Duplicate Pokemon

You need a link cable, 2 pokemon games, and 2 gameboys for this trick. On 1 gameboy, have a strong pokemon that you both want. On the other, have a weak pokemon that your willing to give up for the other one. Enter Trade mode and trade pokemon. On gameboy 1 (the one with the good pokemon), turn off the gameboy right before it says ''Trade Complete!''. The 2nd GB should say ''Trade Complete!'' on it. If done correctly, the bad pokemon on GB 2 should be deleted and replaced with the good pokemon. The good pokemon on GB 1 should still be there.

Duplicate items

To get WELL 99 of an item, put the item you want duplicated in the sixth item slot. Make sure you have the Fly HM, then Fly to Viridian City. Talk to the old man that stopped you in the begining of the game( kind of to the north) When he asks if you are in a hurry, say no and watch him catch a weedle.

Then Fly to Cinnabar Island, and use the SURF HM. Surf along the right COAST, Not in the water, if you surf in the water it won't work.

Now, use SURF until you run into a Pokemon called ''M'', ''Missingno.'', Or a Pokemon over level 100 Once you see one of those, kill it or just simply run away. DON'T CATCH THE M OR MISSINGNO. AS IT WILL RUIN YOUR GAME!!!

When fighting a high level M if you have a slow pokemon and it attacks you are screwed, as it has a VERY high attack, you can beat him by simply using a quick attack.

after you win/run look at your sixth item it should look VERY weird with wird symbols and such, don't worry all it means is you have over 99 once you use it up alot it will stop using symbols and once the supply gets back to 99 it will show up as ''99''

Invisible PC

In the Celadon Hotel, you will notice that the graphics and internal structure of the building are much the same as that of a Pokemon Center. There is even a PC here, although it is invisible: it is in the same spot as a normal Pokemon Center along the east wall. The same is also true of some of the Rest Houses in the Safari Zone that have Pokemon Center-like design. You can interact with this PC as normal to insert and withdraw your Pokemon.

However, take note that if saving is done your actual location will not be saved. This can be used to some degree for sequence-breaking glitches and speed-running by saving in one area by changing PC boxes, then reloading the file. You'll have all your progress done as before, but your location will be the same the file before this save. For example, you can save normally in Pallet Town, then do so in the Celadon Hotel by using its invisible PC. When you reload, you'll have met all of the progress you did between Pallet Town and the Celadon Hotel but will be back in Pallet Town.

Catch Safari Zone Pokemon w/o Safari Balls

First go into the Safari Zone (SZ). Go into the area with the pokemon that you want(e.g. Scyther). After you're there, fly to Cinnibar Islands. Surf up & down the right coast, and eventually SZ pokemon will battle you there. If you need other SZ pokemon, just keep swimming up & down the coast. The effect of this glitch doesn't affect your saved game. If you get tired of swimming, don't get out of the water: instead, save right where you are. When you resume your journey, the SZ glitch will still be in effect. This glitch works with any area, not just the SZ.

Glitch City

Glitch City is a weird glitchy town that you can unlock (and get to) by doing the following in this order:
-Go to the Safari Zone (in Fuchia City)
-Enter Safari Zone (pay the 500 bucks)
-Go out of the Safari Zone and when the guy asks you if you want to leave, say ''No''
-Repeat the last step
-Save your game when you are in the Safari Zone, and turn it off
-Turn the game back on and leave the Safari Zone (the guy shouldn't ask you if you want to leave)
-Go to Cinibar Island and surf half on land and half on water, DO this until a message pops up- ''PA-Ding-Dong, Time's Up! Your Safari game is over!''
- You will then be transported back to the Safari Zone
-Exit the Safari Zone building and you will be in Glitch Town
Congrats you did it!

Moonstone evolution without moonstones

If you have a pokémon that needs a moonstone to evolve, you can cause it to evolve though normal battling. First make sure that the pokémon needing the moonstone to evolve is in the lead position before going into a battle. Once the battle has started, switch that pokémon with another that knows the move "Mimic". Have this pokémon continually use Mimic to defeat your opponent. If the shared experience gained from battle is enough to level up your moonstone needing pokémon, it should evolve as if a moonstone was just used on it.

Bypass Cycling Road Guard

To get onto the Cycling Road without needing a Bicycle, simply hold Left while the guard warns you that you must have the Bicycle to enter Cycling Road. (If you already obtained the Bicycle, this still works if the Bicycle is in the PC.) In doing so, you will bypass the guard; if you continue onto Cycling Road, you'll still ride a bike.

The Old Man Glitch

This glitch requires you to have the Badges allowing the use of Fly and Surf, and Pokemon that can use these moves. You must also be able to reach Fuschia City or Cinnabar Island. First, head to Viridian City and speak with the old man near Route 2 who will teach you to catch Pokemon; view his tutorial. After doing so, Fly to Fuschia or Cinnabar and Surf to the Seafoam Islands. Once there, Surf on the coastline of the islands. As you Surf, you may encounter a number of odd Pokemon. These Pokemon will differ, depending on the name you used as that of your Trainer. For example, the name "DANIEL" can make Snorlax or Electrode appear, among others. However, a common characteristic of them is that they are often above Level 100 and thus very powerful: if you manage to catch one somehow, you essentially have a very powerful Pokemon, and can even level it up further, as high as Level 255. (Note that some Pokemon may evolve into glitch Pokemon because of this.) That is the first benefit of this simple glitch. Most people, regardless of name, should be able to encounter one of two Pokemon: Missingno. or 'M, both of which are glitch Pokemon. These two have special effects on the item in the sixth slot of your item bag, but that effect depends on whether you catch or defeat the Pokemon. If you defeat the Pokemon (or otherwise just do not catch it), the item in your Bag's sixth slot will be changed so that you have 128 of it; if you catch it, you will have 255 of it. (This is assuming you use an item that you can have multiple ones of.) This is very useful for mass-cloning valuable items, such as Master Balls, Rare Candies, or PP Maxes, or to clone TMs to sell for obscene amounts of money.

