How to Fix Not Working and Glitchy Cheats for Pokemon GBA Games

211

Activating GameShark code cheats for Pokemon Game Boy Advance games can sometimes be tricky. Some of our readers complain that our listed GameShark codes don’t work for them, while some said it works, but some weird glitches are happening.

What could be the main reasons for this? In my over eight and counting years of experience playing different Pokemon game titles and ROM hacks using other emulators across several devices, there several possible reasons why particular cheat cannot work.

Reasons Why Cheats Don’t Work as Expected and How To Fix Them

Gameshark code not working fix

Note: This article applies to Pokemon GBA games but can also be used to other related games on Game Boy Advance.

You forgot to enter and activate the master code

Solution: Some cheats need to have a master code enabled before the main cheat, so when a cheat requires master code, add it first before the main cheat. More information you can find by reading this guide.

The Cheat Isn’t Compatible with your Pokemon Game Version

Solution: Double-check your game title. See our collection of Pokemon game cheats.

You Have 1.1 ROM Version

Solution: Look for the V1.0 ROMs, as this version supports most of the cheats. You can easily find downloadable ROMS by a simple Google search, but most ROMs have version 1.1. Unfortunately, most cheats will not work for this version. Please keep in mind that we don’t share rom files or give out information about roms. Sharing rom files is considered piracy.

Your Emulator Does Not Support GameShark Code, Action Replay, or CodeBreaker

Solution: Use recommended emulators such as My Boy for Android users, Visual Boy Advance for Windows (Use this version), GBA4iOS for iOS users, and BlueStacks or Nox App Player for Mac users.

You entered the cheat code in a wrong format

Solution: Some emulator, such as open emu, requires “+” to be entered to separate a line of code. Read FAQs, Instructions, and Help articles regarding your emulator.

You Have the Free version of Emulator

Solution: The popular GBA emulator for Android – My Boy, offers a paid and free version of the app. The free version works perfectly, but you may need to pay for the premium version if you use cheats. But if paying for the app is not an option now, the simple trick of adding multiple-liner codes as a separate cheat works well in many cases.

Too Many Enabled Cheats

Your ROM will get confused when too many cheat codes are activated at once, and this could result in various bugs, glitches, random crashing, and game freezing.
Solution: Disable unused cheats and activate only the cheat you need.

You Have Chosen the Wrong Cheat Type

This problem is prevalent in emulators that don’t have “auto cheat type” detection feature, and chances are, you have chosen the wrong cheat type. The quick solution for this is knowing the appropriate type for your cheat; it could be GameShark, Action Replay, or Code Breaker.

Question Mark Sprite on Encountered or Caught Pokemon?

A common issue with two possible reasons; First, more likely that you entered the wrong Pokemon encounter code. Second, the Pokemon code and sprite don’t exist in the game. This issue happens a lot when playing ROM hacks. Solution? Double-check if the code or the Pokemon exists in the game.

Glitchy Name for Captured Pokemon

This bug usually happens when using the shiny Pokemon cheat, and the possible reason it occurs is that cheating is not fully supported in Pokemon GBA games. But there is an effective fix for this problem that has been tested for many players.

Solution: To fix the glitchy Pokemon name, you must disable the shiny cheat just before capturing a Pokemon.

Invalid Cheat Message

There are three possible reasons why this error message pops up.

  • Wrong cheat type
  • Wrong cheat code
  • Empty spaces before or after the code

Solution: Select the correct type for that cheat; the majority of cheats are either CodeBreaker or Action Replay codes type, so if the first one didn’t work out, switch to the other one.

Be sure to check the cheat if it is compatible with your game version. For FireRed-based rom hacks, typical FireRed cheats could work, and for Emerald-based rom hacks, regular Emerald cheats could also work.

Empty spaces could also result in an invalid cheat issue. When copying a cheat, make sure not to include empty spaces. When entering the cheat, make sure to eliminate any empty spaces before and after the code.

Conclusion

It’s frustrating when you can’t activate a cheat, and there are plenty of reasons why this thing is happening. Hopefully, the solution and information above give you the insights to finally solve your problem.

