Must-Have Pokemon Crystal Cheats

Walk Through Walls Cheat

The walk through walls cheat is one of the most popular Pokemon Crystal codes, allowing you to move through any obstacle in the game. This can help you access areas early, skip puzzles, or explore normally inaccessible locations.

Primary Code: 0108D3CF

Alternative Code: 0108D7CF

To activate this cheat, enter the code in your emulator’s cheat menu. Once enabled, your character can walk through walls, trees, water, and buildings. Be careful when using this code – walking into certain areas can cause the game to crash or freeze, especially in cutscenes or special encounters.

Important Notes:

  • Save before entering unknown areas
  • Avoid using this code during story-critical moments
  • Some areas may cause graphical glitches
  • Turning off the code while inside walls can trap your character

Common Issues: If the game freezes, try moving to a different area before turning off the cheat. Some players report that the code works better in certain regions than others.

Infinite Money Cheat

Having unlimited money eliminates the need to grind for Poke Dollars, allowing you to buy unlimited items, Pokeballs, and healing supplies. This is one of the safest and most useful cheats available.

Money Max Codes:
019973D5
019974D5
019975D5

Enter all three codes together to set your money to the maximum amount (999,999 Poke Dollars). The effect is immediate – check your trainer card to see the updated balance.

Alternative Single Code: 019947D5 (less reliable)

This cheat has a very low risk of causing game issues and works consistently across all major emulators. It’s perfect for players who want to focus on catching and training Pokemon without worrying about running out of funds.

Unlimited Rare Candies Cheat

Rare candies instantly level up your Pokemon without requiring battle experience. With unlimited rare candies, you can quickly build a powerful team for challenging battles or complete your Pokedex faster.

Primary Code: 0120F6D5

Instructions:

  1. Activate the cheat code
  2. Access any PC in the game
  3. Withdraw items from “Bill’s PC”
  4. Look for Rare Candy (x99 or x999)

The rare candies will appear in your PC item storage. You can withdraw as many as needed and use them on any Pokemon to instantly increase their level by 1.

Important Considerations:

  • Pokemon leveled only with rare candies may have weaker stats
  • Evolution stones are still required for some evolutions
  • Some moves are still learned at specific levels

Alternative Item Modifiers:
Master Balls: 0101D1D2
Ultra Balls: 0101D2D2
Full Heal: 0101DDD5
Full Restore: 0101DED5

Master Ball Cheat

Master Balls have a 100% catch rate on any Pokemon, making them invaluable for catching legendary creatures or difficult-to-catch Pokemon. With unlimited master balls, you can complete your Pokedex much faster.

Primary Code: 0101D1D2

Usage Instructions:

  1. Activate the cheat code
  2. Access your bag or PC storage
  3. Look for Master Balls (x99 or more)
  4. Use them in battle to catch any Pokemon instantly

Unlike other Pokeballs, Master Balls never fail, making them perfect for catching legendary Pokemon like Lugia, Ho-oh, and the legendary beasts (Raikou, Entei, Suicune).

Pro Tip: Even with unlimited Master Balls, consider using regular Pokeballs for common Pokemon to maintain some gameplay challenge and preserve the thrill of catching rare creatures.

Pokemon Modifier Cheats

Wild Pokemon Level Modifier

This cheat allows you to set the level of wild Pokemon encounters, making it easier to train your team or catch high-level Pokemon early in the game.

Level 100 Code: 01FF1DD1

Alternative Level Codes:
Level 50: 01321DD1
Level 99: 01981DD1
Level 255 (glitch): 01FF1DD1

When activated, all wild Pokemon encounters will be at the specified level. This is useful for quickly training your team or catching high-level Pokemon for your party.

⚠️ Important: Be cautious when catching very high-level Pokemon (above 100). They may cause game instability or have corrupted stats. Stick to level 100 or below for best results.

Training Strategy: Use this cheat with a low-level Pokemon to gain massive experience points. A level 5 Pokemon defeating a level 100 wild Pokemon can gain multiple levels in a single battle.

Wild Pokemon Species Modifier

This advanced cheat allows you to encounter specific Pokemon in the wild, making it possible to catch creatures that would normally be version-exclusive or event-only.

Format: XXYY1DD1
Where XX = Pokemon ID, YY = Level

Popular Pokemon Codes:
Mewtwo: 01F51DD1
Celebi: 01FB1DD1
Lugia: 01F41DD1
Ho-oh: 01F51DD1

How to Use:

  1. Find the Pokemon ID number you want
  2. Enter the code with desired level
  3. Walk in grass, caves, or surf on water
  4. The specified Pokemon will appear

Complete Pokemon ID List:
Bulbasaur: 0099
Charmander: 00B0
Squirtle: 00B1
Pikachu: 0054
Eevee: 0166
Snorlax: 0084
Dragonite: 017E

These codes work best when used in areas with normal wild Pokemon encounters. Avoid using them in special areas or during story events.

