As I type this, I am beaming. Not only did I achieve the Mew Glitch, I actually did it TWICE. Months after getting Mew the legal way via Nintendo for Pokemon X and Omega Ruby, I found the Yellow cheat on my 3DS, and will now share with you how you can try this at home.
Let me be VERY clear. This is NOT a "quick" cheat. In fact this was several hours of work for me to get it just right, so please do not get frustrated if after a few hours, you're still Mewless. Be patient and do everything I tell you EXACTLY as you are told to do it and I promise you, your rewards will be well worth it.
All you need is a Nintendo 3DS and Pokemon Yellow on it.
That's it. No cheat devices. NONE.
If you want to be really fancy, you CAN use a GameBoy, Super GameBoy, GameBoy Pocket, GameBoy Color or GameBoy Advance with the GameBoy Color edition of Pokemon Yellow, or any other GameBoy player with the GBC port of Pokemon Yellow, but for those of you on a budget, the 3DS version will suffice.
To do the glitch, you need to have JUST ENTERED Cerulean City for the first time. If you have already battled everybody from here to Bill's house and beyond, I'm sorry, but you failed. You'll have to start over on a new game file.
You'll need to trigger certain story events as well. This glitch is a little harder than it is in Red and Blue, so please bear with me.

First, heal your Pokemon at the Pokemon Center and then buy some potions and Pokeballs.
SAVE YOUR GAME
Then, head towards Nugget Bridge and defeat your rival.
SAVE YOUR GAME
Then, head towards Nugget Bridge and defeat your rival.
His Eevee is arguably his best right now and his team are in the teens. If you're not feeling comfortable sending your Pokemon against him yet, exit Cerulean City and head back towards Mt. Moon for training. But if you've faced most of the Team Rocket grunts back there, you should be ok.
Beat everybody on Nugget Bridge. It is okay if you need to heal your Pokemon between battles and save. You need to clear the bridge to get the prize.
You will get a nugget, but you'll have to fight a Rocket Grunt for it. Take him down, then sell the nugget to buy more Pokeballs. YOU WILL NEED THEM.
Once you have crossed Nugget Bridge, STAY AWAY from this area pictured. You will need it later for the glitch to work. Instead, you may go up, grab a free Charmander, and then head east.
Battle everybody EXCEPT THIS GUY!! Use the illustration above to keep away from his line of vision. Don't talk to him, don't walk in front of him, just act like he's not there. Follow my arrow. He's part of the Mew glitch.
Go to Bill's house. Pikachu will act curious around him. Tap the A button by his keyboard to get him free. After a bit of banter, exit the house. Why are you here? Because of Officer Jenny, I'll explain shortly.
Follow the diagram above. We are still avoiding that one trainer. Go directly to Nugget Bridge and then back to the Pokemon Center to heal and save.
When you first got to Cerulean City, Officer Jenny was blocking the door to this house where a robbery took place. Talking to Bill prompts her sprite to move over, allowing you access into the home. You will head straight out the back door and battle the Team Rocket grunt in the backyard.
After defeating the grunt, continue through the backyard and down this path shown.
You will see three ledges, each with a patch of grass. Jump down to the third one, directly above the Day Care house. This is where you will find Abra.
THIS IS TRIAL AND ERROR!! In order to find Abra, I wound up fighting and catching Jigglypuff, Rattata, Pidgey, and Pidgeotto before finding Abra. Abra only knows one move, Teleport. He'll flee for no reason from you, so you may need to face more than one Abra.
I caught mine by having Pikachu use Thunder Wave to paralyze him, and then tossing a PokeBall. Some have had luck by using Clefairy or Jigglypuff's Sing. Again, be patient.

Once you have caught Abra, SAVE YOUR GAME!!
Head back to the Pokemon Center, heal your team and put Abra on your team. Buy some PokeBalls and then go back to Nugget Bridge. It's time to activate the glitch.
BEFORE YOU DO THAT you might want to switch to Box 2 on Bill's PC in the PokeCenter, just in case Box 1 is filled up. If your main box is full, you cannot catch Mew unless you have an open spot on your team.

