully working biomes o plenty uses a ton of custom classes to overwrite the whole of vanilla generation when I only want my custom biomes on the current system.

First, update to the latest minor. Second, this just sounds like a datapack that replaces the overworld dimension. There is no real need to have anything declared in code here. If they want your datapack, they add it. If not, they don't have it.

I would also like to add modded ores and other features to the world not just vanilla.

If you create the blocks and features, then you would need a mod. However, all of that would still be handled by the datapack itself. If you wanted those ores and features to spawn in a vanilla biome, then you would use BiomeLoadingEvent after you update to the latest minor.
