Get all starters
To get all the starters (Bulbasaur,Charmander, and Squirtle), you will need two Game Boy Advances and another Pokemon GBA game. Start with Bulbasaur, then trade it to your other Pokemon game. After that, start a new game. Start with Charmander and trade it. Then, start another new game and start with Squirtle. Keep Squirtle and catch two Pokemon that you do not want. Trade them for the other two starters you traded to your other Pokemon game. You will now have all three starters.
To get the ancient Pokemon Aerodactyl, go to the house to the right of the Museum in Pewter City. Note: You must have Cut. Talk to the scientist and he will give you the Old Amber. Take it to the Lab on Cinnabar Island and let the scientist bring it back to life. It will be at level 5.
Surf south from Fuschia until you hit a barrier. Then, Surf west to the Seafoam Islands. When you see boulders, push them into the pits to reach the legendary bird Articuno.
It is possible to get Deoxys at an island in which you solve a simple puzzle.
To get Deoxys, go to Island 9 and push the triangle forward. Deoxys will appear.
To obtain Deoxys, you must travel to Island 9. To do this, you need to obtain the Aurora Ticket, which can only obtained through a Nintendo Event, such as Pokemon Rocks America 2004. Bring your Pokemon Fire Red or Leaf Green cartridge to any of the events in Atlanta, Minneapolis, or Seattle to receive the Aurora Ticket. The same goes for obtaining Lugia, Ho-Oh (both on Island 8, requiring Mystery Pass); and Celebi and Mew (details unknown). Note: Ho-Oh can also be obtained via a link to Pokemon Coliseum.
Note: In the Pokemon Fire Red, you will get the attack version of Deoxys.
Defeat the Elite Four, then go to the Cerulean City Cave. Mewtwo will be there. You will need HM6 Rock Smash and HM3 Surf.
To get Moltres you need HM4 Strength, HM6 Rock Smash, and HM3 Surf. Go to One Island, and all the way to the right until you reach water. Surf to the north and you will see land. Continue to go north until you hit water again. Then, Surf north again until you reach land. Go up and move the boulders. Continue to go up and you will enter Mt. Ember. Pass the mountain and you will see more boulders up ahead. Move them and you will encounter Moltres, the Legendary Fire Bird Pokemon.
To catch a Zapdos, go to the Pokemon Center beside the Rock Cave. From the Pokemon Center, go up until you reach water. Surf to the Power Plant and go inside. Find your way around, and at the end you will find Zapdos, the Thunder type Legendary Bird.
The legendary dog that you get in the game depends on your starter.
Charmander: Suicune (Water)
Squirtle: Raikou (Thunder)
Bulbasaur: Entei (Fire)
To get all three Legendary Dogs, get together with two friends before any of you start the game. Have one player get Charmander, another get Squirtle, and the other get Bulbasaur. Each of you will get one of the legendary dogs: Charmander, Suicune; Squirtle, Raikou; and Bulbasaur, Entei. Once each of you has their own dog, trade one dog for another. For example, player one's Suicune for player two's Entei; player three's Raikou for player one's Entei; and Player three's Raikou for player two's Suicune.
To get your first Pokemon from the Johto Region, defeat the Elite Four. Go to Island 3, then go in the tunnel. Talk to the man and he will give you a Nugget. Go out the door, and there will be a small patch of grass. Walk around in it, and you will find your first Johto Pokemon.
Note: This trick will only work on Pokemon that have a gender. Either male or female will do. For example, if you want a friend's Charizard but you do not want to trade a level 100 male Venusaur for it, catch a Ditto on Route 13 to 15. Take both your Venusaur and Ditto to 4 Island to the old couple and breed them. The next morning you will have a Bulbasaur egg ready to trade. This can be used to get all the evolutions of Evee. Note: This trick will not work on Mewtwo or most of the legendary Pokemon.
Use the following trick to easily reproduce rare Pokemon, such as Charizard, Lapras, etc. Capture a Ditto in Pokemon Fire Red or Leaf Green. These can be found in the cave at Cerulean. Transfer your Ditto to Pokemon Sapphire or Ruby, then take it to the Daycare couple in Mauville and leave it there. The quickest way to get an egg is to cycle back and forth a few times in front of the Daycare Center until the old man comes out of the gate. The egg he gives you will hatch into the first evolution of whatever Pokemon you put into the daycare. For example, a Charizard will give you a Charmander. Trade with friends to get the other starters, breed an egg, then trade back. The hatched Pokemon will have you as the original trainer.Some Pokemon will not breed in this way, even though they have a gender (such as Latios and Latias).
