Pokémon Crystal remains a beloved classic in the franchise, celebrated for its vibrant Johto region, introduction of animated sprites, and the compelling Suicune subplot. For many, it represents the pinnacle of the Game Boy Color era. Whether you’re revisiting this gem for a dose of nostalgia or exploring it for the first time, cheat codes can offer a fresh and exciting way to experience the game. This comprehensive guide will delve into the world of Pokémon Crystal cheats, from classic GameShark codes to famous in-game glitches.

Understanding Pokémon Crystal Cheats
Before we dive into the codes themselves, it’s essential to understand what we mean by ‘cheats’ in the context of a retro game like Pokémon Crystal. Primarily, these are codes entered via a cheat device, the most famous being the GameShark. This physical cartridge would sit between your Game Boy and the game, allowing you to manipulate the game’s memory to achieve desired effects. Today, most players use emulators, which have built-in cheat engines that replicate the functionality of a GameShark, making it easier than ever to bend the rules of Johto.
How to Use Pokémon Crystal Cheats: A Step-by-Step Guide
The method for applying cheats depends entirely on how you’re playing the game. The process for original hardware is vastly different from using a modern emulator.
Using a GameShark on Original Hardware
If you’re a purist playing on an original Game Boy Color or Game Boy Advance, you’ll need a physical GameShark device. The process is straightforward:
- Insert the Pokémon Crystal cartridge into the GameShark.
- Insert the GameShark into your Game Boy.
- Power on the console. The GameShark menu will appear.
- Select the option to add new codes and carefully input the desired cheats from the list below.
- Enable the codes you wish to use and then start the game.
Using Cheats on an Emulator
For the majority of players, an emulator is the go-to choice. Popular options include Visual Boy Advance (VBA), mGBA, and RetroArch. While the exact menu names may vary slightly, the general process is universal:
- Load your Pokémon Crystal ROM in the emulator.
- Find the ‘Cheats’ or ‘Tools’ menu in the emulator’s toolbar.
- Select ‘Cheat list’ or ‘Add new cheat’.
- A window will pop up asking for a description and the code itself. You may also need to select the code type (usually GameShark or Code Breaker).
- Enter the code exactly as written, give it a memorable name (e.g., ‘Infinite Master Balls’), and save it.
- Ensure the new cheat is enabled (often a checkbox next to the name). The effect should be immediate.
Important: Always back up your save file before experimenting with new cheats! They can sometimes cause unexpected glitches or, in rare cases, corrupt your save data.
The Ultimate Pokémon Crystal Cheat Code Compendium
Master Code (Required for Most Cheats)
Think of the Master Code as the key that unlocks the door for all other cheats. For most codes to function correctly, you must have the Master Code entered and activated first. It’s the foundational cheat that stabilizes the game for further memory manipulation.
- Master Code: 91C089DA
Infinite Items Cheats
Tired of grinding for money to buy Potions or saving that one Master Ball for the perfect moment? With these codes, you can have an endless supply of any item. Note that the ‘xx’ in the code should be replaced with the two-digit hex value for the desired item.
- Infinite Item in PC Slot 1: 016321D8
- Infinite Item in Bag Slot 1: 01xx7CCF
Here are some popular item values for ‘xx’:
- Master Ball: 01
- Ultra Ball: 02
- Rare Candy: 28
- Full Restore: 13
- Max Revive: 1A
- Nugget: 1F
For example, to get infinite Master Balls in the first slot of your bag, the code would be 01017CCF.
Walk Through Walls Cheat
One of the most iconic video game cheats of all time, the ‘Walk Through Walls’ code lets you bypass any obstacle. Explore hidden areas, sequence-break the story, or simply take the shortest path through a cave. Be careful, as you can get stuck in places you’re not supposed to be.
- Walk Through Walls: 9100FACB
Wild Pokémon Modifier Cheats
This powerful cheat allows you to decide which Pokémon appears in the wild. It’s the perfect way to catch rare Pokémon like Larvitar early on or even capture legendary Pokémon that are otherwise unobtainable, like Mew or Celebi.
- Wild Pokémon Modifier: 91xxF2DA
Replace ‘xx’ with the hex value of the Pokémon you want to encounter. Here are some of the most sought-after values:
- Bulbasaur: 99
- Charmander: B0
- Squirtle: B1
- Mewtwo: 83
- Mew: 15
- Lugia: F9
- Ho-Oh: FA
- Celebi: FB
For a guaranteed encounter with Celebi, you would activate the code 91FBF2DA and then walk into any patch of grass.