Hyper Beam Recharge Perpetuation

This glitch can be executed on Pokemon who have used Hyper Beam and are Frozen during their recharging turn. If you use Haze on this Pokemon, they will thaw out - however, they will always be recharging from their Hyper Beam, meaning they and their Trainer can do nothing until you defeat it. You can capitalize on this with healing across the party, massive stat boosts, and inevitably killing the Pokemon.

Invulnerability

This glitch is executed when a Pokemon using Fly or Dig becomes Paralyzed before the turn on which they attack: it is only done by being Paralyzed when you are high up in the air when using Fly. If such occurs, you will be invulnerable. This glitch lasts until your Pokemon uses Fly or Dig again and is successful in doing so, you switch Pokemon, the Pokemon faints, or the battle ends.

Boost Leech Seed's Absorption

Leech Seed is a move well-known for absorbing 1/16 of the target's HP and healing the user of the move by the same amount. However, you can actually boost this damage through the unintended effects of Toxic. When you use Toxic to Badly Poison a foe, and then use Leech Seed on them, Leech Seed's damage will also increment: thus, you regain 1/16, then 1/8, then 3/16, then 1/4, and so on, of your HP. Toxic will also be taking effect in this time, dealing the same amount of damage. In other words, you not only regain tons of HP, but also double the damage of Toxic, from one point of view.

Skip the Pewter City Gym

This obviously can only be done before beating Brock in Pewter City. At the east end of town is a kid who will take you to the Pewter Gym if you have not beaten him yet. One tile before walking into his line of sight, open the pause menu and hover the cursor over "SAVE". Now, exit the menu with B, then walk in front of the kid. Throughout the conversation that follows, continue pressing B to advance the text. Immediately after the texts ends, press Start, then save the game. Let the kid walk you to the Pewter Gym, then enter the pause menu and reset the console.

After the game reloads, you'll be taken to the Gym again. This time, continue back to Route 3's entrance. This time, the kid won't be there. However, be sure hug the north side of the rock wall as you go east: you'll trigger the conversations again if you do not.

Note, too, that you must beat the Pewter Gym eventually to beat the game. This is best used for those who intend to go back later with a better Pokemon party, such as those who started with Charmander.

Evolve Pokemon without Stones

To execute this glitch properly, you need a Pokemon who evolves via a Stone (Fire Stone, Leaf Stone, Moon Stone, Thunderstone). This only works with Pokemon whose internal ID number is equal to that of the item used to evolve it. So long as you send out such a Pokemon as your lead in the battle, and defeat the foe with a different Pokemon, this can be done. What Pokemon you switch to is important, as noted later.

First, send out the Stone-needing Pokemon as your lead. On the first turn, switch him out for the Pokemon that you do not want to evolve: doesn't matter which. When the Pokemon beats your foe, if the shared EXP. makes the Stone-needing Pokemon level-up, the same Pokemon will evolve.

This list describes who you must switch to for this to work:

- If you need a Thunderstone evolution, win the battle with Growlithe.
- If you need a Moon Stone evolution, win the battle with Exeggutor.
- If you need a Water Stone evolution, win the battle with Onix.
- If you need a Leaf Stone evolution, win the battle with Psyduck.
- If you need a Fire Stone evolution, you must win the battle with a Missingno. whose internal decimal index number is 32, which is impossible to get without the use of other glitches.

Walk Through Walls

First, begin this by going to the Safari Zone in Fuschia. Arrive there with only one Pokemon in your party, and this Pokemon must be Poisoned (PSN). Enter the Safari Zone gatehouse and pay $500 to begin playing. Immediately upon entrance, go back into the gatehouse and, when asked if you wish to leave, say "No.". Then save the game and reset the console, then reload your save file.

When you reload, begin counting every single step you take - this is very crucial to this glitch. When you reload, go into the Safari Zone building and opt to not play the game. Walk around now and be sure to do so near a ledge. Count until you have taken 499 steps and land the 499th step next to the ledge. (You can also count for 124 flashes of the screen, due to Poisoning, and 3 additional steps.) Heal your Pokemon periodically as well so that they do not faint (keeping the Poison active).

On the 500th step, do it so that you walk off the aforementioned ledge for it, thereby ending your Safari Game from earlier in mid-air. You will return into the Safari Zone gatehouse. Do not try leaving through the exit or your game will crash! This is why I mentioned keeping Poison active: you have to have your Poisoned Pokemon - your lone Pokemon in the party - faint by walking around due to Poison. You will then return to the last-used Pokemon Center, your Pokemon fully healed - however, there's a key difference in that you now can walk through walls and across water - basically anywhere you wish! The effects of this glitch will last until you enter a battle or speak with an NPC or enter a building.

