i can't figure it out
Any DS BUT On 3DS only, you can get the new forms of Thundurus, Tornadus, and Landorus, as well as the new Keldeo(Likely). These are not available to DSi/DS.
The game is also region-locked on the DSi/3DS but not on DS/DS Lite.
Basically, they are both compatible with any type of DS. (Hope This Helps!) :)
Actually, I can answer this for sure. Nintendo Power has said that they will be a DS release. Meaning they will be able to be played on any DS.
