On the download play thing on 3DS, I think it lets you connect to DS systems, so maybe you can trade Pokemon from DS to 3DS.Peachy said:What I meant is I don't think a DS cartridge can contact a 3DS cartridge through Wi-Fi. They are 2 separate systems, B/W on DS, and the R/S remakes (assumed) on the 3DS. So, what I'm saying, is if they make remakes... and the games are for the 3DS, I don't think you'll be able to trade B/W stuff since it's on a DS cartridge, while the R/S would be a 3DS cartridge, so that makes trading impossible unless they make this thing on R/S where you can trade it over like with what Diamond/Pearl did to Ruby/Sapphire with the GBA to DS thing, see what I'm saying? If this doesn't make sense, then I don't know how much more I can explain it...