Alter Toxic Damage

Normally when under the effects of Toxic ("Bad Poisoning"), your Pokemon takes incrementing amounts of damage: 1/16, 1/8, 3/16, and so on, of their max HP. You can negate this by switching out; when the Pokemon returns, it will only be taking a flat 1/8 damage like regular Poisoning.

Contributed by: KeyBlade999 

Negate Burn/Paralysis Stat Losses

Normally, when Burned, a Pokemon's Attack stat is halved, and when Paralyzed their Speed is halved. However, if you use Swords Dance (if Burned) or Agility (if Paralyzed), the stat loss is negated. For example, under the intended mechanics, Swords Dance and Burn would return you to normal damage output, but it actually doubles your damage output. The same is true for Speed, Paralysis, and Agility.

Contributed by: KeyBlade999 

Struggle Glitch

Normally in Pokemon, the move Struggle (used when a Pokemon is at 0 PP for all moves) is intended to be a typeless move. However, in these games it is mistakenly coded as a Normal-type move. This means that you can use a Ghost-type Pokemon against them and easily win as they won't be able to hurt you.

Contributed by: KeyBlade999 

Stat Boosting Errors

During the game, you will find that several Gym Badges actually boost your stats, like Attack, specifically with a multiplier of 1.125x; similarly, Burn halves Attack and Paralysis quarters Speed. While not intended to be applied multiple times to the same stat, they can be by affecting other stats. (For example, to stack Attack boosts from the BoulderBadge, get hit by Tail Whip, which affects Defense.) The multipliers get reapplied. You can use this to tank hits from Pokemon that use the moves; an example would be taking three Tail Whips, resulting in a 42.4% boost in Attack from the BoulderBadge. You can also use this to affect the opponent's stats; for example, if you Burn them, then hit them with Tail Whip, their Attack is halved a second time! Note, however, that directly affecting the stat you want to stack boosts/losses on - for example, using Growl on a Burned Pokemon, or using Belly Drum while stacking Attack boosts - will nullify the stacking, returning the values to their intended quantities.

Further, when a Pokemon raises its own stat stages, modifiers due to Paralysis or Burn are applied to the opposing Pokemon even though they don't possess them. For example, if your Pokemon is Burned and uses Double Team to boost evasion, the opponent's Attack stat gets halved, even though they are not burned.

Contributed by: KeyBlade999 

Level-Based Damage Boost

For reasons unknown, if your Pokemon has a Level that ends in 0, 3, 5, or 8, their damage will be boosted by approximately 3%. Thus, it is possible for you to have Pokemon with the same Attack stat, but because one is Level 98 and the other is Level 99 with slightly lower DVs, the Level 98 one can deal the same or more damage.

X Accuracy Trick

Unlike later games in the Pokemon series, in this game X Accuracy will make every move you use - until you switch out or are KO'ed - 100% likely to hit, no matter the nature of the move. Even those that are one-hit KO moves like Horn Drill, whose accuracy calculation are special, are 100% likely to hit, so it becomes easy to spam Horn Drill, Guillotine, etc., after the use of an X Accuracy!

Vending Machine Glitch

Atop the Celadon Dept. Store are several Vending Machines. You can buy Fresh Water, Soda Pop, and Lemonade from them. There is a glitch involving the costs of these items - if you can afford the Fresh Water ($200), but neither of the other two ($300 & $350), you can still buy the latter two items. Your money will deplete to zero afterwards.

Drain Move Substitute Glitch

In the Japanese releases of Pokemon Red, Blue, Green, and Yellow, as well as all versions of Pokemon Gold, Silver, and Crystal, there is a glitch involving Substitute - no matter the accuracy of the move, if it is a move that absorbs HP (e.g. Absorb, Giga Drain, Mega Drain), the move will have a 100% chance to miss!

Surfing Glitch (Red, Blue & Green JP-only)

Unlike in Yellow Version and the localizations of the games, in the Japanese Red, Blue, and Green, you are capable of Surfing starting from the north tile of cliffsides. This is most helpful in the Seafoam Islands, enabling you to find Articuno and bypass the high-speed currents without dealing with the annoying boulder puzzle involved.

Repeat In-Game Trades (JP-only)

On the Japanese releases of Pokemon Red, Blue, and Green, you can repeat the in-game trades normally only doable once. Before you begin the trade, go into your bag, hover over an item, and press Select. Exit out of the menu and begin the trade: while in your party menu, swap the Pokemon you intend to trade with another in the order, then trade it. After receiving the Pokemon from the trade you'll find yourself able to execute it again; you can execute this as many times as desired.

PP Pokemon Morphing (JP only)

This only works in the Japanese Red, Blue, and Green. You need at least two Pokemon and 16 items.

Put a Pokemon with no HM moves into slot two of your party; this Pokemon preferably is worthless since it'll be transformed by the end. In slot one, put a Pokemon that has one of its moves' current PP matching the ID of your desired Pokemon (such as 21 PP remaining for Mew). Enter your Bag and press Select on the 16th item. Press B twice to exit, then enter battle. Press Select again on the move with the desired PP, and end the battle. Go to the Daycare and drop off and withdraw the second Pokemon in your party; on its return it'll be of the same species as the PP of the swapped move!

