Oh awesome! Thank you so much!

I don't know if this is an active thread, but I used this tool to expand Pokémon. Initially, it appeared to work well, but the game crashes any time I encounter any of the newly added Pokémon in the grass or in the wild. Does anybody have any idea what may cause that?

This isn't a tool. It is a feature branch that you could apply to a decomp-based project that is no longer being worked on individually as it is now a part of the Pokeemerald-expansion Master and Upcoming branches.

Having clarified that, in order to make sure you're not getting confused with binary hacking, every new species works perfectly fine.
They worked fine when the PE was an individual feature branch, and they work fine even now as a part of the Pokeemerald-expansion's Master and Upcoming branches.
