When you breed fe. clefairy and jigglypuff, and the mother ( female pokemon ) is clefairy, u will have clefa in egg. If jiggly is female, ull get igglybuff in egg. Simple?

Female + Male = egg = female

First, you need to have a gastly or haunter that knows mean look. Mean look prohibits wild pokemon from fleeing during a battle. Then equip your pokemon with quick claw so it can go first. So when you see a legendary dog, you can be able to fight it and hopefully catch it without it running away.

When you walk up to the edge of grass use cut and the grass will be gone. No more random battles.

First, go on the S.S. Aqua on sunday or wednesday, save the game and wait until the next day.

Now Some of the Cheats say that you can get some kind of virus in the pokemon games...lol well if you really want perm boosted exp all you need to do is get a pokemon from another game (the ID number and the OT must be something else and when you beat a pokemon it will say {pokemon name} gained a boosted exp points!

this is true cuz I trade pokemon all the time.

You may already know that most of the rarest pokemon you can't breed, and that starter pokemons and the not quite so rare, are always male. By breeding one of these pokemon, such as feraligatr, or snorlax with a ditto, you will recieve an egg which will hatch in about 5000 foot steps and will hatch into the lowest evolution of the pokemon you bred

Okay, to catch the 3 legendary dogs, you have to have found (but not caught or defeated) at least one of them first. Then go to your Pokedex to find out where they are. WARNING!!! DO NOT FLY!
If you use fly there is a 99.3% chance that they will have ran to the other side of the map by the time you have landed. Also, Raikou is VERY tricky when it comes to chasing him. What he does is runs towards you, then when you get to that area, he is already back to where he started, or has jumped half way across the map. Entai is slowest and will still in an area until you get there IF you are about 30 seconds from that area. And Suicuine is almost impossible unless you use fly to a city that you can get from one side of the map to the other in about 25 minutes. REMEMBER! Don't FLY!!!

Good Luck!

First u have to save to save the director from the team rockets underground basement. Then the basement leads to the goldenrod pokemart. But when you save the director leave through through the stairs. Then you are in the pokemart basement. Go down and pick up the item it is an AMULET COIN. What it does is when you give it a pokemon to hold you get double the money when you defeat a trainer in battle. THIS IS EVEN BETTER ON THE ELITE FOUR. AND EVEN ON LANCE. He normally gives u $5000 DOLLARS BUT WITH THE AMULET COIN HE'LL GIVE U A $10000 DOLLARS.

First talk to the trainers who give you their phone number. Say yes to their question. Now fly to your house in New Bark Town. Go in & talk to your mom. She will say is it about your money. Say no. Then she will tell you want to switch to Daylight Saving Time. Say yes and she will change the clock. Try it a couple more times if it doesn't work the first time.

ok, when you defeat the elite four a lot, your pokemon will be a high level. When you have one like a level 71, it can defeat just about all the members. So once you do that, clone pokemon holding EXP. share. now make sure you have a high leveled pokemon, and 5 EXP.share's. choose 5 pokemon you want to level up fast, then give them EXP.shares. Go battle the elite four, and they will all get a lot of EXP. this is a good tip if you need a pokemon to evolve

When you first release the dogs one goes left, one goes right and one goes down. If you go left until you come to a grass patch and search you run in to one. Then go back to the tower and go down until you find a grass patch (you should end up near golden rod) and search. I found suicine here. Go back to the tower and go right until you find a grass patch and search. I found all three legendary dogs like this.

At the game sentors don't play to get coins so you can win the pokemon just buy coins, it's less expessive and you can get pikachu, lavataire, or/and polygon!

01??EDDO
replace?? w/##
01-fd
fe is glitch egg
ff is goof up glitch

USE A SCIENTIFIC CALCULATOR TO GET CODES;
ENTER POKEDEX NUMBER THAN CONVERT TO HEXADECIMAL(HEX)

Pick up the Eevee in Goldenrod city. It doesn't matter if it is male or female. Then catch a Ditto and give the Eevee and the Ditto to the Daycare man and lady.