Beat the Game in 0:00

First, assure no save file exists on your game; if it does, hold Up, Select, and B at the title screen and clear the file. Start a new game and do the usual introduction, but choose "ASH" for your name and "BLUE" for your rival's. When given control, walk downstairs in your house to the tile north of the eastern tile of the entrance mat. Open the menu and then save the game. When you select "YES", very quickly thereafter (the timing can take several tries), turn off the console mid-save. (The timing is between the text box with "YES"/"NO" disappearing and the save confirmation message changing.)

If done right, you can access your file and go into the Pokemon menu, but it's blank and extended beyond 6 Pokemon. Grab a Pokemon between slots 1-9 (those immediately on-screen) and swap it with slot 10's Pokemon. Take slot 11 and switch it with slot 9. Go to your Items menu next, and hold Down until the cursor stops flashing. Hit A and glitch the menu, then hit Down, A, Down, A in that order. Now look down the list for a Master Ball. Go down one more item and press Select. Scroll down until you see another Master Ball, and press Select to swap it with the item you grabbed. Now, toss 68 of that item. Exit the menu and then exit your house to walk straight into the Hall of Fame! You'll get the game completion scene as normal, and often have more than 150 Pokemon in your Pokedex!

X Accuracy Trick

Unlike later games in the Pokemon series, in this game X Accuracy will make every move you use - until you switch out or are KO'ed - 100% likely to hit, no matter the nature of the move. Even those that are one-hit KO moves like Horn Drill, whose accuracy calculation are special, are 100% likely to hit, so it becomes easy to spam Horn Drill, Guillotine, etc., after the use of an X Accuracy!

Vending Machine Glitch

Atop the Celadon Dept. Store are several Vending Machines. You can buy Fresh Water, Soda Pop, and Lemonade from them. There is a glitch involving the costs of these items - if you can afford the Fresh Water ($200), but neither of the other two ($300 & $350), you can still buy the latter two items. Your money will deplete to zero afterwards.

Drain Move Substitute Glitch

In the Japanese releases of Pokemon Red, Blue, Green, and Yellow, as well as all versions of Pokemon Gold, Silver, and Crystal, there is a glitch involving Substitute - no matter the accuracy of the move, if it is a move that absorbs HP (e.g. Absorb, Giga Drain, Mega Drain), the move will have a 100% chance to miss!

Clone Pokemon

**THIS GLITCH CAN DELETE YOUR GAME SAVE DATA.**
**This glitch requires 2 Gameboys and a link cable.**

Have one Pokemon game with a pokemon that you both want (generally a starting pokemon, a legendary, or Mewtwo). Have the other game have a pokemon that you wouldn't miss, as it will be deleted forever (Example: Level 4 Ratatta). Once you both have your pokemon, enter a trade. Now, trade the bad pokemon for the good pokemon, and at the end of the trade, right after the screen flashes "Waiting..." but before it flashes "Trade Completed," the person who originally owned the good pokemon should turn off their Gameboy or pull out the link cable (turning off the power is the preferred method, but should work). The person who originally had the bad Pokemon should have the message "Trade Completed" on their screen.

If done correctly, you will both now have the good pokemon. The person who originally had it turned off their Gameboy before it could save, so his gamepak doesn't know the trade ever took place. The second person's Gameboy remembers the trade, and has the new Pokemon.

Missing No. Kangaskhan.

Item's needed for glitch:
Pokemon Red
Master Ball (infinite is recommended)
Rare Candy
---
This can only be done on Red Version of Pokemon. Do the steps described for infinite items. When you encounter the bar shaped thing (also refered to as Missing No.), use a master ball (if you have infinite) and capture the Missing No.. WARNING: Only do this is if Missing No. is at level 80. Level 0 Missing No. WILL lock your game up. It will say that you captured #### n' #### as it's name will look in the screen. For some reason it will continue to attack. Just run. If you can't, keep trying until you do. Get Missing No. into your party and give it a Rare Candy. It will move to Level 81 and say that it is evolving. It evolves into... TAA-DAA!! Kangaskhan! This is no ordinary Kangaskhan. It has three attacks; Water Gun, Water Gun (again), and Sky Attack.

Safari Zone Pokemon Caught easy

1) Go to the Safari Zone and wander around until you run into one of the more rare and hard to catch pokemon.

2) Run away from it and immediately use dig, teleport, escape rope, fly, or anything else that will take you immediately out of the Safari Zone.

3) Surf down to the Seafoam Islands from Fushia City (Use repel if you got it to avoid encounters)

4) Surf up and down the East Coast of Seafoam. (Make sure you stay on the very edge so you are half on land half in the water)

5) Your first pokemon encounter should be the pokemon you last saw in the Safari Zone.

I highly recommend using the infinite item glitch to get loads of master balls first so you don't risk killing your quarry.... or worse being killed by it. Very nice little trick, that will save some serious annoyance when trying to catch Pokemon like Tauros and Ryhorn who just don't want to seem to want to stay in the safari balls.

The Old Man Glitch

This glitch requires you to have the Badges allowing the use of Fly and Surf, and Pokemon that can use these moves. You must also be able to reach Fuschia City or Cinnabar Island. First, head to Viridian City and speak with the old man near Route 2 who will teach you to catch Pokemon; view his tutorial. After doing so, Fly to Fuschia or Cinnabar and Surf to the Seafoam Islands. Once there, Surf on the coastline of the islands.