There are four new moves not found in earlier Pokemon games:
Blast Burn (Fire): Power: 120, Accuracy: 100, leaves the user immobile the next turn. Black Belt
Hydro Cannon (Water): Power: 120, Accuracy: 100, leaves the user immobile the next turn.
Frenzy Plant (Grass): Power: 120, Accuracy: 100, leaves the user immobile the next turn.
Volt Tackle (Thunder): Power: 120, Accuracy:100, slightly hurts the user.
After you get to One Island, travel up the path called Kindle Road and go towards the volcano. Along this route, you will encounter several trainers with Fighting-type Pokemon. Have your Pokemon use Thief to steal a Black Belt from each of the Pokemon. After you have a Black Belt, take it off your Pokemon and use the VS Seeker to fight the opponent again. Steal another Black Belt from his other Pokemon. Every Fighting-type on this route is equipped with a Black Belt, which boosts the power of all Fighting-type moves.
Go to the last person (Team Rocket member) on Nugget Bridge. Lose to that person after you get the Nugget. Repeat this until you have the desired number of Nuggets. Note: If you save the your game after defeating him, you will no longer be able to do this.
To get more Rare Candies, look for some Meowths. You are 30% likely to get one.
Repel and Super Repel
Repel and Super Repel will keep all wild Pokemon of a lower level than the first Pokemon in your party from attacking. However, if the wild Pokemon is of the same level or higher, it will attack. Due to the decreased amount of Pokemon to fight, you will have less random encounters. To exploit the use of this, go to a cave with high level Pokemon such as at Victory Road or Union Cave. Use the Repel once inside. Find a boxed-in type of corner and tap the D-Pad gently towards a wall. If done correctly, you will not hear a bumping sound. Doing this should not reduce the number of steps remaining on you Repel counter, because the Repel only counts movement that causes the character to take a step not turning. Just turn into a wall to make it easier for beginners. This trick is useful because you are always facing a Pokemon that is of equal or greater level, allowing you to get levels much faster than usual.
Follow through Viridian Forest, go to Brock (the first gym leader), and defeat him. Brock has three Pokemon: Geodude level12, Onix level 14, and Geodude level 11. Then, go to the path that leads to Mount Moon's base. Try to go past the man standing slightly past the entrance. He should stop you. He is Professor Oak's assistant. After talking to him, he will give you the Running Shoes.
Your aide will give you the Running Shoes after the first gym.
Go to the Naval Rock Island (if you have the Mystic Ticket), and to the location where Ho-oh confronted you. Use the Itemfinder and it will automatically dig up the Sacred Ash, just like the Macho Brace at Viridian Gym after Giovanni left; and the Top from Pokemon Tower after Mr. Fugi left.
Celedon City: Easy slot machine wins
Use the slot machine at Celdadon City that is at the top in the row you face when you enter. It seems to be easier to get triple sevens if you can time it correctly.
When you first go in, just go straight until you hit a wall. If you want to get Lugia first, go to the right. If you want Ho-oh first, go to the left. It really does not matter, because you can get both. They will both appear at level 70.
An easy way to defeat Giovanni in all battles is to use a Water Pokemon with Surf on all his Pokemon.
Defeating the Elite Four
After you defeat the Elite Four and you give Celio the Ruby and Sapphire Plate (on the seven islands), you can re-challenge the Elite Four. Their Pokemon are now changed and become much more stronger than the first time you challenged them. Here are the combinations:
Lorelei: Dewgong level 64, Cloyster level 63, Piloswine level 64 (replaced Slowbro), Jynx, and Lapras level 66.
Bruno: Steelix level 63, Steelix level 66, Hitmonchan and Hitmonlee level 65, Machamp level 68 (his 2 Onix have evolved).
Agatha: Gengar level 66, Crobat level 66, Arbok level 68, Misdreavus level 65 (replaced Haunter), Gengar level 70 (her Golbat has evolved).
Lance: Gyarados level 68, Kingdra level 66, Aerodactyl level 70, Dragonite level 66, Dragonite level 72 (one of his Dragonair evolved, and the other was replaced by Kingdra).
Rival: Heracross level 71, Alakazam level 69, Tyranitar level 72, and depending on who you chose at the start;
If you have Bulbasaur: Gyarados level 71, Exeggutor level 73, Charizard level 75.
If you have Squirtle: Gyarados level 73, Arcanine level 71, Venusaur level 75.
If you have Charmander:Exeggutor level 73, Arcanine level 71, Blastoise level 75.