Come back in a couple minutes and you will have an egg. It will hatch into Eevee. Do this 6 times and you will have all Eevee evolutions when they evolve.

To get Heracross and Aipom, get Headbutt from the Trainer in Ilex Forest, them use it on the little trees in Route 29, the route right next to your home town. It has to be in the afternoon, though.

Go to the day care center at Golden Rod City on route 33 and walk in to the guys house and then go through to the back in his yard. There is a little area of water here, and if use a good rod you will be able to encounter one.

Explanition:

Step 1:
Go in front of the computer in one of the two building where you start the bug catching contest.

Step 2:
Save your game.

Step 3:
Start the contest, and catch any Pokemon you like.

Step 4:
After they tell you who the winner is, go to the computer. Go to Bills PC.

Step 5:
Switch to another box, and while it says SAVING DO NOT TURN OF THE POWER, you turn it off.

Step 6:
When you turn back on, you should have the Pokemon you caught (and the prize if you won) in your party or in Bills PC. And you can do the contests again.

Step 7:
Repeat this as many times as you want to.

I found this bug, there might be other people who have found it. But credits goes to Xodac.

The easiest way to catch Entei, Raikou, and Suicune, is to do the pokemon cloning trick on a pokemon that's holding a masterball. Do it 3 times so that you have 4 masterballs. This way when you see a Legendary Dog in the wild, you can just use a maserball. This saves you a lot of time. I caught all 3 in 2 days.(You want 4 masterballs so you'll have one left over to catch Lugia or Ho-oh)


Hint: The best places to find the legendary dogs is route35, route36, route37, route38, and route39.

You need some strong batteries. Deposit 2 pokemon at daycare, and then put something on ur "up" to make your character still step up. For each step up, pokemon get 1 exp. So put something on "Up", and go sleep! You need strong batteries ^^ because if they'll end for example hour before you get up, all is lost!

I don't know if people still play this, or how this will work out for you, but this is what happened to me.
I was playing Crystal and I got the spearrow with mail or whatever it is that you're supposed to deliver. So, out of boredom I decided to clone this so I would have my own spearrow. I went to do the cloning trick, saved in front of the PC, realized I had to take the mail off to clone it so I did, and then I finished the cloning trick. I got a big block of squiggles in the end, and the box I cloned it in turned into a black hole, either deleting pokemon that went into it or making them into the missingno. I put a missingno in the daycare and it looked like a male character/starter trainer person. If you click on them/talk to them/look at their stats it'll freeze your game and you'll have to turn it off and on again.
I also got PokeRus.
Another fun fact is you can't deposit this thing. When you try to put it in the PC it disappears, as well as all the pokemon behind it (like if it's first in your party then it'll look like you have no pokemon.)
Anyone who has any results with this please email me.

When you get to the point in the game where you heal the Olivine City's gym leader's Ampharos, she tells you she'll battle you in her gym. Jasmine is the sixth gym leader. Her pokemon are:

Magnimite: lv 30
Steelix: lv 35
Magnimite: lv 30

Instead, go to Mahogany town and challenge the gym leader there. Price is the seventh gym leader. His pokemon are:

Seel: lv 27
Dewgong: Lv 29
Piloswine: lv 31

Notice that the seventh gym leader's pokemon are lower than the sixth gym leader's pokemon. You can battle the seventh gym leader before you battle the sixth, and you can even beat the eighth gym leader without beating the sixth.

The only catch is you can't enter the Pokemon League without beating all the gym leaders. Jasmine, logically, should have been the seventh gym leader and Price should have been the sixth.

when you go to the safari zone you go to a patch of grass and slightly press a direction untill you turn and it wont take up any steps

PokeRus is a Pokemon Virus that your Pokemon catch. No-one really knows how your Pokemon get it but it is commonly thought that you are more likely to get it from using body attacks such as Tackle or Slam. The chances of actually getting it are incredibly low, and those who do get it are lucky, because Pokerus actually makes your Pokemon better!