As you Surf, you may encounter a number of odd Pokemon. These Pokemon will differ, depending on the name you used as that of your Trainer. For example, the name "DANIEL" can make Snorlax or Electrode appear, among others. However, a common characteristic of them is that they are often above Level 100 and thus very powerful: if you manage to catch one somehow, you essentially have a very powerful Pokemon, and can even level it up further, as high as Level 255. (Note that some Pokemon may evolve into glitch Pokemon because of this.) That is the first benefit of this simple glitch.

Most people, regardless of name, should be able to encounter one of two Pokemon: Missingno. or 'M, both of which are glitch Pokemon. These two have special effects on the item in the sixth slot of your item bag, but that effect depends on whether you catch or defeat the Pokemon. If you defeat the Pokemon (or otherwise just do not catch it), the item in your Bag's sixth slot will be changed so that you have 128 of it; if you catch it, you will have 255 of it. (This is assuming you use an item that you can have multiple ones of.) This is very useful for mass-cloning valuable items, such as Master Balls, Rare Candies, or PP Maxes, or to clone TMs to sell for obscene amounts of money.

Quickly Reach the End (Japan Version)

Note that this glitch only works in the Japanese versions of Pokemon Red and Green Versions, Pocket Monsters Aka and Pocket Monsters Midori, respectively. It can only be executed early in the game (as in, it requires a new game), but will get you to the Hall of Fame and the ending in only around fifteen minutes.

After starting a new game, take a Potion from the PC and play the game as normal until you obtain Oak's Parcel from the PokeMart in Viridian City. On the way back to Pallet Town, get into a battle. Enter the items menu and hover over the Oak's Parcel item there and press Select. Then exit the menu and go to the Pokemon menu. Press Select while hovering over your Pokemon. While it doesn't truly switch your Pokemon with an item, it effectively switches around various amounts of data in the game, allowing you to warp to places based on how many steps you take before going through a doorway.

After running from this battle, go 73 steps, the last going through the door of the northeast house in Pallet Town. You will reappear on Route 16: go right five steps and down until you warp. You will be in the hidden part of the Cycling Road gatehouse: there, walk nine steps, with the last going through the northeastern doorway. After, go 45 steps east, the last of which you need to put going through the doorway to the Celadon Department Store. You will be in the glitched version of the Hall of Fame, and then the game will play the ending sequence as if you had won the Pokemon League championship, thus allowing you to see the end of the game far earlier than is normal.

The Mew Glitch and Quick Level 100 Pokemon

The Mew Glitch, in its simplest form, can be executed only before getting the Cascade Badge from the Cerulean Gym. First, go onto Route 24 to the north of Cerulean and obtain an Abra there in the grass to the west of Nugget Bridge: be sure not to battle the Youngster in the grass. (The former is not possible in Pokemon Yellow, meaning you will need to trade an Abra to that version. Other Pokemon with Teleport also work.) When you obtain the Abra, go heal in the Cerulean Pokemon Center, so as to be able to have Abra Teleport you there.

Return to Route 24 and to the grass where the Abra was found. You should see a Trainer in the grass: go north until he is off-screen, then get due north of his position. (Now is a good time to save, since failure in this instance is irreversible.) Go south one step and rapidly press Start as you do so: as the Trainer appears on-screen, the menu should appear. Go to the Pokemon menu and have your Abra Teleport you back to Cerulean City; you'll know if this effort was successful if the Trainer gets an "!" mark above their head as you warp. This tricks the game into believing you're in-battle, too, disabling the Start Button menu. When you return to Cerulean, enter the Gym and battle the swimming Trainer. After you do this, head back to Route 24. As you do so, the menu will appear; leave it and a Level 7 Mew will appear.

There are other variants to this glitch that originally only used to find the now-unavailable Mew: however, all methods require a Trainer, such as the aforementioned Youngster, that begins a battle the moment you're on-screen and in his/her vision. It is all based on the last-seen Pokemon's Special stat: the above method is an early way to get a Pokemon with the Special stat of 21 to be the last-seen, thus triggering the appearance of Mew, since Mew's internal ID in the game is 21. Other Pokemon (it can be wild or a Trainer's) can be used to get different Pokemon: the ability to find Ditto late in the game will also allow full manipulation of this process (so long as the Ditto uses Transform in the battle) as you yourself can view the Special stat of the Transformed Pokemon. This can be used to get any of the Pokemon in the game, even several glitch Pokemon or cause a few battles with Glitch Trainers.

There is one further derivative for this glitch: if you use Growl in the battle with the Pokemon whose Special stat corresponds to the Pokemon you wish to have, you can affect the Level of the Pokemon you get. For each Growl used, the Level goes down by 1: the game maxes at six uses, meaning you can get a Level 1 Pokemon, and this is the only method in which to do so. However, the EXP. growth formula for Level 1 Pokemon is glitched: the next-level EXP. is essentially a large negative number. If the Level 1 Pokemon gains any EXP. in battle - you simply need to switch it out of battle once it's in - it will go straight to Level 100. It will still obey you, since it's your Pokemon as well. However, this effect only works on Pokemon that cannot evolve anymore, such as Charizard, Tauros, Raichu, or Mew.

