I could even use some emulator on my PC to make those changes, I don't really really care. But the point is, I don't have a GBA, nor a DS, nor any cable, nor any real game, just a 3ds and the XY, and of course, a PC, internet and lots of time to search for it. I found a lot of 'Put the GBA game into your DS', 'Use the cable', 'Use the wireless cable', and so on, a few guys asking about the same question as me, but not so much answers.
The point is, Ive been looking quite a while on internet for it, about how to transfer those Pokémons found on earlier generations, onto the next generations, without the real GBA or DS, and I haven't found so much useful info. For quite a while, I've been trying to complete my Pokédex in XY, a lot of trouble with the legendary ones, and I've got some (hopefully brilliant) idea: I've been thinking about playing all other Pokémon games, starting from FireRed / LeafGreen in GBA, in order to get all legendary ones I could find.
