Beat Brock
When you pass the woods and get to Pewter City, You will have to battle Brock the Gym Leader. He uses rock type so Pikachu will be usuless against him as electricity dosn't effect rock. In some of the other cheat codes it says to use water or grass type but you cannot find water or grass types that early in the game. So I caught a Nidoran (girl or boy, it dosn't matter) and trained it untill it learned double kick. Double kick is a fighting attack which is super effective against rock.
How To Get Mew
Ok, this cheat is probably one of the only Mew cheats that actually works, and it's only for Pokemon Yellow! First you have to have a Pokemon that knows Teleport. Then go to Cerulean city, but don't go in the gym just yet. Instead, go up Nugget bridge, and to the right will be a grassy area and a trainer. Go up past the bridge and go to the part where you're facing the trainer, but he can't see you (he'll just be off-screen). Then take one step forward and QUICKLY press start. Use teleport and you will go back to the Cerulean Pokemon Centre. If you try to press the start button, you will realise that it won't work. Go into the gym and fight the first trainer in the water. Go outside and head up Nugget Bridge. Your start screen should pop up as soon as you step on it. When it does, press the B button and you will battle Mew! Mew is only at level 7, but he's worht it! And I'm pretty sure that this glitch won't hurt or erase your game, unlike Missing.No. Trust me, this cheat works. I read it on a forum, and i was a little skeptical myself, but i started my game over again and it really worked! Now my Mew is at level 57! Try it yourself!

How to get two HMs in Fuchsia City
If you are stumped on where to get the "Surf" HM, Here's what you do. It's in Area 3 of the Safari Zone. You will have to get there fast as well. (I used a bike, I suggest you use it if you have it.) If you get into the secret hideaway in area 3, the man will give you the "Surf" HM. The gold teeth item is also in Area 3. Give the gold teeth to the owner of the Safari zone and he will give you the "Strength" HM. Use that to move the boulder and claim the item in the owners house.
Get Squirtle
To get Squirtle first you must beat Lt. Surge. Then go talk to officer jenny in the middle of the city and she will give you Squirtle.
Get Raichu
To get Raichu, trade the Pikachu you started with to a Red/Blue version after It gets to be about Lv. 50-60. Then use a Thunderstone on the Pikachu you traded. After it evolves, trade it back to Pokemon Yellow. Now you will have Raichu. Be careful, though. Pikachu will no longer follow you around if you do this. You may be much better off just trading a Pikachu caught in Red/Blue and evolving that one.
