2. How to Use Cheats in Pokemon Leaf Green

Before you start entering cheat codes and unlocking all the cool extras, it’s important to know how to actually use them. The method depends on how you’re playing the game, whether on an emulator or original hardware like the Game Boy Advance (GBA). Let’s break it down step-by-step so you can start cheating like a pro.

Using Cheats on Emulators

Most players today use emulators to play Pokemon Leaf Green, and luckily, most emulators make it super easy to enter cheats.

On Mobile (e.g., My Boy for Android)

1. Open Pokemon Leaf Green in My Boy.
2. Tap the menu icon and select Cheats.
3. Tap the “+” icon to add a new cheat.
4. Enter the cheat code and give it a name (e.g., “Unlimited Money”).
5. Select the type of code (Game Shark, Code Breaker, etc.) depending on the cheat.
6. Tap “Enable” and go back to the game. Your cheat should now be active!

On PC (e.g., Visual Boy Advance)

1. Open your ROM in Visual Boy Advance.
2. Go to Cheats > Cheat List > Game shark/Code Breaker.
3. Paste the code and hit OK.
4. Some cheats require restarting the ROM save and reloading if needed.

Using Cheats on Real GBA Hardware

Using cheats on original GBA cartridges requires extra hardware like:

• Game Shark or
• Action Replay

You’ll insert the cheat device between the GBA and the game cartridge, then input the codes manually using the interface on the device. This method works, but it’s a bit clunkier than emulators and many codes are designed specifically for emulator compatibility these days.

Tips to Avoid Crashing or Glitches

• Only activate one or two cheats at a time stacking too many can cause the game to freeze.
• Save your game before activating a new cheat.
• Double-check if the cheat is Game Shark, Code Breaker, or Action Replay. Using the wrong format won’t work.
• Some cheats only activate in specific locations (like Pokemon modifiers in tall grass).

4. Troubleshooting Cheat Codes in Pokemon Leaf Green

Even though cheat codes can seriously boost your game, they can sometimes be tricky. If your cheats aren’t working or your game is acting up, don’t worry. It’s usually an easy fix. Here are some common issues and how to solve them.

1. Check the Cheat Type (Game Shark vs Code Breaker)

Not all cheats are created equal! Some are specifically designed for Game Shark, while others are Code Breaker or Action Replay. If you enter the wrong type, the code won’t do anything.

Pro Tip: Most item cheats (like Rare Candies) are Code Breaker codes, while battle effects (like walk-through-walls) are often Game Shark.

2. Restart the Game or Reload the ROM

Some cheats only activate after restarting the emulator or reloading your save file. Try saving your game, closing the emulator, then reopening it.

3. Enable Only a Few Cheats at Once

Running too many cheats can overload the game and cause:

• Freezing
• Glitches
• Crashes

Stick to one or two active cheats at a time, especially if you’re using an older emulator or ROM version.

4. Save Before Using a New Cheat

Always create a save state or in-game save before trying a new cheat. If something goes wrong, you can reload your game without losing progress.

5. Use a Clean ROM

If you’re using a modified or patched version of Pokemon Leaf Green, some cheats might not work. A clean, unmodified ROM is usually the most compatible for cheat codes.

6. Update or Switch Your Emulator

Some emulators (especially older versions) don’t support all types of cheat codes. Try using:

• My Boy (Android) – excellent cheat support
• Visual Boy Advance (PC) – very reliable
• mGBA (cross-platform) – updated and accurate

By following these tips, you’ll avoid the most common problems and enjoy a smooth, cheat-powered adventure through Kanto!

5. Conclusion

Cheat codes in Pokemon Leaf Green aren’t just about breaking the game. They’re about having a bit of fun, reliving childhood memories, and maybe skipping the grind when you’ve already played through the story a dozen times.

Whether you’re using Rare Candies to train your team faster, tossing unlimited Master Balls, or just walking through walls for the heck of it, cheats can add a whole new layer to the game. And hey, it’s your adventure you get to decide how to play it.

Just a quick tip before you go: save often, don’t overload your cheats, and if something feels off, disable the code and try again. Most issues are easy fixes, and once everything’s working, it’s smooth sailing from there.

So go ahead, load up your emulator, fire up those codes, and enjoy a fresh (and slightly overpowered) journey through Kanto. Have fun and happy gaming!
