Alright, so I have a retail Diamond. I traded in all of my GBA pokemon games in the past, and now I want to play some of them again on my DS with the EZ Flash 1-in-3 flashcart. I mostly want to play the games with such things so I can migrate pokemon from the GBA games to DS Pokemon games. I already have a DS and an R4DS cart, so I'm good with all that. All I really need to know is if I can migrate GBA pokemon to the DS Pokemon games, which I'm sure I can do. I just need to know how, since I'm pretty good with the DS flashcart stuff, and not the GBA. I plan on buying a EZF1-3 cart tonight if I understand it all.
