Before this glitch was found in generation 1 games, the only way to catch Mew and complete the pokédex was from special promotional events from Nintendo, the last of which ended in April 2000. While Mew is not needed. Obtained from the lead developer of the game Freak in the Celadon Condominiums, it is a must have for a pokémon complementer and battles, as its base stats are rivaled only by the legendary Mewtwo.
How it works
When you first catch the concept of Mew, you can actually catch the Mew glitch in the game of pokémon, as long as certain conditions are met. The glitch itself consists of three important parts, each of which must be completed in the correct order for the glitch to work properly.
The first player must access the Door, Fly, Dig or Rope to escape. In addition, you will have access to opponents who will see your behavior and walk towards you as soon as you come within their sight. The NPC should approach you from the top, left or right; teachers coming from the bottom of the screen will not work.
As soon as the NPC appears on your screen, first click the SEND button. If the timing is correct, the map will open before the NPC to take action. From the menu use the Door, Fly, Dig, or Escape Rope to head to another location. Any location will do, as long as you find another trainer from that location to fight. If done correctly, “!” A trainer will appear above the head of an NPC indicating a fight as you run away. Note that after you run away from this initial trainer, your ORIGIN button will not work until you fight an additional trainer.
Once you reach your new location, you must fight another trainer to regain access to your home screen. It is also necessary that there should be an exerciser here to walk with you; You cannot engage in combat from an immediately opposing space.
To complete the glitch, you must return to the path where the trainer first encountered the one you ran away from. After entering this route, a menu will appear. Closing the menu will start a battle with a pokémon whose identity depends on the special state of the last pokémon it encountered. This special status can be drawn from the last trainer pokémon you just fought, or it can be a wild pokémon if you encounter one. Both will work and both methods of catching mew can be used.
Mew caught in the game . at first
Requirements: An Abra with the Doors. Ability to fight Swimmer in Gym Cerulean and Jr. Trainer on Route 24. Pokéballs to catch Mew.
Place Abra in your party and heal your pokémon at the Cerulean City pokémon center so you can get them back there later. Defeat Nugget Bridge normally if you haven’t done so before. Head to Route 24 and stop on Jr. The trainer is just off the screen. Keep your game (if you mess up on this second part, it involves a good sense of fear). Move one space and as soon as you see Jr. Trainer press the start button. A menu should appear and you need to use the Door. If done correctly, an interjection animation will appear above Jr.’s head. A fleeing trainer will appear.
As soon as you arrive at Cerulean City, head east to the pokémon center and swim into the gym there. After defeating Nanti, head to route 24. After walking a few steps, a map will appear. Closing the menu will start the battle with Lv 7 Mew.

using the glitch to catch other pokémons
You can use an alternate version of the glitch to capture any pokémon in the game, since the wild pokémon’s identity depends on the special state of the last pokémon it encountered before the glitch activated.
