I can't believe it took this long to add BD/SP support.

Actually, I've heard that the reason it took so long for BDSP is because of something to do with how ILCA coded the games.

If memory serves, it's basically like this: BDSP's Pokemon data is set up differently than Sword and Shield and all that. I think it might've had something to do with being made in Unity? I don't remember full specifics. But BDSP was basically incompatible with... everything else. So my guess is the reason it took so long was because they needed to find a way to convert it properly?

As for Arceus, I haven't heard of it sharing the same problem, so I'm just assuming they wanted to bundle it all together in one update instead of giving Arceus first, having to do maintenance, and then releasing BDSP compatibility and having to do MORE maintenance.

Unfortunately I don't have a source on this at this particular moment but I'm gonna try to find one. I know there were a bunch of twitter posts talking about the specifics. Not that Twitter is really considered a reliable source.

All that said, don't think I'm defending this: It IS ridiculous it took this long, and if I'm right about the reason for it, well, that shouldn't have BEEN a thing in the first place. But hey, better late than never... I guess.

All that to say, I'm expecting (read: hoping and praying to god) that SV compatibility won't take nearly as long, since Gamefreak are at the helm of this game and will probably just do things how they usually do. In terms of coding and everything else.

EDIT: I found an article talking about it. Not gonna give a tl;dr because quite frankly I don't understand most of the jargon they use in the article, but give it a read and it should provide some answers: https://comicbook.com/gaming/news/pokemon-brilliant-diamond-shining-pearl-pokemon-home-issues/
