Sorry to bump an old thread, but i'm using drastic and having this exact issue, anybody know how to fix it? Trying to get myself a Growlithe on Platinum. Have tried using PKHeX, PokeGen & PokeSav, same issues on all, either a black screen on using the computer in the Pokemon Center, or the game goes really slowly, or both. The edit itself does work, I do get Growlithe, just the aforementioned issues make it unplayable.
