ANother Way! :)
There another way called the TMG (Teleport Mew Glitch) and this is how to do
it. this works the first time when you go into cerulean. Ok, when you enter Cerulean City go to the Pokemon Center and heal even if
you have full hp. Then once you've done that, make sure you have 4 or less
pokemon. If not put enough in your PC so you have 4 or less pokemon. Then once
you have done that, head out and go north to nugget bridge. Then your rival
should come up. Beat him and go heal if you have to otherwise go and beat the 5
poeple on the bridge and the rocket person that gives you the prize (nugget)
After you beat him, SAVE IT. Once you have done that head north then left over
the river so your right next to the mountain. Then if you go down you should see
a guy hiding in the grass. DO NOT VERSE HIM. If you did, turn your gameboy off
and on and do it again. Instead of versing him. Keep walking around in the grass
untill you find an Abra. Then catch it. I have heard that you can only catch
Abra there only in Red and Blue. As for yellow, I think, that you can catch it
on Route 8. Well once you have caught it, save it. Abra should be in your
line-up now. After that head north just one step/screen above the guy in the
grass. Take one step to the right so that you are now directly above him but he
is still off your screen. *NOTE: If you verse him during the process of doing
this, turn you gameboy off and on.* So now that you are above him but cant see
him, press down and then press start quickly after you press down. If you did it
right, your start menu would now have popped up and you are able to see the guy
left of the start menu. If you did it wrong turn it off and on. Now that your
menu is up. Click POKEMON, then go to Abra and click Teleport. The guy will see
you just as you teleport away. Now you should be at the pokemon center without
the start button functioning. Now head back to nugget bridge but this time take
a right. You should come upon 2 hikers. Try to avoid them and find a way
through. It is okay i u fight one of them. It works this way also. After you have passed 3 trainers, you will see 2 more trainers. A boy
and a girl. Now we have to verse the boy. DO NOT WALK UP TO HIM otherwise your
game will freeze. Instead, simply walk up then right and make him walk towards
you. So now you are in a battle. He will send out a Slopoke. Beat him. After you
have beaten him, your start button will start to work properly again. So press
start and Teleport to the Pokemon Center again. Now if you haven't already,
stack up on pokeballs at the mart. You should have at LEAST 5 pokeballs. Once
you think you are ready, SAVE IT, cause if you mess up you would have to do it
all over again. Now head back to nugget bridge. Walk north to the bridge and
your start menu will pop up. Simply press B and await your Mew battle.