For Lorelei, you need a level 60 or higher Electric type with like Thunder or Thunderbolt. Watch out; her Piloswine is also a Ground type and is immune to Electricity. Use Water type or Fighting. Bruno is very easy to defeat if you have a very good Water type for the Steelixes and a level 53 or higher Alakazam or Kadabra; or a very strong Psychic type. Agatha is tough because of her speedy Pokemon. If you have an Alakazam and it is at least level 58 or higher, then you will have no problems. If not, try using a strong Steel type. Lance is annoying because he now has a Kingdra, which is not really affected by Ice types because of its Water type. Use a tough Electric type. The rest are easily dispatched by an Ice Beam or Blizzard. Your Rival is difficult. His Heracross has good speed, but flying attacks kill it because of his double weakness. His Alakazam can be defeated by a good Hyper Beam or even Strength because it lacks defense (not special defense). His Exeggutor or Gyarados are poor, but his Arcanine is strong -- do not underestimate him. The real problems are his Tyrannitar and the starter. Tyrannitar is good in every stat, and he is a Dark type which makes him unaffected by Psychic types. He is also a Rock type, so use Razor Leaf or Surf. The starter is tough, and is not easily dispatched.
Get to One Island
To Get to One Island, defeat the Cinnabar Island Gym Leader, Blaine. When you come out, Bill will take you to One Island and give you the Tri-Pass. This will allow you to return at any time by taking the Pass to the boat dock in Vermilion City.
Get to Saffron City
Unlike in Pokemon Red and Blue, to get into Saffron City, you do not give the guard a Fresh Water. You must go to Celadon City then enter the Game Freak building. Inside is an old woman with Pokemon around her It is the building above the Game Corner. Once there, talk to the old lady. She gives you some "tea", which you can then give to the guard. All the guards will now let you go into Saffron City. Remember to get the powerful TM 29 Psychic in Mr. Psychic's house (in the bottom far left house of the city). Also, your Pokemon should at least level 38 or higher when attempting to battle Sabrina.
Get to Saffron City earlier
This trick requires two Game Boy Advances, a link cable, a Pokemon Ruby or Sapphire game with a "Fresh Water" in the pack, and a Pokemon Fire Red or Leaf Green game that is completed and able to trade with Pokemon Ruby or Sapphire. Also, you will need another Pokemon Fire Red or Leaf Green cartridge. Give a Pokemon a Fresh Water. Trade the Pokemon from Pokemon Ruby or Sapphire to the completed Pokemon Fire Red or Leaf Green game. Take the Fresh Water and attach it to a Pokemon not from Pokemon Ruby or Sapphire. Trade it to the other Pokemon Fire Red or Leaf Green game. Give the Fresh Water to the guard. You can now access Saffron City easier. You can also do the same thing without the Pokemon Ruby or Sapphire cartrigde. Also, it works better when you have the completed cartridge and your friend has the unfinished game.
Navigate through the lost cave on Island 5
Move right, up, down, down, right, left, down, right, up and you will arrive at your destination. Note: You can go different ways, but you will end up either finding an item or going back to the start.
Get to Sabrina without battling any trainers
This is a long process, but it is the easiest way. Go into the first square, then go up, down, down, up, down, up, up, down, down, up, up, up, down, then down and you will be there.
Unlimited Safari Zone time
Enter the Safari Zone, then walk into an area and stop in the grass Then, tap the D-Pad, but do not move You will find the Pokemon in that area without wasting steps.
Find one location in the Safari Zone that suits you. Then, just rotate in place. Random Pokemon should you attack you every few rotations.
To get easy money, use a Meowth with the Pay Day attack in wild or trainer battles.
Determining Pokemon's feelings towards you
When you use an item on one of your Pokemon outside of a battle, such as a Potion, the Pokemon will either move closer or away from you in the short intermission sequence. How far the Pokemon moves depends on how much it likes you. If it does not move at all, it feels neutral.
Answers to Blaine's questions
The answers, in order are: yes, no, no, no, yes, and no.
Trainer name comment
At the Pokemon Trainer Fan Club in Saffron City, the blonde man in the back will mention the last person you battled in real life. For example, if you battle a friend who named their character "Dusty", he will say, "Dusty's cool, huh? I love the way he talks. I'd really relish a chance to meet him in person once."
More than one attempt when catching a Legendary Pokemon
When you are close to a Legendary Pokemon and want to catch it, save the game just before you battle it. If you accidentally make it faint, Just reset the game and try again.
