You can with a normal link cable
You can trade pokémon by using a link cable between your GBA sp / GBA.
It doesn't work with a wireless adaptor.AnswerUnfortunately, Pokemon Sapphire is not compatible with the wireless adaptor which was released with Pokemon LeafGreen. It can only trade to or receive from LeafGreen via a link cable, which is only possible through the use of two Game Boy Advanced (or SP) systems. If you try to initiate trade through two DS systems, you will find that a link cable cannot be used and that the wireless connection in LeafGreen cannot be established, even though it is a wireless compatible game (the systems are different, so LeafGreen will not link with the DS' wireless communications).
