I've done it and caught it! It's super easy and I still have it
uuuu.... no you have to do do it in one point of the game. ya know what
1. Fight your way through all of the challengers on Nugget Bridge.
2. Catch an Abra any way that you can, but don't engage the Jr. Trainer (Marked #7) who hides in the grass on the left of Route #24. This will come later.
3. Place Abra in your party if it's not already.
4. Make your way towards that Jr. Trainer, marked #7 on the map on Route #24. He's the one that says "I saw your feat from the grass" when he challenges you. And yes, it says 'feat, 'not 'feet'.
* Save the game at this point.
5. Stand in front of the Jr. Trainer, just outside of his sight. Move down until he sees you. As soon as he does, immediately press Start button. The exclamation point will not be above his head yet, not until actually Teleporting.
6. Select your Abra and use Teleport. If you did it correctly, the trainer should have an exclamation point above his head as you Teleport.
7. For the time being, your menu will not work. This is normal. Proceed to Route #25.
8. Approach the Youngster (#4) on Route #25, but do not battle or talk to anyone else besides the one Mountain Man (#1). You must battle him from as far away as possible. It is impossible to avoid him, but it will still work if you then head to #4. [After fighting the Mountain Man your start menu will be accesible again, but it is not recommended to access it as it is unknown what may go wrong here. Same goes for the Youngster.]
9. You must engage the Youngster in battle from far away. Do not walk towards him and talk to him or the game will freeze.
10. Battle the Youngster and defeat his Slowpoke.
11. Now walk back to Route #24. As soon as you reach the route, your Start menu will automatically appear.
12. Press B button to cancel the menu, and you will instantly be taken to a battle with a level 7 Mew.
13. Weaken the Mew enough to catch it, and it's yours. Normal Poké Balls will not work though, so try something stronger.
I thought about trying it, but I didn't wanna mess up my game so I chickened out.
