1. You need someone else to share their challenge key with you before you start your game.These questions are probably well know info around here but,
How do you activate challenge mode at the beginning of your journey?
I know there is some kind of compatibility with BW in terms of story or whatever, how does that work?
2. There are two ways of using Memory Link. You can either do it by using two DS systems (one with B2/W2, one with B/W), or by using Game Sync with B/W to get a code to enter into BW2. In both cases, you set up Memory Link by going into Unova Link from the main menu.