Hyper Beam Recharge Perpetuation

This glitch can be executed on Pokemon who have used Hyper Beam and are Frozen during their recharging turn. If you use Haze on this Pokemon, they will thaw out - however, they will always be recharging from their Hyper Beam, meaning they and their Trainer can do nothing until you defeat it. You can capitalize on this with healing across the party, massive stat boosts, and inevitably killing the Pokemon.

Invulnerability

This glitch is executed when a Pokemon using Fly or Dig becomes Paralyzed before the turn on which they attack: it is only done by being Paralyzed when you are high up in the air when using Fly. If such occurs, you will be invulnerable. This glitch lasts until your Pokemon uses Fly or Dig again and is successful in doing so, you switch Pokemon, the Pokemon faints, or the battle ends.

Boost Leech Seed's Absorption

Leech Seed is a move well-known for absorbing 1/16 of the target's HP and healing the user of the move by the same amount. However, you can actually boost this damage through the unintended effects of Toxic. When you use Toxic to Badly Poison a foe, and then use Leech Seed on them, Leech Seed's damage will also increment: thus, you regain 1/16, then 1/8, then 3/16, then 1/4, and so on, of your HP. Toxic will also be taking effect in this time, dealing the same amount of damage. In other words, you not only regain tons of HP, but also double the damage of Toxic, from one point of view.

Skip the Pewter City Gym

This obviously can only be done before beating Brock in Pewter City. At the east end of town is a kid who will take you to the Pewter Gym if you have not beaten him yet. One tile before walking into his line of sight, open the pause menu and hover the cursor over "SAVE". Now, exit the menu with B, then walk in front of the kid. Throughout the conversation that follows, continue pressing B to advance the text. Immediately after the texts ends, press Start, then save the game. Let the kid walk you to the Pewter Gym, then enter the pause menu and reset the console.

After the game reloads, you'll be taken to the Gym again. This time, continue back to Route 3's entrance. This time, the kid won't be there. However, be sure hug the north side of the rock wall as you go east: you'll trigger the conversations again if you do not.

Note, too, that you must beat the Pewter Gym eventually to beat the game. This is best used for those who intend to go back later with a better Pokemon party, such as those who started with Charmander. There is also a walk-through-walls glitch enabled by this. After you execute the glitch and regain control, speak again with the kid from the east side, after which you can walk through walls, but only if you have a Bulbasaur in the second slot of your party at Level 8.

Evolve Pokemon without Stones

To execute this glitch properly, you need a Pokemon who evolves via a Stone (Fire Stone, Leaf Stone, Moon Stone, Thunderstone). This only works with Pokemon whose internal ID number is equal to that of the item used to evolve it. So long as you send out such a Pokemon as your lead in the battle, and defeat the foe with a different Pokemon, this can be done. What Pokemon you switch to is important, as noted later.

First, send out the Stone-needing Pokemon as your lead. On the first turn, switch him out for the Pokemon that you do not want to evolve: doesn't matter which. When the Pokemon beats your foe, if the shared EXP. makes the Stone-needing Pokemon level-up, the same Pokemon will evolve.

This list describes who you must switch to for this to work:

- If you need a Thunderstone evolution, win the battle with Growlithe.
- If you need a Moon Stone evolution, win the battle with Exeggutor.
- If you need a Water Stone evolution, win the battle with Onix.
- If you need a Leaf Stone evolution, win the battle with Psyduck.
- If you need a Fire Stone evolution, you must win the battle with a Missingno. whose internal decimal index number is 32, which is impossible to get without the use of other glitches.

Walk Through Walls

First, begin this by going to the Safari Zone in Fuschia. Arrive there with only one Pokemon in your party, and this Pokemon must be Poisoned (PSN). Enter the Safari Zone gatehouse and pay $500 to begin playing. Immediately upon entrance, go back into the gatehouse and, when asked if you wish to leave, say "No.". Then save the game and reset the console, then reload your save file.

When you reload, begin counting every single step you take - this is very crucial to this glitch. When you reload, go into the Safari Zone building and opt to not play the game. Walk around now and be sure to do so near a ledge. Count until you have taken 499 steps and land the 499th step next to the ledge. (You can also count for 124 flashes of the screen, due to Poisoning, and 3 additional steps.) Heal your Pokemon periodically as well so that they do not faint (keeping the Poison active).

On the 500th step, do it so that you walk off the aforementioned ledge for it, thereby ending your Safari Game from earlier in mid-air. You will return into the Safari Zone gatehouse. Do not try leaving through the exit or your game will crash! This is why I mentioned keeping Poison active: you have to have your Poisoned Pokemon - your lone Pokemon in the party - faint by walking around due to Poison. You will then return to the last-used Pokemon Center, your Pokemon fully healed - however, there's a key difference in that you now can walk through walls and across water - basically anywhere you wish! The effects of this glitch will last until you enter a battle or speak with an NPC or enter a building.

Invisible PC

In the Celadon Hotel, you will notice that the graphics and internal structure of the building are much the same as that of a Pokemon Center. There is even a PC here, although it is invisible: it is in the same spot as a normal Pokemon Center along the east wall. The same is also true of some of the Rest Houses in the Safari Zone that have Pokemon Center-like design. You can interact with this PC as normal to insert and withdraw your Pokemon.

However, take note that if saving is done your actual location will not be saved. This can be used to some degree for sequence-breaking glitches and speed-running by saving in one area by changing PC boxes, then reloading the file. You'll have all your progress done as before, but your location will be the same the file before this save. For example, you can save normally in Pallet Town, then do so in the Celadon Hotel by using its invisible PC. When you reload, you'll have met all of the progress you did between Pallet Town and the Celadon Hotel but will be back in Pallet Town.

