You can't catch Mew ANYWHERE. As far as I know, you can't capture mew in pearl, diamond emerald whatever.
Mew can be only downloaded. And that chance is long gone. Mew wasnt even supposed to exist even Nintendo didnt know it existed. but then they somehow found out about it. so they created an event where 100 mews were to be distributed. and that was like 15 years ago.
so mew is a Pokemon that is almost impossible to get. they have tons of rumors about mew glitches and other junk like that. don't believe it they arent real
quick conclusion: no you cant
You'll Have To Catch It With A Pokeball.
Mew cannot be found in Pokémon Platinum, the only way to get Mew in Platinum is either via a cheating device or with an event distribution since Mew is an event-only Pokémon.
Once yo get the national pokedex and bet the elite four you go to profesor oks lab and he will be making a copy of mew then he gives you a egg and in it is mew hatch mew and go back to the lab and he gives you mew2
You can't catch Mew if not through a official Nintendo event or using a cheating device.You cant catch mew. You can only catch mew if you hack.

You cannot catch mew unless you have a cheating device such as game shark. If you do not have the cheating device, then im afraid its impossible to catch mew in emerald. :(
You cannot catch Mew in "Pokémon Ruby."or you can get mew-two in fire red or leaf green.
