Mew Glitch/Ditto Glitch
Make sure you never fought the Trainer Jr. on route 24 with the slowpokes. If you have than go to the part where I mention IF YOU HAVE FOUGHT TRAINER JR.
First off make sure you can find a trainer you can battle who is off screen (prefer the one trainer who is in the tall grass going down the path that takes you near the cave to get Mewtwo) and save your game right here. After saving walk in the direction of the trainer that would make him appear and also will let him spot you. As soon as you press the direction of which he appears press start and fly away to Cerulean City when done right the trainer will not spot you as you are paused and as soon as you fly away he will spot you but will not engage a fight. Your start button will no longer work now. Head towards where the Jr. Trainer is with the slowpokes and fight him BUT make sure he walks towards you if he doesn't walk towards you and you are right in front of him the game will freeze. Fight him then fly back to Cerulean City. Now walk up the bridge that would lead you back towards the guy you flew away from and about half way up the bridege your start menu will pop up cancel it out and Mew will appear. If you evaded away from a different trainer then the one I told you about you must go to where the trainer was and figure out yourself where to go so the start screen appears.
IF YOU HAVE FOUGHT TRAINER JR.
Oh well looks like no mew for you.... unless you do the ditto glitch.
THIS WILL NOT WORK AT ALL IF YOU HAVE FOUGHT EVERY TRAINER IN THE GAME!
First you need a Pokemon with a special stat of 21 that is the most hardest part. Then locate someone who is off screen and save the game here. Walk in the direction in which he will appear and spot you. As soon as you walk in that direction press start and fly away. You will know you did this right when he appears and instead of the trainer spotting you your pause screen pops up instead and when you fly away he will spot you. YOUR START SCREEN WILL NO LONGER WORK! Make sure the area you are flying to has trainers to fight. find anyone to fight and now go find a ditto. when you spot a ditto it is smart to have a Pokemon other than the one with the special stat of 21 to go out first instead so that way when you find a ditto you switch out the one for the special stat 21 pokemon. Ditto will transform into your Pokemon with 21 speical stat. Kill it. Then fly back to wherever you flew away from battle. when you are near the area of the evaded trainer your start menu will pop so close it and BAM! Mew.
Also I would look up the ditto glitch on google because you can get any Pokemon in this game without needing a red version or trading Pokemon for those who can only evolve through trading.
