I am writing a mod that adds a world preset, and it looks like you are the only person who has figured that out for 1.19.3+.

Respro seems like a key part of what is needed, and you have a heavily changed version of it inside this repo. Please release this so I can use it, or atleast PR your changes to the source repo.

Thanks

It's not yet ready to be used, but I've made the repo for it https://github.com/null2264/Respro. The build failed for some reason, but it should be an easy fix (hopefully).