When your Pokemon levels-up, how many stat points it gains is based on its 'effort values'. Effort values are gained when Pokemon level up and are also gained from when you give your Pokemon vitamins or minerals. So when you give it a vitamin to get more stat points, it also affects it in the long term because it adds 10 to its effort values. Effort values are out of 100.

The way Pokerus helps is to give your Pokemons effort values a 'booster' so you gain more stat points when you level up. When your Pokemon has had Pokerus it cannot have it again and a little dot appears next the pokemons name in the status window. Pokerus is contagious, so you can get your whole party infected!

Pokerus will go away after 4 or 5 days, but not if you put a Pokemon in storage.

w00t!

If you're game will no longer save (you play for a while, save, turn off your gb, and when you turn it back on it says only "new game" and "option") i can offer you much assisstance OK. the save file memory is controlled by a battery inside the game cartridge. to replace the battery, first, take the hexagonal screw* out of the back of the game. remove the cover. the battery will be wrapped with yellow electrical tape. remove the battery (be careful not to separate the metal from the game chip!!!) go get yourself a new battery (i got mine at walgreens for $3.49) and reattach the battery by wrapping it in electrical tape (+ side down and attached to the uppermost metal connector). soldering works too, but why waste your time? and there you have it. you should be able to save your game
*hexagonal screw drivers aren't the most common things. i used a fine, metal tip pen to unscrew mine. the screw's not in very tight.

You can give Apricorns to the Poke Ball maker in Azalea Town to get new types of Poke Balls. Here is a list of what they're good for.

-White Apricorn: Fast Ball -- Good for catching Pokemon that try to escape from battle quickly.

-Red Apricorn: Level Ball -- If your Pokemon's level is significantly higher than the wild Pokemon's, it will be an easy catch.

-Blue Apricorn: Lure Ball -- Good for catching Water types when fishing.

-Pink Apricorn: Love Ball -- If the wild Pokemon's gender is opposite that of your Pokemon's you'll have an easier catch.

-Black Apricorn: Heavy Ball -- Big enough to catch heavy Pokemon like Snorlax.

-Green Apricorn: Friend Ball -- Pokemon caught with Friend Balls will become very attached to their trainer. Good for Chansey (if you want it to evolve into Blissey).

-Yellow Apricorn:Moon Ball -- Good for catching Pokemon that evolve with Moon Stones, like Clefairy and Jigglypuff.

this is a very easy way to randomly change the names between the pokemon in your first box

just go to the box that you want the pokemon names switched and select move pokemon w/o mail. then take the first pokemon you have in there and move it to a box, any box then while its saving turn the gameboy off there is a very short time that it saves. when you turn it on the pokemon that used to be first is last and all the nicknames should be rearanged

When raising your pokemon to Level 100 (or any other level) make sure that you train it by fighting, not by using Rare Candy's. If you raise your pokemon by fighting, it gets stronger stats. If you raise your pokemon with Rare Candy's, it's stats will not get as high than if you raised it by fighting.

Catch more than three unknown and go to the house and talk to the professor and he will give you the unknown pokedex.

At the Daycare Center south of Goldenrod City on Route 33, you can give a male Pokemon and a female Pokemon to the keepers to breed new Pokemon.
Breed two Pikachus to get Pichu.
Breed two Electabuzzes and you get Elekid.
Breed two Clefairies and you get Cleffa.
Breed two Jigglypuffs and you get Igglybuff.
Breed two Magmars and you get Magby.
Breed a Venonat with a Pinsir to get Pinsir.
Breed a Hitmonchan or Hitmonlee with a Ditto to get Tyrogue.
Breed a Clefairy with a Snubbull to get another Snubbul.