Shiny Pokémon Cheat
Want to fill your team with rare, alternately-colored Pokémon? This code makes every wild Pokémon you encounter a Shiny.
- Encounter Shiny Pokémon: 9107F2DA
Infinite Money Cheat
Never worry about the cost of items again. This cheat will instantly max out your wallet, giving you all the spending power you need.
- Max Money: 019973D1, 019974D1, 019975D1

Famous Pokémon Crystal Glitches (Cheats Without a Device)
Beyond GameShark codes, Pokémon Crystal is home to several famous glitches that players can exploit without any external hardware. These are part of the game’s code and can be triggered by performing a specific sequence of actions.
The Celebi Egg Glitch
This is arguably the most famous glitch in the game, allowing players to obtain the mythical Pokémon Celebi, which was originally an event-exclusive. It’s a complex process, but highly rewarding. It involves tricking the game into giving you an egg that hatches into Celebi by manipulating a specific set of Pokémon in your party and using the move ‘Beat Up’. The steps are too intricate for a brief summary, but it requires a Sneasel that knows Beat Up and a specific sequence of Pokémon cloning to set up your party correctly. The result is a glitched egg that hatches into Celebi.
Pokémon and Item Cloning Glitch
This classic glitch from Gold and Silver returns in Crystal. It allows you to duplicate any Pokémon along with its held item. This is the ‘legit’ way to get multiple Master Balls or clone your starter Pokémon. The process involves the PC storage system:
- Go to any Pokémon Center and open the PC.
- Deposit the Pokémon you want to clone into a box.
- Switch to a different box. As the game says ‘SAVING… DON’T TURN OFF THE POWER,’ you must turn off your console.
- The timing is crucial. You need to power down right after the word ‘SAVING’ appears but before the sentence is complete.
- When you turn the game back on, the Pokémon will be in your party AND in the PC box, successfully cloned.
Frequently Asked Questions (FAQ)
Can you get banned for using cheats in Pokémon Crystal?
Absolutely not. Pokémon Crystal is a single-player, offline game. There are no online services to monitor your activity, so you can use cheats freely without any risk of being ‘banned’.
Do Pokémon Crystal cheats work on the 3DS Virtual Console?
Unfortunately, no. The official Virtual Console versions of Pokémon Crystal released on the Nintendo 3DS do not have a built-in interface to input GameShark codes. However, glitches like the cloning glitch may still work, though some might have been patched.
What is the best cheat for Pokémon Crystal?
This is subjective and depends on your goal. For quickly training a team, the Infinite Rare Candy cheat is invaluable. For completing the Pokédex, the Wild Pokémon Modifier and Infinite Master Ball cheats are the most powerful combination.
How do you get Celebi in Crystal with cheats?
The easiest and most reliable method is using the Wild Pokémon Modifier GameShark code. Simply enter 91FBF2DA, activate it, and walk in the grass. The next wild Pokémon you encounter will be Celebi.
Can cheats corrupt my save file?
Yes, this is the most significant risk. Using too many codes at once, using poorly written codes, or accidentally saving at the wrong moment can lead to game freezes, graphical errors, or complete save file corruption. Always back up your save file before trying a new cheat, especially on an emulator where it’s as simple as copying a file.
A Final Word of Caution
Cheating can unlock a new dimension of fun, but it should be done responsibly. Activating too many complex codes simultaneously can cause the game to crash. The ‘Walk Through Walls’ cheat, while fun, can easily get you stuck, forcing a reset. Always save your game before enabling a new cheat, and preferably, keep a ‘clean’ save file backed up somewhere safe, just in case.
Conclusion: A New Way to Play a Classic
Pokémon Crystal is a masterpiece that stands the test of time. Whether you use cheats to build your dream team of shiny Pokémon, bypass the grind with infinite Rare Candies, or explore the world in new ways by walking through walls, these codes provide a powerful toolkit to customize your adventure. From GameShark codes to legendary in-game glitches, you now have everything you need to become the ultimate master of the Johto region. Have fun, experiment, and rediscover the magic of Pokémon Crystal.
