Pokemon Crystal Slot Machine Glitch

As far as I know, some slots are luckier than others. This is implied by a man at Celedon. However, the man does not tell you WHICH slots are lucky. I couldn't find any information on which ones are luckier, but I think it might have something to do with your trainer ID. There is a video by Crystal that might be what you're looking for. Gold & Silver Crystal Slot 1 01xxB8D5 91xx93D8 Slot 2 01xxBAD5 91xx95D8 Slot 3 01xxBCD5 91xx97D8. (Crystal only) 7F - Card Key 80 - Machine Part 81 - Egg Ticket (Crystal only) 85 - Basement Key 86 - Pass AF - Squirtbottle B2 - Rainbow Wing. Head back to our Pokemon Crystal cheats page for a load more cheats and tips for Pokemon Crystal. If a 7 does not originally show up, the machine sometimes rolls it to a 7. For the third row, do the same as you did for the second row. The machine either spins itself to a 7, Golem come down.

PRAMA Initiative a également une page sur Duplicate key items glitch.

This duplicate Key Items glitch is a glitch in Pokémon Gold, Silver and Crystal, in which the player swaps two identical key items (obtained via byte shifting from ????? party overloading) in the Key Items pocket to obtain items (such as infinite use Rare Candies) or allow the player to set up an expanded Balls pocket with more than the maximum amount of items.

The reason the player obtains arbitrary items in the Key Items seems to be related to the facts that both: item quantities in the Key Items do not exist, and the game tries to merge the two stacks into one stack with a combined quantity.

Using the expanded Balls pocket, the player is able to use TMs and HMs from the wrong pocket for their own glitchy effects and arbitrary code execution (e.g. via TM33 in English Crystal, TM15 in English Crystal and TM25 in English Gold and Silver).

These TMs run code from the enemy Trainer's fifth Pokémon's nickname character 3 (TM33) or somewhere in the expanded Balls pocket.

Furthermore, the player can also enable glitch Pokédex categories (such as glitch Pokédex mode 09 in English Crystal for arbitrary code execution in the expanded Balls pocket) as well.

Via arbitrary code execution

This trick requires being able to set up arbitrary code execution on Pokémon Red, Blue, and Yellow. You may use 8F or ws m in Generation I to change the catch rate of Pokémon to value(s) corresponding to key items. (see The Big HEX List to see which IDs correspond to which key items)

Via bad clone glitch and ????? party overloading

Using tricks from ????? party overloading, the player can manipulate a key item as a held item on a Pokémon. This can be done in practise by using move PkMn w/o mail to obtain a seventh Pokémon, placing a Pokémon in slot 1 with a specific move then performing 1-4 shifts (depending on the position of the move) to shift the move ID into an equivalent held item ID. (see The Big HEX List to see which IDs correspond to which moves and held items)

Infinite items examples

Example 1:

If we have the following items:

Lost Item

Lost Item

Card Key

Basement Key


Then swapping the first Lost Item with the second Lost Item will make us lose the original second Lost Item and Card Key but the second Lost Item will turn into a Master Ball with quantity 133 (Basement Key's index number). The Master Ball can be used infinitely because it is in the wrong pocket.

If we have the following items:

Lost Item (index no. 130)

Lost Item (index no. 130)

Card Key (index no. 127)

Basement Key (index no. 133)

Cancel (index no. 255)

If we swap the first Lost Item with the second, we lose the original second Lost Item and the Card Key, but the second Lost Item will turn into a Master Ball with quantity 133 (Basement Key's index number). The reason why the second item turns into a Master Ball in this example is because the Card Key is index number 127 (7F) and the Lost Item is index number 130 (82). Adding these together gives 257, but since items are defined by one byte, this becomes 257 modulo 256 or 1, which is Master Ball's index number.

Therefore we get:

Lost Item (index no. 130)

Master Ball (index no. 257 1) x133

CANCEL (index no. 255)

Example 2:

If the sum of the first Key Item's index number and the item below the second Key Item is greater than 100, then the third item is not lost, but becomes a BLK Apricorn (index no. 99). The second item identifier becomes equal to that of the sum of the first Key Item index number and the original third item minus 99. Its quantity is derived from the new third item identifier.

For example, consider the following Key Items pack:

Lost Item (index no. 130)

Lost Item (index no. 130)

Master Ball (index no. 1) x7

Bicycle (index no. 7)Cancel

If we swap the first Key Item with the second this gives us:

Lost Item (index no. 130)

Rare Candy (index no. 32 [130+1-99] )

BLK Apricorn (index no. 99)

Bicycle (index no.7)

CANCEL (index no. 255)


Expanded items pack

If you want to set up the expanded Balls pocket, change the catch rate of two Pokémon to 128 and 67 each. When traded to a Generation II game they will be holding Machine Parts and Secretpotions.