I have an issue, I use VBA on mac OS Monterey and I’m having trouble using the rare candy and other PC related cheats. I’m just fine using overworld and encounter based cheats but I can’t do anything with my PC. Do you have any suggestions or fixes for them.

Hi. I’m new to both emulators and cheats. I have pizza boy pro playing unbound 2.1.0. Not generally a fan of heavy cheat usage, but I’m trying to just get a couple of things, like a fire stone and link stone. I’ve looked up codes specific to my game and version, using a master code and an item code. I’ve tried game shark, code breaker etc. When i go to the pokemart to buy the item, it slightly glitches the name of the first item, but doesn’t make the change to a stone.
Any ideas?

I used the Rare candies in the pc cheat, it worked, but it cannot be withdrawn.
Tried, turning off/on the cheat, restart the emulator/game, still the same thing.
I use VBA -M 2.0.1

I used cheats and now I can’t catch any Pokemon it shows it dodged the ball and it can’t be caught and i disabled the cheats also but still its not working help me please.

It’s also frustrating when the person writing the solutions to the problems you’re experiencing aren’t being specific.

Hello. May i get a download link of Pokémon FireRed V1.0?

I used the cheat for move tutor for a while I stopped paying for like a few months I come back and it doesnt work anymore how do I fix this?

When I look at the cheats folder on my emulator, the files typing is “AutoCAD Dictionary”. I thought maybe that has something to do why it’s not working. Could that be the case?

Hi, I’ve found that my John GBA emulator doesn’t recognize CodeBreaker codes starting by 0 (0xxxxxxx yyyy) do you people know any way to input these codes?

MyBoy user Pokemon Fire Red 1.1v So I’ve used the “all pokeballs” “rare candy” and “$1 pokeshop” cheats not sure which caused my issue but now anytime I open my TM case its all gibberish. Now I can scroll up and down the list and it gets worse as I go down and starts to overlap, the moment I try to exit it out of the TM Case, the game freezes and I either reset the game through the menu option or just close the app entirely.

Hi! I used the cheat for getting all the state pokemon, and it worked! I’m using the free version for Pokemon gold.

Hi, may I ask question that not really related on this context?
I have a problem with Drayano Pokemon Blaze Black 2 Ver. 1.1
The only problem is, when I entered the Giant Chasm, Drayano mentioned “after battling/catching Kyurem, you will meet a veteran inside there”. The result, no one is there

Perhaps you know the problem? Because I only use 2 cheats simultaneously (exp + money multiplier) and accidentally using super repel before entering the cave.

I’m so sorry if this question out of context somehow

I’m playing Pokemon Sweet Version (Fire Red hack), and i’m using the Squirrels version of Fire Red. But whenever I enter the shiny code, i get a glitch name, whether I turn off the code or not, or the game just freezes. i KNOW it’s possible to get shinies via a code, i just don’t know how. Help, please?

yes, i tried. I’m playing it on VBA, and it’s just not working. My Windows version is Windows 10, if that helps any.

Okay, so I was having the naming glitch with the shiny Pokemon so I did as suggested and disabled right before capture. However, when I evolved the Pokemon the appearance was all glitchy and didn’t display properly. Is there a fix for that?

I switched to mGBA from OpenEmu at your recommendation and it does seem to be better for cheats. I was able to get some working that I previously wasn’t getting so thanks! I’m not having a weird issue where I’ll add the Wild Encounter Mastercode, then I’ll add a second code for the pokemon I want and enter in 3 lines of code (2 for First Code last line for the pokemon I want), but when I look at the code after it’s entered the first code of the lines of the First Code is always missing and of course… Read more »

^Unfortunate typo: it should read “I’m now* having a weird issue…”

It keeps deleting one line of code as soon as I enter it. Any ideas of what I’m doing wrong?

I’m having the same problem… I ended up entering the code under “Add CodeBreaker” and it saved all the lines of code, but I’m still having problems with getting the Wild Pokemon I want to appear.

Is there any solution yet? I’m having the same problem too

So in other words “if you’re having issues its YOU or YOUR rom” this didn’t give me any information on how to FIX tyr problem… On emerald I take your codes, copy paste them, pick GS, GSV3 or CB and all give the same answer, CODE invalid
