How Do I Get Mew Two With No Action Replay?

You can't do it

Go to mt coronet and into the cave where you get the stone plate from the rock and it is in the shape of a square.mew is in that cave and just run around the edges and you should soon run into it.if you can`t find where I am talking about then type in on The home page of google `get a shiny mew and mew 2 ` and it should say somewhere at the top of the page you tube results ` get a shiny mew and mew 2`.click on the picture of the boy in the cave of my description at the start of this anser .IT REALLY WORKS .

P.S. The you tube video will show you how to get a shiny mew two as well!

I tried using that palkia and dialga trick and it didnt work

Get fire red and get two the elite 4 and catch 60 Pokemon and talk to the professor and he will gave the new Dex's and in a a cave  somewhere and he is there I get  him on Pokemon platinum my name is ash

There is no way you can get mewtwo inless you have action replay or if you trade someone

Go to mount coronet, get to the 1st summit, us rosk climb, go left and you should a door. You must have 4 stars on your trainer card. After you go in the door go left use surf waterfall ang go in the door. Have dialga and palkia with you. One of them has to be holding their orb. Go into the door and walk around in squares while staying close to the wall and after you go around 2 or 3 times a shiny mew will apear. Then go out of the room and do some random crazy staps, no running no bike, just walking. The only things you have to have is four stars on your card and a lot of luck. You have to have the mew first. If you have all of the three things and go right left down left 2 steps bla bla bla bla bla. I don't know just walk around therea bunch and eventually you can find a blue or green mew two. I only told you about the mew because you have to have it first.
