You're standing in front of Rayquaza at the top of Sky Pillar, your fingers are sweating, and you've already burned through thirty Ultra Balls. It’s frustrating. We've all been there. Back in 2005, the grind was the point, but today? Most of us just want to mess around with the engine or finally catch that mythical Deoxys without flying to a Nintendo event in a city we don't live in. Pokemon emerald cheats aren't just about "winning"—they're about unlocking a twenty-year-old game that has a lot of its best content locked behind expired promotional events.
But here is the thing.
If you just go googling for a random list of hex codes, you are probably going to crash your save file. I’ve seen it happen a thousand times. Someone pastes a "Master Code" they found on a forum from 2008, walks through a door, and suddenly their character is stuck in a black void. It sucks. If you want to use cheats for Emerald properly, you have to understand the difference between GameShark, Action Replay, and CodeBreaker formats, and you absolutely need to know about the "DMA" issue that makes Emerald way more finicky than Ruby or Sapphire.
The Technical Headache: Why Emerald is Different
Basically, Pokemon Emerald uses something called Dynamic Memory Allocation (DMA). It sounds boring, but it's the reason your cheats often don't work. In the earlier Gen 3 games, the data for your items or Pokemon stayed in one spot in the RAM. In Emerald, that data moves around. This is why almost every cheat requires a "Master Code" (also known as an (M) code or Enable Code). This code tells the cheat engine where to look for the data that is constantly shifting. Without it, the cheat tries to write "99 Master Balls" into a memory slot that might currently be occupied by your rival's dialogue or the map’s music. That's how you get glitches.
Honestly, the most reliable way to play these days is via emulation (like mGBA) because it handles these hex overrides way more gracefully than a physical GameShark SP ever did.
Understanding the Big Three: GameShark vs. Action Replay vs. CodeBreaker
Most people think these are interchangeable. They aren't. A GameShark code is usually 12 digits long, while a CodeBreaker code is shorter, often 8 digits per line. If you try to put a CodeBreaker code into a GameShark menu on your emulator, nothing will happen. Or worse, the game will freeze the moment you hit "Start."
- GameShark V3/Action Replay: These use the same encryption. Most "modern" cheats you find online are in this format. They look like two blocks of eight characters.
- CodeBreaker: These are generally more stable for Emerald. They are "raw" codes. If you can find the CodeBreaker version of a cheat, use it. It's less likely to cause that weird screen flickering.
- The "Master Code" Necessity: For Emerald specifically, the Master Code must be the first thing you toggle on. If you turn on the "Wild Pokemon Modifier" before the Master Code, the game has a high chance of throwing a "blue screen" error or just deleting your bag.
How to Get Every Legendary Without the Events
The biggest draw for using pokemon emerald cheats is the "Event Tickets." Back in the day, you needed the Eon Ticket, the Aurora Ticket, and the Old Sea Map to get to Southern Island, Birth Island, and Faraway Island. Unless you have a time machine or a very specific distribution cartridge, you can't get these legally anymore.

You have two ways to do this. You can use a "Warp Code" which just teleports you to the island. Or, you can use a "Key Item" code to put the ticket in your bag and then talk to the NPC at the ferry in Lilycove.
The Warp Method is faster but riskier.
If you warp to Birth Island to catch Deoxys, you might find that the ferry doesn't work to take you back. You’re stuck. Always, and I mean always, have a Pokemon with Fly or a separate "Warp to Petalburg" code ready. Otherwise, that Deoxys is going to be your only friend in a very small, very lonely prison.
Catching the "Uncatchables"
Want a Mew? You need the Old Sea Map. In the Japanese version of Emerald, this was a standard giveaway. In the English version? It was never officially released. This means the only way to see the "legit" Mew event in an English Emerald ROM is to cheat the map into your inventory.
- Birth Island (Deoxys): Requires the Aurora Ticket.
- Navel Rock (Ho-Oh and Lugia): Requires the Mystic Ticket.
- Faraway Island (Mew): Requires the Old Sea Map.
There’s something surreal about walking through the tall grass on Faraway Island for the first time. It feels like a fever dream because it was "hidden" for so long.
The "Must-Have" Quality of Life Cheats
Let's be real: nobody likes grinding for EVs or breeding for 100 hours just to get a decent Nature. If you’re playing on an emulator, you're likely looking for these specific shortcuts.
Unlimited Rare Candies
This is the classic. It usually replaces the first item in your PC storage. A word of caution: if you use Rare Candies to level a Pokemon to 100, its stats will be lower than a Pokemon leveled through battling. This isn't a glitch; it's because the Pokemon isn't gaining Effort Values (EVs). You’ll have a Level 100 Rayquaza that hits like a Level 80 one.
