Catch Pokemon without weakening them:
Save a lot of money (around $10,600) and buy all the Pokeballs. You should have 99 -- as long as you have at least 85 you can still use this without having to buy more. When you encounter a Pokemon, start throwing Pokeballs. If on the first try, it says you missed the Pokemon, do not try it again -- weaken it or use a better ball. If the Pokemon breaks out of the ball, keep throwing Pokeballs. After a while the Pokemon either gets tired of breaking out or finds a ball it likes and will not bust out. You can use this trick with a Great Ball or Ultra Ball, but it will be more expensive.
Catch Pokemon easily:
When you throw a Poke Ball, Great Ball, or Ultra Ball, hold B when the ball just starts to explode. An Ultra Ball is recommended.
Get into a battle with a wild Pokemon. Use any ball (except for a Master Ball) immediately as an attack. As soon as the ball appears, hold B + Up. This requires extremely precise timing.
Use False Swipe until there is 1 HP remaining, then paralyze them. This will make it harder for them to break out.
Use this trick to catch Zapdos, Articuno, Moltres, and Mewtwo easily. You need are a lot of Pokeballs and you need a Haunter at level 35 that knows Hypnosis. Go to any of the legendary bird Pokemon, and save the game before you battle. When you start, make sure you have Haunter in front, and quickly use Hypnosis. If they attack you, Haunter should not faint. Once they are asleep, you do not need to weaken them; just throw a Pokeball. When battling Mewtwo, level up your Haunter to about level 45 and do the same thing. If you cannot catch it with a Pokeball, try a Great Ball.
Catch the legendary birds easier:
It is much easier to capture them in order of Zapdos, Articuno, and Moltres. Once you have captured Zapdos, use an electric attack (except for Thunder) on Articuno. This should put it in the red zone, making for an easy capture. If you use Thunder, it is likely that Articuno will faint immediately. Use Articuno to capture Moltres. Use Ice Beam as opposed to Blizzard, as Blizzard will be too strong. If you are not looking to fill your Pokedex, still make sure that you have at least Zapdos and Articuno. Zapdos is very useful for defeating the Elite Four, as it can take down Lorelei's, Bruno's and Agatha's Pokemon as well as Lance's Gyrados. Articuno can take down Lance's Dragon family (Dratini, the Dragonairs and Dragonite) by using Ice attacks.
Check Ghost Pokemon without the Silph Scope:
You can see the Pokemon Ghosts in Pokemon Tower without the Silph Scope. When you are in battle choose PKM menu as if you were going to change Pokemon. Instead, just check the stats of any Pokemon in the party and go back to the battle. You will see the Pokemon that is there. Note: It is impossible to catch them, but it will be registered by your Pokedex.
Defeating Ghost Pokemon:
Use a ground type move such as Dig or Earthquake.
The only ghost Pokemon are Gastly, Haunter, and Gengar. They are also Poison-type. Psychic type Pokemon are weak against Ghost attacks, and the opposite is also true.
Catch a Caterpie in Viridian Forest. Advance it to level 7 and he will evolve into a Metapod. Advance it to level 11 and it will evolve into a Butterfree. Butterfree can beat JR. Trainer and Geodude. Butterfree will have to be at least level 13 before it can beat Brock. Note: Use your Pikachu's tail whip to lower their defense.
If you look in the tall grass west of Viridian CIty a lot, it is possible to find a Mankey. Since fighting types beat rock types, Mankey is the best Pokemon for the job. You need to raise it to a high level though, because it does not learn a fighting type attack for a while.
Catch a Pidgey and train it up to level 18. You should have an easier time defeating Brock.
Go to Viridian City. Enter the grass by the Pokemon League. Keep battling until you find Mankey and try to catch it. Train it until it learns a fighting or ground attack, like Low Kick. Go to Pewter City and fight Brock. Put your Mankey out first to defeat Geodude. Then, switch to Pikachu and use Tail Whip until Pikachu faints. Use Mankey again keep using Low Kick until Onix faints.
Use a Pidgey and advance it to level 13 or 14. Catch a Caterpie and evolve it to a Metapod, and a male Nidoran. Use all four of them in battle with Brock. Use your Pickchu's Tail Whip to lower Geodude/Onix's defense. If it faints, use Metapod's String Shot to lower its speed for slower attacks. Once the "Nothing Happened" message appears, use Nidoran's Leer to lower Geodude/Onix's defense.
Get a shiny Nidoran and train it until it learns Double Kick. It should already know Horn Attack. Use it to defeat the apprentice. When facing Brock, use Double Kick on all of his Pokemon.
Catch a Mankey west of Viridian City, in the grass below where you battle your rival. Train it to level 9 and let it learn Low Kick. Then, use Low Kick to beat the Jr. Trainer and Brock.
Choose Gary's Eevee's evolutions:
You can choose Gary's Eevee's evolution by how you do in battles with Gary's Eevee. To get Vaporeon simply lose the first battle with Gary in Oak's Lab after you deliver Oak's Parcel. Then, win the battle near Viridian City on the route to the Pokemon League. To get Flareon, win the match with Gary at Oak's lab, then lose any of the other matches, except for any of them past Silph Co. To get Jolteon, win all of the matches.
Defeating Gary's Eevee evolutions:
When battling Gary's Eevee evolutions, use the following strategies.
Eevee: Have a Geodude that knows Dig. Normal move are not effective against Rock Pokemon and ground is very effective against normal.
Vaporeon: Use Pikachu, or Bulbasaur.
Flareon: Use Squirtle or Geodude. Water is very effective against fire, and ground is also very effective.
Jolteon: Use Graveler that knows Dig. That is very effective.