Alter Toxic Damage

Normally when under the effects of Toxic ("Bad Poisoning"), your Pokemon takes incrementing amounts of damage: 1/16, 1/8, 3/16, and so on, of their max HP. You can negate this by switching out; when the Pokemon returns, it will only be taking a flat 1/8 damage like regular Poisoning.

Negate Burn/Paralysis Stat Losses

Normally, when Burned, a Pokemon's Attack stat is halved, and when Paralyzed their Speed is halved. However, if you use Swords Dance (if Burned) or Agility (if Paralyzed), the stat loss is negated. For example, under the intended mechanics, Swords Dance and Burn would return you to normal damage output, but it actually doubles your damage output. The same is true for Speed, Paralysis, and Agility.

Struggle Glitch

Normally in Pokemon, the move Struggle (used when a Pokemon is at 0 PP for all moves) is intended to be a typeless move. However, in these games it is mistakenly coded as a Normal-type move. This means that you can use a Ghost-type Pokemon against them and easily win as they won't be able to hurt you.

Stat Boosting Errors

During the game, you will find that several Gym Badges actually boost your stats, like Attack, specifically with a multiplier of 1.125x; similarly, Burn halves Attack and Paralysis quarters Speed. While not intended to be applied multiple times to the same stat, they can be by affecting other stats. (For example, to stack Attack boosts from the BoulderBadge, get hit by Tail Whip, which affects Defense.) The multipliers get reapplied. You can use this to tank hits from Pokemon that use the moves; an example would be taking three Tail Whips, resulting in a 42.4% boost in Attack from the BoulderBadge. You can also use this to affect the opponent's stats; for example, if you Burn them, then hit them with Tail Whip, their Attack is halved a second time! Note, however, that directly affecting the stat you want to stack boosts/losses on - for example, using Growl on a Burned Pokemon, or using Belly Drum while stacking Attack boosts - will nullify the stacking, returning the values to their intended quantities.

Further, when a Pokemon raises its own stat stages, modifiers due to Paralysis or Burn are applied to the opposing Pokemon even though they don't possess them. For example, if your Pokemon is Burned and uses Double Team to boost evasion, the opponent's Attack stat gets halved, even though they are not burned.

Level-Based Damage Boost

For reasons unknown, if your Pokemon has a Level that ends in 0, 3, 5, or 8, their damage will be boosted by approximately 3%. Thus, it is possible for you to have Pokemon with the same Attack stat, but because one is Level 98 and the other is Level 99 with slightly lower DVs, the Level 98 one can deal the same or more damage.

Now fly to Cinnabar Island and surf on the right edge of the island. You should be able to battle a weird Pokemon called MissingNo. It's appearance is kind of weird. Don't let it attack you or don't capture it or it will ruin your game! Just run or beat him with powerful quick attacks.

When you reload, begin counting every single step you take - this is very crucial to this glitch. When you reload, go into the Safari Zone building and opt to not play the game. Walk around now and be sure to do so near a ledge. Count until you have taken 499 steps and land the 499th step next to the ledge. (You can also count for 124 flashes of the screen, due to Poisoning, and 3 additional steps.) Heal your Pokemon periodically as well so that they do not faint (keeping the Poison active).

On the 500th step, do it so that you walk off the aforementioned ledge for it, thereby ending your Safari Game from earlier in mid-air. You will return into the Safari Zone gatehouse. Do not try leaving through the exit or your game will crash! This is why I mentioned keeping Poison active: you have to have your Poisoned Pokemon - your lone Pokemon in the party - faint by walking around due to Poison. You will then return to the last-used Pokemon Center, your Pokemon fully healed - however, there's a key difference in that you now can walk through walls and across water - basically anywhere you wish! The effects of this glitch will last until you enter a battle or speak with an NPC or enter a building.

Invisible PC

In the Celadon Hotel, you will notice that the graphics and internal structure of the building are much the same as that of a Pokemon Center. There is even a PC here, although it is invisible: it is in the same spot as a normal Pokemon Center along the east wall. The same is also true of some of the Rest Houses in the Safari Zone that have Pokemon Center-like design. You can interact with this PC as normal to insert and withdraw your Pokemon.

However, take note that if saving is done your actual location will not be saved. This can be used to some degree for sequence-breaking glitches and speed-running by saving in one area by changing PC boxes, then reloading the file. You'll have all your progress done as before, but your location will be the same the file before this save. For example, you can save normally in Pallet Town, then do so in the Celadon Hotel by using its invisible PC. When you reload, you'll have met all of the progress you did between Pallet Town and the Celadon Hotel but will be back in Pallet Town.

Alter Toxic Damage

Normally when under the effects of Toxic ("Bad Poisoning"), your Pokemon takes incrementing amounts of damage: 1/16, 1/8, 3/16, and so on, of their max HP. You can negate this by switching out; when the Pokemon returns, it will only be taking a flat 1/8 damage like regular Poisoning.

Negate Burn/Paralysis Stat Losses

Normally, when Burned, a Pokemon's Attack stat is halved, and when Paralyzed their Speed is halved. However, if you use Swords Dance (if Burned) or Agility (if Paralyzed), the stat loss is negated. For example, under the intended mechanics, Swords Dance and Burn would return you to normal damage output, but it actually doubles your damage output. The same is true for Speed, Paralysis, and Agility.

