Once you transfer pokemon to your DS, you can't get them back onto your gameboy... Now I have to decide if I want to dump most of my pokemon from ruby to Diamond....
Yeah, because you transfer from the GBA game to Pal Park and then nothing has been said about getting them back. So I'll probably trade over Pokemon from my old LG game (I saved some by transfering to Colosseum) and Colosseum pokemon which are both in LG right now.
I thought you trade them bacl, but you have to trade the same ones you trade before, and had the same moves as ruby/sapphire.... oh that sucks now... its hard to decide now for my shiny zangoose...