Save your game RIGHT HERE as pictured. This next part is very tricky and it's very easy to mess up, so saving here will save you valuable walking time in case you have to reset your game.
Press Down and Start at the exact same time. In rare cases, you can hit Start just SLIGHTLY after Down. If you did it right, your screen will match the picture here above this text. Your menu should pop up, and there should be a trainer head coming towards you. If you get the exclamation point instead, you messed up, try again.
Have Abra teleport you to the PokeCenter. From there, walk back up Nugget Bridge. If the glitch worked, you will not be able to use the menu AT ALL. Do not panic, this is normal and it will come back after you catch Mew.
Go east to the trainer I told you to stay away from. Walk against the wall above him until he walks to you. DO NOT try to talk to him first via the sides, or your game WILL crash. Defeat him, then try to walk back to Cerulean City.
As you walk, your menu will suddenly pop up. Exit the menu. Mew is about to appear.
The screen will flash and Mew will appear. He is level 7 and only knows Pound. Use Pikachu's Thunder Wave to paralyze him, and then use a weaker Pokemon to use Pound or Tackle on Mew. Any light attack that will not knock him out.
Even though he is paralyzed, he will still hit you back 90% of the time.

Get his meter to a low yellow or a red before throwing PokeBalls. My first Mew blew through about 12 PokeBalls before finally staying in one.
If you are on the 3DS, hold down on your circle pad once he is inside the PokeBall but just before the struggle. I don't know why, but for once, this old trick actually kept him inside a ball for capture.

Go back to the PokeCenter, heal and then go back up Nugget Bridge. It's time to trigger the second Mew. You will save your game at the same spot to the left of Nugget Bridge, and you will again try to trigger this trainer without actually battling him. You will again hit Down and Start together, triggering the above screen. You will again have Abra teleport you back to the PokeCenter.
Battle the first trainer in Misty's Gym. He will come to you. DO NOT BATTLE ANYBODY ELSE!!
Go back up Nugget Bridge after you beat him. Your menu will pop up again. Exit, and the battle screen flashes.
Yes, I did make my newly caught Mew fight the second Mew. Why wouldn't I? This is a once in a lifetime experience, I'd be crazy to pass this up! Using the same method, I caught a second Mew.
After that, I saved the game and got greedy. Once again, I went back to this guy over here and hit Down+Start before he could touch me.
This time, after Abra teleported me back, I let the second trainer walk to me at Misty's gym.
But this time, I only caught a Staryu. After catching him, I saved, healed and then went after Misty.
Her Starmie got poisoned by my Nidorina, but she fainted. So I brought out my Magikarp and defeated Starmie with Tackle. Look at Misty. She is SO pissed right now that a Magikarp took down her souped-up Starmie. Laugh at her pain. LAUGH I say!
To celebrate my ridiculous win, I activated the glitch again with the trainer in the grass, then walked aaaaaaallll the way down through the underground path, let a trainer walk up to me, beat him, and then I walked aaaaaaalll the way back to Nugget Bridge, where my menu popped up.
This time, I found a level 7 Grimer.
And this is why we change our boxes, boys and girls. The struggle is real. Fortunately, I reset my game, switched boxes, and was somehow able to get Grimer again when I repeated the last few steps.
As a general rule of thumb, once you activate the trainer in the grass, you should ONLY fight a trainer who walks up to you right after you trigger the glitch. Failure means a crashed game. Let the trainer come to you, not the other way around.
So now you should have two Mews you can train in any way you want. Mew can learn all TM and HM moves, so feel free to mix it up. You can raise a Mew that knows Bubblebeam and Thunderpunch for example, even though they are a psychic types! Raise them well, so that when it's time to send them to Pokemon Bank for Sun and Moon, they'll be ready for anything.