The Master Ball Modifier
Similar to the Rare Candy cheat, this usually targets "Slot 1" of your bag. It is much safer than the "Catch Trainers Pokemon" cheat. Seriously, stay away from that one. Stealing a trainer's Pokemon often results in the game thinking you have 7 Pokemon in your party, which leads to immediate save data corruption.
Walking Through Walls (Ghost Mode)
This is the most fun, but the most dangerous. It allows you to bypass the scripted events. You can walk right past the guards, skip the puzzles in the Gyms, or even walk on water without Surf. But if you walk into a building and the game triggers a cutscene while you are standing on a tile where you shouldn't be, the game engine will loop and crash.
Dealing with the "Bad Egg"
If you've spent any time in the cheating scene, you've heard of the Bad Egg. It sounds like a creepypasta, but it’s a real mechanic.
The Bad Egg is basically a checksum error. When the game's internal security check realizes that a Pokemon's data has been modified incorrectly (like using a "Shiny" code that doesn't match the Pokemon's ID), it "bricks" that Pokemon to save the rest of the game data. It turns into an egg that will never hatch.
Can you get rid of it?
Not easily. You can't release it. You can't trade it. It just sits there in your PC, taking up space, a digital monument to a broken cheat code. The only real "fix" is using a save file editor like PKHeX on a computer to manually delete the hex strings for that slot. This is why you should always make a backup of your .sav file before you enter a single line of code.
Why Some Codes Simply Won't Work
You found a code. You typed it in perfectly. You turned it on. Nothing.
This usually happens because of Region Locking. Emerald had different builds for North America, Europe, and Japan. A code designed for the German version of Emerald likely won't work on the US version because the "offset"—the specific address in the memory where the data lives—is slightly different. If you’re using a ROM, check the internal header. Most codes you find online are for the (U) or (USA) version.
Another common culprit is the VBA-M vs. mGBA conflict. Older emulators like VisualBoyAdvance (VBA) used a specific way to handle "Cheat Lists" (.clt files). Newer emulators are more precise. If a code requires a "16-bit" write but the emulator is trying to do an "8-bit" write, the value won't change.
The "Shiny" Cheat Warning
Everyone wants a Shiny Charizard. The problem is that Emerald’s "Shiny" codes often work by forcing the game to re-roll the Pokemon's Personality Value (PV). This can sometimes change the Pokemon's Nature or its IVs (Individual Values). You might get a Shiny, but it might end up having the "Hasty" nature and terrible stats.
If you want a "perfect" Pokemon, you're better off using a tool like PKHeX. You take your save file, open it on your PC, and you can literally just click a button to make a Pokemon Shiny or change its moves. It’s much cleaner than using raw hex codes while the game is running.
Step-by-Step: Testing Your Codes Safely
Don't just dive in. Follow this sequence if you value your 40-hour save file.

- Save in-game first. Do not rely on "Save States" in your emulator. An actual in-game save (Start > Save) writes the data to the "SRAM."
- Backup that save. If you're on a phone or PC, copy the
.savfile to a different folder. - Enter the Master Code. Label it clearly.
- Enter ONE secondary code. Don't try to get "Infinite Money," "All Items," and "Walk Through Walls" all at once.
- Trigger the effect. Go into a battle or open your bag.
- Check for glitches. Look at your trainer card. Are the colors weird? Is the music stuttering? If yes, turn it off immediately without saving.
Actionable Next Steps for Emerald Players
If you're ready to start, start small. Don't go for the "National Dex Unlock" immediately. Start with something simple like the Infinite Money code so you can buy as many Revives as you want for the Elite Four.
- Download mGBA: It’s currently the most accurate emulator for handling GBA cheats without crashing.
- Locate "v3" GameShark Codes: These are the most widely documented for the US version of Emerald.
- Find the Master Code (M): Make sure it matches your specific ROM version (usually begins with
00006FA3 000A). - Use PKHeX for "Legal" Cheating: If you just want to fix a Nature or add an event item, using an external save editor is 100% safer than using active memory cheats.
The world of pokemon emerald cheats is deep, and while it’s tempting to turn yourself into a god-tier trainer in five seconds, the real joy is using these tools to see the parts of the game Nintendo "hid" from us twenty years ago. Just remember to back up your save, or you'll be starting your journey back in Littleroot Town sooner than you think.
Resources and Verification:
For those looking for the raw hex strings, the most verified databases remain the Project Pokémon forums and the archival sections of Bulbagarden. These communities have spent decades deconstructing the Gen 3 engine, and their "Master Code" lists are generally considered the gold standard for avoiding save corruption. Avoid "cheat-generator" websites that look like they were made in 2004; they often host broken or "dirty" codes that aren't properly terminated.
