Since you fuckers seem to be the most knowledgable when it comes to this sort of thing, I have a question to posit.

Theoretically, if one were to play a romhack, like let's say Blaze Black 2, would they be able to transfer the Pokemon they've bred/caught into Oras through pkhex?

I never had the chance to play 5th Gen and I'm pretty bummed about it, but I also don't want it to be for nothing as I enjoy carrying my Pokemon over through the years. I also want the best possible experience, and rom hacks seem to be a great way to go about playing the games.
