I'm in the process of migrating my Pokemon from White 2 to Gen 6 (Y / Pokemon Bank) via Poke Transporter. However, some of them wouldn't go through. I've attached the ones that got rejected, (although I had to change the .pk5 to .pkm because .pk5 doesn't seem to be accepted.)
The event Pokemon I used legit Wondercard data from the Pokedit Event Pokemon database, and the others I pretty much caught legitimately. The only modifications I made were to make them shiny. I gave them no custom stats or moves. There might be some weirdness with with the gen 1 & 2 ones since moving them to gen 3 obviously required some alternative steps. (You know the process.)
I guess PokeCheck is gone, and I don't know any other way to check what's wrong with these Pokemon. Maybe someone can help me with this?
