Glitches

  • 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.

  • 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!

  • 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.

  • 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.

  • 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!

  • Get 2 level 100 Mews before Misty!!!

    Have ABRA in your party. Go up Nugget bridge in Cerulean City and to the left to the trainer facing north. Stand right to his left and make sure he doesn't see you. Head north until he is off screen. Go one step east. Step south and pause the game before he has a ! over his head. Use teleport. Fight the first trainer in Cerulean gym and use Growl 6 times. Kill his Pokemon and go back to Nugget Bridge. The game will pause automatically. Press B to find a level 1 Mew. Catch it and put it at the front of your party. Go in tall grass, find a wild Pokemon, and switch Mew with a different Pokemon. Kill the wild Pokemon. Mew will level up to 100. Do this glitch again with the trainer facing north on the route to Bill's house to get another level 100 Mew.

  • Have Pikachu instantly like you!

    When you first start your game, you will have 1 potion in your pc that's in your room. Get it out. Continue playing the game untill you get Pikachu but haven't battled Gary's Eevee yet. Use the potion on Pikachu 5 times (even though it won't have any effect). Fight Gary and WIN. After the battle, when your Pikachu comes out of the Pokeball. He will like you.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

Secrets

  • Get through grassy areas without a single random encounter.

    Once you've obtained the HM Cut you can use it to teach some of your pokemon the attack of the same name.
    This ability now cannot only be used to cut down certain trees but also to get rid of any grass so you don't have to bother with any random encounters.
    When saving and loading or leaving and reentering the area you used cut in, the grass will have returned.

  • 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.

  • Pikachu's Beach Mini-Game

    Use the Pikachu from your Pokemon Yellow in every match in the Tournament mode of Pokemon Stadium. Pikachu should learn Surf. Now go south of Fuschia City and into the house at the beach. Talk to the man inside. Make sure Pikachu is in your party. You should be able to play a mini-game.



  • 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!