WARNING: This trick may damage your Pokemon Gold/Silver Cartridge, or result in the loss/corruption of save data!
HOW TO CLONE POKEMON ON GOLD AND SILVER 9 EASY STEPS

1. GET 6 POKEMON

2. GET TO ANY POKEMON CENTER

3. WALK OVER TO THE COMPUTER

4. CHANGE YOUR POKEBOX

5. WALK AWAY AND GIVE THE 5 POKEMON YOU WANT TO CLONE AN ITEM
(AT LEAST 2 A POKEBALL)

6. SAVE YOUR GAME

7. DEPOSIT THOSE 5 POKEMON INTO THE OPENED POKEBOX

8. GO TO CHANGE BOX

9. WHEN YOUR GAMEBOY SCREEN SAYS:
SAVING...DON'T SHUT OFF THE POWER
TURN YOUR GAMEBOY OFF THEN TURN IT ON AND CHECK YOUR POKEMON AND THEN GO TO THE PC AND YOU'LL HAVE A POKEMON AND THE ITEM

At the title screen press up+B+select or start

If you go to the point outside the cave in the Unown Ruins, a boy stands. He has a Smeargle. Go to your radio after you beat him. Move around in it until you hear this weird music. It's kind of eerie.

This cheat has not been done by anyone else other than me. I personally discovered this by myself and therefor only give credit to myself.

As we all know, you can catch a Missingno in red/blue versions. Well, after you have reached the 4th gym of crystal/gold/silver, you can trade Pokemon with the 1st generation games. All you need to do is catch a lvl 1 Missingno using the duplication hack in the red/blue versions. Your game sprites might get messed up but that will be fixed after what you do later. Missingno has it's own type called "fly". Well, if you use the HM fly (sky attack also works) on it, it should be able to learn it. This is where you abuse the glitch. After teaching Missingno fly or any other flying moves you have, give it a rare candy. If you ever messed around with Missingno you know that after you give it a rare candy it mysteriously evolves into a Kanghaskan. Now all you have to do is to transfer the Pokemon from your old game to Crystal/Gold/Silver using two game boys and a link cable. After that, your Kanghaskan should be able to use fly and moves such as Sky Attack. Fly also works as a transport to get from one city to another. Do this at your own risk but keep in mind that this is something cool to show your friends.

There are Four Truly Evil Pokémon lurking inside your game's programming... only you don't know it yet. Here's an easy, step-by-step explanation on how to find the Evil Four. Step 1: Get a GameShark. Step 2: Enter this code: 01??EDDO. Replace ?? with the following numbers. FC, FD, FE, and FF. Step 3: Go to a place where you can find wild Pokémon. Step 3 1/2: You will find three Glitch Pokémon with the name ??????. The fourth Glitch is a wild EGG. Step 3 3/4: Their numbers are 252, 253, 254, and 255. Good luck with catching them... you'l need it...

bulbasaur-0101edd0
chamander-0104edd0
squirtle-0107edd0
celebi-01fbedd0
mewtwo-0196edd0
mew-0197edd0

To retreive all 3 johto starters (chikorita, totdile, cyndaquil) is a mere trick wich requires no outward trading or game sharking. Here is how its done.

Step 1: Start A NEW GAME

Scary as it may sound, this is how you achieve the duty. Once you start the new game, save it before you enter Prof. Elm's lab for the first time.

Step (a): Picking your starter

Go in, talk to the good professor, and get your pokemon of choice. simple. Just remember this. DO NOT SAVE.

Step (b): The mission
Head north to Mr. Pokemon's house(south of violet city) and collect the egg. Head back to New Bark Town where you will fight your jerk of a rival for the first time, so it is reccomended to train your starter a bit. After you beat him(or lose, which ever one) head to Professor Elm's lab. After a bit of talking with the 5-0, show the professor your egg. This will begin your journey. Just remember this, DO NOT SAVE. This entire process will take 10-25 minutes.

