by using mews code that should be on the GameShark already and make sure you have the right master code
PS: hope the ^helps
First you go and get a gameshark.
you can only get mew through a gameshark or Nintendo event. here is the gameshark to go to faraway island where you can catch Mew: 8DEB234A 4C8DC5EC
You can't get mew with out gameshark codes in any of the Pokemon games.
Gameshark or action replay
yes there is by using GAMESHARK!
I don't have a gameshark or action replay so are you sure there are no more ways to get him?
After getting the eighth gym badge, all pokémon will obey you, with the exception of Mew. The only way to make Mew obey you fully would be to use the 'Box 1 Slot 1' Mew cheat on Gameshark/Action Replay. -------------------------------------------------------------------------------------------------------- I have a Gameshark and the Box 1 Slot 1 cheat copies the pokemon in question but will NOT make Mew obey. If you have a Gameshark find a version of emerald and warp to Faraway island. Catch Mew, trade mew, copy mew. Now you have many mews and they obey.
You can't catch mew on leafgreen you need gameshark codes for that
you have to trade from emerald
