Note: This trick could corrupt your saved game file. Put the Pokemon you want cloned in an empty box on Bill's computer. Then switch to another empty box. When it asks you to save select "Yes". Once it says there is another file, select "Yes" and at the same time turn the power off on the Game Boy system. Make sure the power is off before more text comes up or you will not get the cloned Pokemon. If done correctly, you will have the Pokemon that you cloned in your party and another one in Bill's computer where you deposited. This trick also works on items.

Go to the item that you want to be duplicate. Note: You cannot duplicate items in Poke Balls, such as Rare Candy. Then get the password to reset the time and change the day. This works best with berries and balls from Kurt.

Go to the Underground Path in Goldenrod City on Monday. Buy a Nugget and attach it to a Pokemon. Use the duplication trick as many times as needed. Detach the Nugget(s) and sell them for $5,000 each.

Go to Ecruteak City, then go inside the house with another house beside it. Climb up and enter Tin-Tower. Climb up until you get to Ho-Oh/Hou-Hou. Note: You must have the Rainbow Wing. You can get this from the Station Manager after beating the Rockets in the Radio Tower. You do this after beating Mahogany Town gym.

Go to Pewter City and talk to the old man that walks around. He will give you a gold feather. Then, go to the place where Ho-Oh/Hou-Hou is located in the Gold version to find it.

Equip Seadra with the Symbol of King's Rock, and then trade it.

Enter the Union Cave on Friday and go to the pool in the lowest left side on the first floor. Surf across the pool to a ladder. Climb the ladder, then Surf across the pool. Go up the new ladder. Surf to the middle of the pool. Now go left to shore. Walk down until you get to another pool. You should now see Lapras. Note: There is only one, however there will be a new Lapras every Friday.

Learn HM06 (Whirlpool) and go to Cianwood City. Destroy a whirlpoor and enter the cave. Go through the maze and you will reach Lugia.

Go to Pewter City and talk to the old man. He will give you a silver feather. Then, go to the place where Lugia is located in the Gold version to find it.

Transfer a Pikachu from Pokemon Yellow into the game. It should have an item directly translated to "Electric Ball". Equip it to any Pikachu, and its special attack will double.

Go to the Lake of Rage in Mahogany Town. Surf the lake until you see a strange red Gyarados. Fight him and catch him.

Go to Victory Road where you go to get to the Elite Four. You should encounter a silver Rhyhorn.(It takes a lot of time becuse it is a random pokemon like any other colored pokemon)

Equip the King's Rock on Slowpoke, and then trade it. It will evolve into Slowking/Yadoking.

Breed Jynx with Ditto while looking at your party to get Smoochum/Muchuru.

Equip the Metal Coat on Onix and trade it to another Game Boy. It will evolve into Steelix/Haganal.

Go to Ecruteak City, then go inside the second cave (second entrance to Mt. Mortar), turn to the right and Surf. Go to the top and enter the other cave that is there. Make your way around the mazes and talk to Blackbelt Kyo. Defeat him to get Tyrogue/Buruki. Note: Make sure you have an open space in your Pokemon holder.

Go to Saffron City before fighting Sabrina. Challenge Sabrina to discover that her Mr. Mime is female.

When you go to Enjyu City, go to the tower and your rival will appear, but will not battle. However, if you first heal your Pokemon at the Pokecenter, defeat the Ghost Gym Leader, and then go to that tower, your rival will talk to you and fight.

Go to Saffron City and talk to the girl copycat. Fly to Vermilion City and talk to everyone in the house where you received the bike voucher. Someone will give you the Clefairy doll. Take it to the copycat to get the monorail ticket.

Collect all eight badges, then talk to Professor Elm (the person from the start of the game). He will give you the S.S. Aqua ticket. Go to Olivine City where the Gym Leader was first not there. Go inside the house at the shore, the person will let you go through, and you will be on the S.S. Aqua. You will meet a man that wants you to find his daughter on the ship. You can find her with the captain. Return her to her father to receive the Metal Coat.

Go to the town where you had to rescue the Slowpokes from Azalea Town. Enter Slowpoke Cave where you got the Slowpokes from the two Rockets. Use Strength and push the boulder, then Surf in the pond. Find the ladder, go to it, and Surf. Talk to the person in that part of the cave. He will give you the King's Rock.

First, solve the Kabuto puzzle, which you should know how to get to. The rest will require the HM for Surf, found in Ecruteak City, TM08 (Rock Smash), and the HM for Strength. Surf down by the Ruins of Alph (Violet City) and solve the puzzle there. The puzzles should be somewhat easy. Just put in the corner pieces first. Then, go to the Union Cave. Walk around and find the Pokemaniac. If you have not defeated him, fight him. Then, Surf in the waters near him. You will have to return here twice. Break the rock you find, and solve the puzzle. Then return, move the boulder, and solve the last puzzle. Catch three Unown, then exit the ruins. Talk to the scientist near the cave and he will give you a complimentary Unown Pokedex.

While in the Ruins of Alph southeast of Violet City go to the Pokegear option in the menu screen. Go to the radio option and on the fourteenth to the twentieth channel you can find a station Called ??????. That is the Unown Music. It can only be heard at Ruins of Alph.

You cannot breed every type of Pokemon, although some are male or female (like Mewtwos). They still cannot be bred together.

You do not need another of the same Pokemon to breed. Get the Pokemon you want to breed and put it as male or female. Get Ditto, place it with the male or female, and let the breeding begin.

When you use the Time Capsule to trade with the other Pokemon games, every Pokemon that comes from the Red, Blue, or Yellow versions will have an item equipped with them. Some will just have berries, but others have better things.

Create a Pokemon team with different types; Grass, Psychic, Devil, Fire, Water, and Steel recommended. Each Pokemon should be level 65 or higher. If not, make sure you have a large amount of Hyper Potions and Revives.
