The Mew Glitch
The Mew Glitch is a name given to several glitches that allow a player to obtain a Mew without the aid of a cheat device.

To properly perform this glitch a player must have had acquired the HM containing Fly, and must have avoided the Youngster on Route 24 and the Gambler near the underground path, left of Saffron City, until ready to perform the glitch.

First, a player must stand above the Gambler so that he is no longer visible. Next they must take a step down at him and quickly press start to open the menu (Note: If the Gambler spots the player the glitch will fail). While the menu is open, Fly to Cerulean City and battle the Youngster on Route 24 that was avoided earlier (Note: When going to battle the Youngster, the player must be a few steps away from him so that he walks to the player. Standing right in front of him will crash the game.). After defeating him, Fly to Lavender Town and walk onto Route 8, this will cause the start menu will pop up. Press 'B' to exit the menu and the player will be put into a battle with a Lv. 7 Mew.