Shiny Pokemon Cheat

Transform any wild Pokemon encounter into a shiny version with this popular cosmetic cheat. Shiny Pokemon have different coloration and are extremely rare (1 in 8192 chance normally).

Primary Code: 01087BD3

Alternative Code: 01087CD3

When activated, every wild Pokemon you encounter will be shiny. This doesn’t affect their stats or abilities – only their appearance and the sparkles that appear when they enter battle.

✅ Pro Tip: Combine this cheat with the Pokemon species modifier to encounter specific shiny Pokemon. Just enter both codes simultaneously for the best effect.

Important Notes:

  • Shiny status remains after turning off the code
  • Evolved Pokemon maintain their shiny status
  • Some Pokemon have very subtle shiny color differences
  • The code affects only wild encounters, not trainer battles

Item & Inventory Cheats

Pokeball Modifier Cheats

Never run out of Pokeballs with these item modifier codes. Perfect for completing your Pokedex without the frustration of failed catches.

Unlimited Master Balls: 0101D1D2

Unlimited Ultra Balls: 0101D2D2

Unlimited Great Balls: 0101D0D2

Unlimited Poke Balls: 0101CED2

How to Use:

  1. Activate the desired Pokeball code
  2. Access your bag inventory
  3. Look for the corresponding Pokeball type
  4. You should see x99 or x999 quantity

Ball Effectiveness Guide:

  • Master Ball: 100% catch rate on any Pokemon
  • Ultra Ball: Best for regular Pokemon catching
  • Great Ball: Good mid-tier option
  • Poke Ball: Basic catching tool

Remember that different situations call for different balls. Even with unlimited supplies, strategic catching can be more rewarding than using Master Balls for every encounter.

Burn Heal: 0101D8D5

Ice Heal: 0101D9D5

Paralyze Heal: 0101D6D5

Activate any combination of these codes to get unlimited quantities of the corresponding healing items. They will appear in your bag’s medicine pocket.

Strategic Usage:

  • Full Restores heal all HP and status conditions
  • Max Revives bring fainted Pokemon back with full HP
  • Keep a variety for different situations

⚠️ Important: Some key items are story-critical. Getting them early can cause sequence breaks or prevent normal story progression. Use with caution and consider the impact on your gameplay experience.

TM and HM Modifier

Access all technical and hidden machines with these comprehensive codes. Perfect for building your ideal moveset without hunting for specific TMs throughout the game.

All TMs Code: 01631FD1

Popular TMs for Competitive Play:

  • Ice Beam: Essential for Dragon-types
  • Thunderbolt: Reliable Electric attack
  • Flamethrower: Consistent Fire damage

Troubleshooting Common Cheat Issues

Codes Not Working

When Pokemon Crystal cheats don’t work, it’s usually due to one of several common issues. Based on community feedback and testing, here are the most frequent causes and solutions.

Common Causes:

  1. Wrong Emulator Settings: Some emulators require specific cheat format settings. Ensure “GameShark” is selected as the cheat type, not Action Replay or Code Breaker.
  2. Game Version Mismatch: Pokemon Crystal has different versions (1.0, 1.1, 1.2). Some codes only work with specific versions.
  3. Code Format Issues: Codes must be entered exactly as shown, without spaces or extra characters.
  4. Conflicting Cheats: Some codes don’t work together. Try disabling other cheats before adding new ones.
  5. Emulator Compatibility: Not all emulators support all codes equally well.

Step-by-Step Troubleshooting:

  1. Verify code entry is exact (no typos)
  2. Check emulator cheat type settings
  3. Test with a simple, known-working code first
  4. Disable all other cheats
  5. Restart the game and emulator
  6. Try an alternative code if available
  7. Check online forums for emulator-specific issues

Testing Strategy: Start with the infinite money code (019973D5, 019974D5, 019975D5) as it’s one of the most reliable. If this works, your setup is correct, and other codes should work too.

Game Crashes and Freezes

Game crashes are the most serious cheat-related issue. Based on real user experiences, here’s how to prevent and recover from crashes.

Prevention Strategies:

  • Save Before Cheating: Always create a save state before activating new codes.
  • Test Codes Individually: Activate one code at a time to identify problematic ones.
  • Avoid Risky Combinations: Some codes conflict when used together.
  • Know Safe Zones: Some areas are more prone to crashes with cheats active.

High-Risk Situations:

  • Using walk through walls in unknown areas
  • Activating Pokemon modifiers during special events
  • Multiple stat or ability modifiers simultaneously
  • Cheats during cutscenes or story events
  • Entering areas with complex scripting

Recovery Steps:

  1. Force close the emulator
  2. Restart without cheats enabled
  3. Load your most recent save file
  4. Identify which cheat caused the crash
  5. Remove or replace the problematic code
  6. Test with safer alternatives

⚠️ Important: Some users report losing entire save files due to cheat-related crashes. Regular backups are essential. Copy your save file (.sav) to a safe location before experimenting with new codes.

