I do have two. You can't with the same system, because Poketransfer requires another DS to use download play and the game in the system to transfer to B/W, while it's still turned on and transferring the download data.
Just so I know...do you have to have two systems? Or can you transfer between games on one system? I'm already presuming I'll be going to Pearl and Platinum to hunt all the Sinnoh creatures and then putting everything (including SoulSilver) on the older DS to transfer to Black someday, but if it can be done same system, I can just plop Pearl onto the older DS and do both Platinum and SoulSilver importing all with one 3DS.
Oh, nutty. I know exactly where that person left off: by National Park. That's where Scyther is in the Bug-Catching Contest (Lv.13-14 I think), and meanwhile Ditto (Lv.10) is back on Route 33 after the forest heading north from Azalea Town.
Glad you got your Ditto...but I didn't think you could transfer out until you beat the game? Did you trade to a finished game on another cart.?
