The title says it all but basically what's going on is that I played through Fire Red and sent my Pokemon through to HG then White and later Black 2 (for PWT). In the end when I tried to transfer them over to Y, it wouldn't work. I haven't tampered with them at all but I do have access to Pokegen and a Flashcart. I've been noticing that the OT always changes to Abrah(weird character)m instead of Abraham.
Any help would be appreciated. Here's one of the PKM files: https://www.mediafire.com/?kh099zt0mtgc0gf
