how to beat Pokemon emerald
You can trade Pokemon from another Diamond, Pearl, or Platinum version before you beat the Elite Four, but you cannot import Pokemon from any previous versions. However, once you beat the Elite Four Pal Park will open and allow you to import six Pokemon at a time from any Ruby, Sapphire, Emerald, FireRed, or LeafGreen game that is inserted into your DS at the same time. Be warned, these Pokemon disappear from the game you import them from and cannot be returned in any way.