Struggle Glitch

Normally in Pokemon, the move Struggle (used when a Pokemon is at 0 PP for all moves) is intended to be a typeless move. However, in these games it is mistakenly coded as a Normal-type move. This means that you can use a Ghost-type Pokemon against them and easily win as they won't be able to hurt you.

Stat Boosting Errors

During the game, you will find that several Gym Badges actually boost your stats, like Attack, specifically with a multiplier of 1.125x; similarly, Burn halves Attack and Paralysis quarters Speed. While not intended to be applied multiple times to the same stat, they can be by affecting other stats. (For example, to stack Attack boosts from the BoulderBadge, get hit by Tail Whip, which affects Defense.) The multipliers get reapplied. You can use this to tank hits from Pokemon that use the moves; an example would be taking three Tail Whips, resulting in a 42.4% boost in Attack from the BoulderBadge. You can also use this to affect the opponent's stats; for example, if you Burn them, then hit them with Tail Whip, their Attack is halved a second time! Note, however, that directly affecting the stat you want to stack boosts/losses on - for example, using Growl on a Burned Pokemon, or using Belly Drum while stacking Attack boosts - will nullify the stacking, returning the values to their intended quantities.

Further, when a Pokemon raises its own stat stages, modifiers due to Paralysis or Burn are applied to the opposing Pokemon even though they don't possess them. For example, if your Pokemon is Burned and uses Double Team to boost evasion, the opponent's Attack stat gets halved, even though they are not burned.

Level-Based Damage Boost

For reasons unknown, if your Pokemon has a Level that ends in 0, 3, 5, or 8, their damage will be boosted by approximately 3%. Thus, it is possible for you to have Pokemon with the same Attack stat, but because one is Level 98 and the other is Level 99 with slightly lower DVs, the Level 98 one can deal the same or more damage.

X Accuracy Trick

Unlike later games in the Pokemon series, in this game X Accuracy will make every move you use - until you switch out or are KO'ed - 100% likely to hit, no matter the nature of the move. Even those that are one-hit KO moves like Horn Drill, whose accuracy calculation are special, are 100% likely to hit, so it becomes easy to spam Horn Drill, Guillotine, etc., after the use of an X Accuracy!

Vending Machine Glitch

Atop the Celadon Dept. Store are several Vending Machines. You can buy Fresh Water, Soda Pop, and Lemonade from them. There is a glitch involving the costs of these items - if you can afford the Fresh Water ($200), but neither of the other two ($300 & $350), you can still buy the latter two items. Your money will deplete to zero afterwards.

Drain Move Substitute Glitch

In the Japanese releases of Pokemon Red, Blue, Green, and Yellow, as well as all versions of Pokemon Gold, Silver, and Crystal, there is a glitch involving Substitute - no matter the accuracy of the move, if it is a move that absorbs HP (e.g. Absorb, Giga Drain, Mega Drain), the move will have a 100% chance to miss!

Enter your item menu and go to the fourteenth item. Press select, b, b. Now you're out of the menu. Enter a grassy area into battle. 4. select pokémon. go with your cursor to pidgey and press a. you will see that the pokémon becomes glitched. now escape from battle. 5. As a result your second item will have a quantity of 67, but other items are still glitched. 6. Switch the second item with the fourteenth item. Repeat steps 3 and 4. Now you will have all your items normal again with the addition of 67 of your desired item. Your pidgey is however unusable for this glitch in the future and I typically release it and catch a new pidgey for another item duplication.

Saffron City Gym Glitch (Red & Green JP-only)

In Pokemon Red and Green's Japanese versions, let's assume you lose to Sabrina in the Saffron City Gym. If you return to her afterwards and speak to her, she will nonetheless act as if you won, and give you the Badge and TM for Psywave as usual.

Surfing Glitch (Red, Blue & Green JP-only)

Unlike in Yellow Version and the localizations of the games, in the Japanese Red, Blue, and Green, you are capable of Surfing starting from the north tile of cliffsides. This is most helpful in the Seafoam Islands, enabling you to find Articuno and bypass the high-speed currents without dealing with the annoying boulder puzzle involved.

Repeat In-Game Trades (JP-only)

On the Japanese releases of Pokemon Red, Blue, and Green, you can repeat the in-game trades normally only doable once. Before you begin the trade, go into your bag, hover over an item, and press Select. Exit out of the menu and begin the trade: while in your party menu, swap the Pokemon you intend to trade with another in the order, then trade it. After receiving the Pokemon from the trade you'll find yourself able to execute it again; you can execute this as many times as desired.

PP Pokemon Morphing (JP only)

This only works in the Japanese Red, Blue, and Green. You need at least two Pokemon and 16 items.

Put a Pokemon with no HM moves into slot two of your party; this Pokemon preferably is worthless since it'll be transformed by the end. In slot one, put a Pokemon that has one of its moves' current PP matching the ID of your desired Pokemon (such as 21 PP remaining for Mew). Enter your Bag and press Select on the 16th item. Press B twice to exit, then enter battle. Press Select again on the move with the desired PP, and end the battle. Go to the Daycare and drop off and withdraw the second Pokemon in your party; on its return it'll be of the same species as the PP of the swapped move!
