its impossible without gameshark or action replay.
you can't, unless you went thru a Nintendo Event.
That guy knows absolutely nothing about fire red. I am sorry, but I do not think there is a way to get Mew without a third party device like Action Replay or GameShark.
you recieve mew from an event that is now long gone, but do not fret, you can still get it from action replay or codebreaker and gameshark codes.
I don't have a gameshark or action replay so are you sure there are no more ways to get him?
You cannot get Mew legit in Pokemon FireRed, for the event for Mew has ended. You would need to use a GameShark or trade for it from Pokemon Emerald.
Use gameshark with a pokemodifier, or trade it from firered or leafgreen.
the gameshark code that alowes you to get mew from under the truck.
It is impossible. Maybe you can trade.
You should look around the island for a old calender then go to the Vermilion town get a ship to birth island and find mew
use a gameshark or action replay u lazy bumb!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
you have to trade from emerald
