How to Redeem and Use Cheat Codes

You cannot enter these codes natively into Pokémon Crystal. They require a third-party device or emulator software.

• For Original Hardware (Game Boy Color): You need a physical GameShark device. Plug the GameShark into your console, insert the Pokémon Crystal cartridge, and enter the codes into the GameShark menu before booting the game.
• For Emulators (mGBA, VisualBoyAdvance): This is the most common and accessible method. Open the cheat code function in your emulator (usually under “Cheats” or “Gameshark”), create a new code, and paste the full code string exactly as written.
• Activate and Test: Enable the cheat code and start your game. For safety, test the code’s effect immediately. If it causes issues, disable it and reload a save.
• Important Safety Protocol: Always create a backup save file before activating any cheat. Furthermore, avoid activating multiple complex cheats simultaneously, as this dramatically increases the risk of game crashes or save file corruption.

Best Practices and Common Mistakes

Understanding how to cheat safely is as important as knowing the codes. A proactive approach prevents frustration.

Firstly, always test code in a controlled manner. Activate one cheat at a time to isolate its effect and ensure stability. If a code does not work, a common fix is to try changing the first digit of each line 9 to 0, or vice versa.

Secondly, respect the game’s limits. The “Walk Through Walls” code is notoriously unstable. Avoid using it in complex areas like caves or gyms. For inventory codes, consider that having 99 of every item can sometimes cause menu lag.

Ultimately, cheats are best for experimentation or a second playthrough. Using them to bypass the entire game’s challenge can ruin the experience. Many players find the most enjoyment in using cheats for specific goals, like completing the Pokédex with the “Catch Any Pokémon” code, rather than for universal domination.

FAQs

Are these cheat codes legal to use?

Using cheat codes on a personal copy of the game you own, either on original hardware or via a legally owned ROM, is generally acceptable for private play. However, using cheats in official competitions or in online fan tournaments is almost always prohibited.

Will using these cheats damage my game save?

They can. While many codes are safe when used correctly, there is always a risk of glitches or corruption. This is why creating a backup save before using any cheat is the single most important step you can take.

Why isn’t my cheat code working?

The most common reasons are an incorrect ROM version, a mistyped code, or emulator compatibility issues. Ensure your codes are for the original “Pokémon Crystal Version (USA, Europe)” ROM. Double-check each character, and try the 9/0 The digit swap trick is mentioned in the troubleshooting guide.

Can I use these codes on the Nintendo 3DS Virtual Console version?

No. The GameShark codes listed here only work on the original Game Boy Color game or its ROMs played on emulators. The Nintendo 3DS Virtual Console release does not support this form of code injection.

What’s the difference between a cheat code and a glitch, like the MissingNo. glitch?

Cheat codes are active modifications you apply externally via a device like a GameShark. Glitches are unintended bugs within the game’s own programming that can be triggered by specific in-game actions. Cheat codes are typically more powerful but carry a higher risk of destabilizing your game.