  1. On the game with two SecretPotions and two Machine Parts
  2. Put both Machine Parts in the last two slots of the Key Items pocket
  3. Swap both items, which will turn into a single slot
  4. Remove the Cancel item
  5. Put both SecretPotions in the last two slots of the Key Items pocket
  6. Swap these, and all bytes up to the Cancel in the Balls pocket will be shifted upwards

Expanded Balls pocket

Using specific duplicate key items, it is possible to enable the expanded balls pocket, which can later be used for memory corruption by swapping items in the pocket or arbitrary code execution via TMs/HMs outside of the correct pocket or glitch Pokédex categories.

First the key items pocket must be filled with 25 items including two Machine Parts and two Secretpotions:


  1. Put both Machine Parts in the last two slots of the Key Items pocket
  2. Swap both items to create Iron x99 and Blk Apricorn x10
  3. Put both SecretPotions in the last two slots of the Key Items pocket
  4. Swap these, and all bytes up to the Cancel in the Balls pocket will be shifted upwards, with the ID of the first item becoming the number of Balls.

Note that this is not the only way to access the expanded balls pocket. The Pokémon Speedruns wiki details a different method involving two Itemfinders.

The Game Corner has been a staple of every Pokemon game up to Generation IV. Here you can buy coins, test your luck, and win fabulous prizes, including new Pokemon and TMs you won't get anywhere else.

The Basics
You'll need a Coin Case, to be found in the Goldenrod Underground. At the main desk in Game Corner (in the top left corner) you can buy 50 coins for 1000P or 500 for 10,000P.

Slots and Games
Gold and Silver have two games now. The first is the basic slots game from Red and Blue: insert however many coins you want (1, 2 or 3, which add more rows on the slots where you can win prizes) and try and line up the same picture.

Slots Prize Table:
Three 7's: 300 coins
Three Poké Balls: 50 coins
Three Staryu: 15 coins
Three Squirtle: 10 coins
Three Pikachu: 8 coins
Three cherries: 6 coins

Getting one or two 7's seems to affect the game a little; you might see other Pokemon pop up from time to time to tip the balance of the game if you manage to pull off a 7..

The second game is Card Flip. New to the franchise, Card Flip allows you to pick one or several cards, place a bet on the winning card, and try to win. The less cards you pick the higher the yielding prize.

Prizes (Goldenrod)


TM14 Blizzard: 5500 Coins
An frosty blast of Ice-type damage is what you'll get using Blizzard. It's useful against the eighth Gym Leader and the Champion though it has low accuracy so watch out. Blizzard has a modest chance of freezing the opponent.

TM25 Thunder: 5500 Coins
This peal of electrical power will shock the living daylights out of certain Pokemon on Chuck and Pryce's respective teams. To add to the fear factor, Thunder will never miss when it's raining. It also might paralyze the target.

TM38 Fire Blast: 5500 Coins
A decently accurate and extremely powerful Fire-type move, Fire Blast will be immensively helpful in your fights against Jasmine and Pryce. It has a good shot at burning the target.

#063 Abra: 200 Coins
Makes catching this little Psychic-type a heck of a lot easier now that he can't escape with Teleport. Evolves into a Pokemon with one of the best Special Attack stats in the game (albeit reaching his last form via trade). If you do use him, your fights against Morty and Chuck might become a lot easier.

#104 Cubone: 800 Coins.
A neat addition to your team can be the elusive Ground-type Cubone for just 800 coins. Its Defenses will be a good asset against Whitney, Morty, and Chuck, and its STAB attacks will be great for the fight against Morty and Pryce.

Pokemon Crystal Slot Machine

#202 Wobbuffet: 1500 Coins.
An interesting Psychic-type that plays differently than any other Pokemon in the game. Huge HP stat means it can take any hit then pay back for double with Counter and Mirror Coat.

Prizes (Celadon)

TM32 Double Team: 1500 Coins
Boosts evasion to make the foe's moves miss. This works great both ingame and competitively, though watch out: you may lose all your friends if you try it on them.

TM29 Psychic: 3500 Coins
The most powerful Psychic-type move in the game. It has raw strength behind it and is great for dealing with pesky Fighting-type and Poison-type Pokemon like Hitmontop and Gengar.

TM15 Hyper Beam: 7500 Coins
A very powerful Normal-type move. 150 Base Power, but forces you to recharge after using. Attach it to a fast Pokemon with great Attack power (like Entei) and go hog wild.


#025 Pikachu: 2222 Coins
The mascot of Pokemon can be yours for just 2222, or if you wait a bit and go catch one in Viridian Forest. There's not much to be said about this Pokemon - though unless you get Pichu from your second egg, this is the earliest you can get the Electric-type mouse.

#137 Porygon: 5555 Coins
Exclusive to the slots, Porygon is very expensive. If you're looking for a strong battler, it's not going to be Porygon, though it has a fun novelty to it you could try and make work with its neat movepool. Get the Upgrade though from Silph Co. and you can have some interesting battles using Porygon2.

#246 Larvitar: 8888 Coins
This is your only chance to get the plucky Rock/Ground-type before you can go to Mt. Silver. If you want to raise it to Level 55 before that you will have its mighty final stage Tyranitar, one of the few Dark-types, at your disposal for the match against Red.