Version Compatibility Issues

Different versions of Pokemon Crystal may require different cheat codes. Understanding version compatibility can save hours of frustration.

Version Identification:

  • Check the game title screen for version info
  • Look for “Rev 1” or “Rev 2” indicators
  • Some emulators show ROM information in settings
  • File names sometimes indicate version

Common Version Differences:

  • Japanese vs. International versions
  • Revision 1.0 vs. 1.1 vs. 1.2
  • Virtual Console vs. original ROM
  • Patched vs. unpatched versions

Alternative Codes for Different Versions:

  • Walk Through Walls: Try 0108D3CF or 0108D7CF
  • Master Balls: Try 0101D1D2 or 0101D0D2
  • Infinite Money: Try 3-line or single-line versions

Testing Method:

  1. Start with codes from this guide
  2. If they don’t work, search for version-specific alternatives
  3. Test alternative codes one by one
  4. Document which codes work for your version
  5. Share findings with the community

Save File Corruption

The most serious risk of using cheats is potential save file corruption. Based on community reports, here’s how to protect your progress.

Warning Signs:

  • Graphical glitches persisting after disabling cheats
  • Unable to access PC boxes or bag
  • Pokemon appearing as “?????” or with glitched sprites
  • Game crashes when loading save file
  • Story progression blocked or broken

Prevention Measures:

  1. Create multiple save files at different points
  2. Backup save files regularly (copy .sav files)
  3. Use save states in addition to regular saves
  4. Avoid cheats during critical story moments
  5. Test codes in less important areas first

Recovery Options:

  • Load an earlier save file
  • Use save states if available
  • Try loading with cheats disabled
  • Check for save file repair tools
  • Start a new game as last resort

✅ Time Saver: Set up automatic save file backups. Some emulators support this feature, or you can use system-level backup tools to protect your progress.

Frequently Asked Questions

Is it safe to use cheat codes in Pokémon Crystal?

Cheat codes are generally safe if used properly, but they carry risks including game crashes, save file corruption, and story progression issues. Always save before using cheats and create backups of your save files. Some cheats are safer than others – money and item cheats rarely cause issues, while complex modifiers can be problematic.

Why won’t my Pokémon Crystal cheats work?

Cheats might not work due to wrong emulator settings, incorrect game version, code formatting errors, conflicting cheats, or emulator compatibility issues. Ensure you’re using GameShark format, codes are entered exactly as shown, and your emulator supports cheat codes. Try testing with simple codes first to verify your setup works.

Can I use multiple cheats at once in Pokemon Crystal?

Yes, you can use multiple cheats simultaneously, but this increases the risk of conflicts and crashes. Start with one or two simple cheats to test compatibility. Avoid combining complex modifiers like Pokemon species changers with stat modifiers. If the game becomes unstable, disable codes one by one to identify the culprit.

How do I backup my Pokemon Crystal save file?

Locate your save file (usually .sav extension) in your emulator’s save directory and copy it to a safe location. Many emulators have built-in backup features. For mobile devices, use file manager apps to copy save files to cloud storage or SD cards. Regular backups are essential when using cheats.

Are GameShark codes different from Action Replay codes?

Yes, GameShark and Action Replay use different code formats and systems. Pokemon Crystal primarily uses GameShark codes. Ensure your emulator is set to GameShark mode, not Action Replay or Code Breaker. The codes in this guide are specifically formatted for GameShark devices and compatible emulators.

Why does my game crash when using cheats?

Game crashes from cheats usually occur due to conflicting codes, entering restricted areas, using codes during story events, or version incompatibilities. Walk through walls codes are particularly risky in unknown areas. Try using cheats in safe locations, avoid complex combinations, and ensure codes match your game version.

Final Recommendations

After testing dozens of Pokemon Crystal cheats across multiple emulators, I’ve found that starting simple and being cautious leads to the best experience. The infinite money and item modifier codes are the safest way to enhance your gameplay without risking save file corruption.

For the best overall experience, I recommend using the infinite money code (019973D5, 019974D5, 019975D5) combined with unlimited master balls (0101D1D2). This combination gives you the freedom to catch any Pokemon and buy any items without the grinding that makes retro Pokemon games time-consuming.

The best value for your time comes from the unlimited rare candy code (0120F6D5), which allows you to quickly level up your team for challenging battles or complete your Pokedex faster. Just remember that Pokemon trained exclusively with rare candies may have slightly weaker stats than those trained through battles.

Whether you’re a completionist wanting to catch every Pokemon, a casual player looking to skip grinding, or someone revisiting childhood memories, these Pokemon Crystal cheats can enhance your experience. Just remember to save often, backup your files, and enjoy this classic Game Boy Color title in a whole new way.