Step (c): The cloning
Talk to Professor Elm's assistant. He will give you 5 pokeballs. As you may know the cloning trick does not work with out another pokemon in your party, so go out and catch 1 pokemon(it doesnt really matter) and have it in your team. Deposit your starter, and do the cloning trick. Remember, that if you save, you'll be wasting your time.

Step (d): Restarting
Once you shut off your game and restart it. YOu'll notice that your right back to your first save point in new bark town if you did this right. Grab a different starter than the one you first choose. Repeat steps (a) through (d) for this starter.

---The Final Starter---
Once you begin the third attempt, you can save when ever you want. Once you reach the next town, you may access the PC and withdraw the other 2 starters. Make sure you save. You don't want to do that again.

---Notes---
1.) Once you retrieve your pokedex from Prof. Oak, You will only have the data of the starter you choose in that file. Say if you cloned Chikorita and Totodile, although you may have them in your party, their data wont be registered in the pokedex but you will have cyndaquil's data for some odd reason.
Although, once you evolve the 2 unregistered pokemon(i.e. Chiko and toto) their evolved forms (croconaw/Feraligatr and Bayleef/Megainium) will be logged into the pokedex.

2.)All three starters will have the same trainer IDs. For example. If your file's Trainer ID is 19283, Chikorita, Totodile and Cyndaquil's ID will be that. Therefore theres no worry if you level any of them up past your current Badge.

Hope this helps you guys.

Go to the northern part of National Park and to the right of the lady holding the pouch there is an invisible break in the fence (the fence is visible in this part, you can just pass through it). Around the perimeter of the park you'll find dig and another random item.

when you play your game your MOM askes if you want to save money say yes and after earning some money she will call and say either i bought you an item with your money sorry or i found the cutest doll while shopping its in your room. if she said she bought you a doll go to your room and click on your pc go to decorations and click ortements and there will be a doll name like CLEFAIRY DOLL or CHARMANDER DOLL and when you click on a doll it will ask left or right if you click left/right then it will be set up on your room table. try it, it works. your mom can also buy you stones.

In basement of Dark Cave there is a Lapras that appears every Monday. Catch the rare beast, for it's the only one in the game. It appears every Monday, so catch as many as you want.

This is a long process but makes your critters stronger,Take a high Lvl,15 and up,and go to newbark town,gain etleast five lvls from the lvl 2's,and 3's then go to the pokemon center,save your file infrony of the computer,then open you box for bill and put your training pokemon in the box,change box'es and during when it says"saving do not turn of power"!turn the game off!then turn it back on realy quick,then open the box that u were going to go to and open it up and the cloned pokemon will be cloned and strong then most other pokemon!

go to a pokemon center, go to the computer, save your game(very important in case it screws up), deposit the pokemon you want to clone with or without an item you want to clone, change the box, but when it says SAVING DON'T TURN OFF THE POWER turn it off and then turn it back on and you should have the pokemon in your party and your box.

If you don't move and slighty tap the D-pad, so you face different directions, you'll be able to get all the availabe ones from there!

Press Start + Select + A + B while the credits are displayed.

As you may know, Larvitar can evolve into the exremely powerful Tyranitar when it reaches level 55. This may seen hard to achieve, but there is a faster way to get Larvitar powered up.

Catch a Larvitar in Mt. Silver

Take it to the Day Care in Goldenrod City

Now, every step you take is one experience point for your Larvitar while it's in the Day Care.

Fly to Celadon City
Go to the top of the bike path

Ride all the way down the extremely long path, which is downhill all the way and you get to the bottom really fast. You should end up with about 600 steps already when you reach the bottom. Keep flying back to Celadon and riding down the hill and your Larvitar will grow faster.

Ok, once you have Surf and a few Lv. 20 Pokemon, go back to the Ruins of Alph, use Surf on the pond left of the Kabuto Ruins, there will be only Quagsire & Woopers there.
Note that you can still use a Rod to get Pokemon like Goldeen and Magikarp still.