Jesse and James locations:
To find these team rocket members, go to these locations:
Mt. Moon (before you exit)

When facing a Pokemon (except for special ones, such as Mewtwo) throw a Pokeball of any kind at the it. As soon as the Pokeball pops open hold B until it wobbles for the second time. For Pokemon such as Mewtwo, reduce half their HP, then do the trick.
If one of your strong Pokemon gets poisoned during a battle, just keep using a move that can cause an instant K.O.. If you keep knocking out the opponent's Pokemon one after another, the poison will not work. Also, instead of pressing and holding the D-pad, tap it to take small steps.
Keep the S.S. Anne at Vermilion City:
Save your game before going on the S.S. Anne. Once inside, get any desired items, including the HM01 (Cut). Before you exit the S.S. Anne, battle a trainer and get all your Pokemon knocked out. You start back at a Pokemon Center, with the S.S. Anne still at Vermilion City. Return once you obtain a Pokemon with Surf and visit the immovable truck.
Shortcut to Cinnabar Island:
After getting SURF, go to Pallet Town. Surf down the river at the bottom. After a few attacks by other trainers you will arrive at Cinnabar Island.
Safari Zone time:
The time as most people think it is, is not really a time. Every time you move one space it subtracts one of your moves (or seconds). This is why if you are fishing, it does not take up any of the moves (or time). You are just standing there.
Items in Viridian Forest:
When you walk into Viridian Forest, you will see a tree with someone in front of it. Go to the left side of the tree to find an Antidote.
After getting the Pokedex, leave Viridian City . The old man will try to catch Rattata but unlike in the Red/Blue version, it will breaks free.
The old man does eventually catch Rattata. After about three or four times talking with him, he throws the PokeBall and catches it.
No more tall grass:
Teach CUT to a Pokemon, then get the Cascade Badge from Misty. Walk up to the tall grass and cut it.
Your Pokemon can be printed at the Pokemon Club in Vermilion City.
Level 100 Pokemon:
This trick requires a link cable and the Red/Blue version. Go to a Pokecenter and trade one of your Pokemon to the Red/Blue version. Make sure you have 99 of any item in Red/Blue version. Make that Pokemon in Red/blue version to level 100 and trade it back to the Yellow version. Note: This trick requires a lot time, but is worth it.
If you do not want fight all the gym leaders or people who want a fight while wandering in the cities, just avoid them by walking past while they are looking away.
Remain in secret room:
Note: This trick requires a link cable. Link to another Game Boy and begin the game in the Pokemon Center. Go the secret room and remove the link cable. You and your friend can still play in the secret room.
The Unknown Dungeon is completely different from the Red/Blue versions, however Mewtwo is still located there.
The truck that was next to S.S.Anne in the Red and Blue versions is here in the Yellow version, but still can not be moved.
Using the link cable to build your starting team:
If you do not want to lose any Pokemon you really like and want to restart a game, trade the Pokemon from one game to another. To do this, go to a Pokemon Center and trade. Trade the desired Pokemon for a bad Pokemon from the other game. Repeat as many times as necessary, then restart your game. Get your Pokemon back from the other Pokemon game. You can do this to construct an almost invincible team.
Keep old Pokemon or create duplicates:
Note: This code requires Pokemon Stadium and the Transfer Pak. Before you restart your game, put the Pokemon you want to keep into boxes on Bill's PC. Then, transfer your game onto the Nintendo 64 and go to Professor Oak's Lab. Once there, use the computer to transfer the boxes from your game onto the Nintendo 64 boxes. This will cause all the Pokemon you want to be saved to be placed on the Nintendo 64 instead of your Game Boy Color game. Then restart your game, and once you save, go back to Professor Oak's Lab in Pokemon Stadium. Transfer all the boxes from the Nintendo 64 to your Game Boy and save. This will add all those Pokemon into your Pokedex, and you will be able to use them in your game -- although they will most likely not listen to you until you get Misty's badge.
Place the Pokemon that you want to level up at the top of your list. Fight the Elite Four, then switch to the Pokemon you want to win with, and bring it out. Keep repeating this with every trainer and Pokemon.
Easy Coins in Game Corner:
Go to the Game Corner, with all the slot machines. Walk around the room, continually pressing A. Sometimes you will pick up some coins off the ground - a message will appear. You can get over 200 coins this way.
Even odds on slots:
There is a man wearing glasses that resembles the man at the entrance of the Gyms. Talk to him, then go to the slot machine just above him. Start with 50 coins and eventually you will hit three jackpots in a row. Your odds will be 50% as good. If you run out of coins, just repeat those steps.
Really catch mew
For this cheat to work you cant have battled the gambler under the underground tunnel on the right of saffron city, or the fouth traner (i think) he is a boy on the area above nugget bridge (right of bills lab), well back to the code. Enter the underground tunnel left of saffron (right of celadon) exit the other side and stop. Imediatly save. take one step foward and imediatly (i mean imediatly) press start. once you fly he will see you and start to walk up, but it is too late for him to battle you. fly to cerulean city and go up nugget bridge (notice your start button does't work, if it does you screwed up) and go to that fourth trainer i said. Dont walk up to him, go as high as you can above him and let him battle you. (if you go up to him your game will freeze) beat him and the imediatly fly to lavender town. go to the route on the left of the city and the start button will pop up by itself. fress b (no other button) and you will interach with a pokemon. it is mew at LV. 7. trust me he is very good. This cheat will work on all pokemon yellow games.

HM 1 - Cut
The HM 1 move cut, as we know, can cut down trees in the way. However, I have discovered that it can also cut the patch of grass. Just stand on a patch of grass and use cut to cut away the grass in your way and avoid wild pokemons.
