DSi's do work, just not yet. Omega and Bond are vigorously testing AR codes for it. I am currently their guinea pig since I am the only one with an actual DS and Cart for most of the games. But either way, that big chunky one will work to. But you will need to play the game a bit before you can effectively RNG anywho. If you want some B/W pokes ahead of time though, let me know and I will trade you some. Just check my thread.
