In game, no one will. If you have a friend or another game you can get one from them/that. If you have another game then restart (if you really want a Treecko), pick Trecko, and trade it over.
no not if you are goin to trade in a used one ...
You can migrate GBA Pokemon to a DS Pokemon game but you can't trade using the GBA game trying to trade with another GBA game.
Transfer one from another game or use the global trade in the pokecenter to trade another pokemon to get a noctowl
in order to get another master ball the only way without cheating is to trade one from another game to the game you want it in.
No. You will need to trade one over from another game.
Yes, you can. It's called Migrating.
Trade one from a friend or someone u know,or breed one yourself.
no where, thats the only one in the game if you dont trade over game.
One way is to trade with another emerald or you could trade your latias (or latios) to another emerald then restart the game and choose the opsite then catch it and trade back.
no only one unless you trade it from another Pokemon game
You need to trade one from another game.
