for a gba you need a madcatz game link and hook it up to another game boy and trad poke'mon with them
do u mean Pokemon blue or do you mean SAPPHIRE You trade to SAPPHIRE the normal way but u cant trade to blue
if you mean trade them back you can't because they are already on your game unfortunately Hope this helps
No you cannot trade from Sapphire to Platinum. The closest thing that you can do to that is migrate from Sapphire to Platinum.
You can trade with another sapphire, ruby, emerald, firered, leafgreen, Pokemon colosseum, Pokemon xd gale of darkness and Pokemon box ruby and sapphire.
i dont think you can trade from sapphire.
You have get Pokemon ruby and then get it and trade it to Pokemon sapphire. hope i helped!!!
No, you can only migrate Pokemon from sapphire to pearl
no
No

i am almost certain that you cant trade as when Pokemon sapphire was made, Pokemon like bulbasaur werent invented. Sorry
