If you mean your trying to get the mascot legend of the game, then what you do is go to VR and somewhere on the right area of it you should see a Zoroark, follow it. It will bring you to the Old Team Plasma Castle and there you'll find N and have to go to where you battled him in B/W. Once there you have to fight his Zeky//Reshy and after it being defeated then N'll give you the DS/WS. From there you go to Dragonspiral and at the top the stone of your game will start reacting and you can catch Zeky/Reshy. If you're talking about just the main story then I can't help you there (Haven't played on the emu version or the Jap cartridge ver.)
