How to build multiple regions in pokeemerald?

[PokemonXO]

Hello! I am looking for any tutorials or open source projects that can integrate Fire Red's unique multi-region map feature.

There are quite a number of delimnas you can run into when trying to port Fire Red's code into Emerald, including warnings and error messages that will drive you insane (personal experience).

Hopefully, I can find someone here that can guide me to the right place to learn or port this feature properly. I think it has been done before, but I did a thorough search on google and github and didn't find anything. So I'm guessing all the projects that have done this successfully are either: Completed and closed source, uncompleted and closed source, or simply closed source.

It would be really nice to know how to implement this. I am using porymap's region map editor, and adding a couple regions alongside hoenn.

Invites to private projects to skim over how it was done are welcome too!

Thanks.

Hi,
I'm also looking for a way to add multiples regions.
I kinda could do something (changing the hoenn map was a first step - but it crash...) then I stop trying for now because I doesn't seem to work.
If needed I'll attached what I've done.
It's not working but maybe it'll help you?
I'll start working on this project soon
