Apparently, a new track in Pokemon Dash can be unlocked if Pokemon Emerald's put inside the GBA slot on the DS.
Since the DS and GBA can't communicate with each other through cables (or the wireless adapter), I sincerely hope Pokemon Diamond and Pokemon Pearl are compatible with the Advance Generation Pokemon series.
