Well there is an easy way to get Mew without a Nintendo event. When you get to Cerulean City and start to head north to get your S.S Anne ticket from Bill. Defeat the Nugget Bridge.You will see the man standing in the grass off to the left of the bridge, DO NOT FIGHT HIM! Then on the path that is off to the right where there are a lot of trainers, there is a trainer looking up towards the back wall and his only Pokemon is a slowpoke, DO NOT FIGHT HIM!Just be sure that you are ready and can walk up to slowpoke boy without fighting anybody. (Pokemon Centre-Slowpoke boy)Now if you have done all of that, you are ready to catch your very own Mew1. Catch an Abra and put it in your party2. You have to go up to the trainer off to the left of the bridge (in the grass) stand so that if you walk one step down you would have to fight him.3. Save your game so you can just reset your game if you screw up.4. Now, walk down as if you are going to fight him but just as you stop press the "start" button and your menu will pop up before the trainer sees you.5. Now select Abra and use his Teleport. You will notice the trainer tries to walk up to you anyways6. Now you will be in front of the Pokemon Centre and you will notice that your start menu doesn't show up when you press start (don't worry it's supposed to be like that). Don't go to heal your Pokemon or anything.7. Walk back up and go to fight Slowpoke boy. Walk against the wall to make sure that HE WALKS UP TO YOU. 8. Then once you defeat him you will be able to open the menu up again. Open it and use Teleport9. Then walk up to the bridge and your start menu will open on it's own. Close the menu and voila a wild Pokemon. It is a level 7 Mew. P.S to catch Mew you wont have to damage it that much
