Editing late gen Pokémon in early generation files.

[caioiac]

So I've been searching for a solution to this problem and I can't find it, I don't even know if there is one.

I'm playing Radical Red GBA rom hack, which has pokémon up to gen 9. But when I load my save file to PKHeX, the file is detected as a 3 gen file, and I can't acess 9 gen pokémon available in the hack ROM.

I don't know if this is a really dumb problem, but I can't find a solution for it.

PKHeX does not support ROM hacks. How would PKHeX even support ROM hacks, those that make arbitrary changes to add in whatever the hack maker feels like?
