You're standing in front of Mewtwo in Cerulean Cave. Your palms are sweaty. You've burned through thirty Ultra Balls and the psychic powerhouse just recovered its health for the fifth time. We've all been there. Whether it's the grind of leveling up a Dratini to level 55 or the sheer frustration of trying to find a shiny Ponyta, sometimes the "intended" way to play Pokémon Fire Red feels more like a second job than a hobby. That's exactly why pokemon fire red action replay codes became the playground legend of the mid-2000s.
But here's the thing. Most of the lists you find online today are messy. They're copied and pasted from 2005 forums, filled with dead codes that cause the dreaded "Blue Screen of Death" on your emulator or freeze your physical Game Boy Advance. If you're going to use them, you've gotta do it right.
The Master Code: Your Mandatory First Step
Before you even think about infinite Rare Candies or walking through walls, you have to talk about the Master Code (m). Think of it as the handshake between your cheat engine and the game's ROM. Without it, the game won't recognize that you're trying to inject new data into its memory.
For most versions of Fire Red (specifically the v1.0 English version), the Master Code is:72BC6DFB E9CA5465A47FB2DC 1AF3CA86
You enter this first. Every time. No exceptions. If you try to run a cheat without this active, your game will likely just hang on a white screen. It’s a safety protocol.
Why People Still Use Pokemon Fire Red Action Replay Codes Today
Why are we still talking about a game released in 2004? Because Fire Red and Leaf Green remain the gold standard for the Kanto experience. They have a certain "snappiness" that the modern 3D games lack. However, they are also products of their time.
The grind is real.
If you want a competitive team to take on the Elite Four's second round—where their levels jump into the 70s—you're looking at hours of beating up wild Sevii Island Pokémon. Action Replay codes aren't just for "cheating" in the sense of making the game trivial; they’re often used as time-savers. Most adult players today don't have forty hours to spend on the Victory Road grind. We just want to get to the good stuff.
The "Big Three" Codes Everyone Actually Wants
Most players are looking for three specific things: items, money, and encounters. Let's break down how these actually function in the game's hex code.
1. Infinite Rare Candies
This is the holy grail. Instead of farming, you just feed your Charizard until it hits level 100. The code usually replaces the first slot in your PC storage.82025840 0044
Once you toggle this on, check your PC (not your bag). You’ll see a Rare Candy with a "x99" or a glitched quantity. Withdraw one, and it stays at 99. It’s basically a bottomless well of sugary level-ups.
2. The Master Ball Glitch
Catching legendary birds shouldn't take three hours. The code 82025840 0001 puts Master Balls in your PC. Honestly, use these sparingly. Part of the fun of Pokémon is the tension of the catch, but for roaming legendaries like Entei or Raikou? Yeah, just use the Master Ball. Life is too short to chase a digital dog across the entire Kanto region for three weeks.
3. Infinite Cash
The code 29C78059 96A91A40 maxes out your wallet. This is probably the safest code to use because it doesn't mess with your inventory slots or Pokémon data. It just changes a single value in your trainer's save file.

The Danger Zone: Walking Through Walls and Wild Encounters
Here is where things get dicey. The "Walk Through Walls" code (5091951A 8A3AABBD) is legendary. It lets you skip the S.S. Anne, bypass the guards who want tea, and go straight to the end of the game.
But be careful.
The game triggers events based on "step triggers." If you walk through a wall and miss a trigger for a rival battle or a key item giveaway, you can soft-lock your save file. You might find yourself in the Hall of Fame without the National Dex, and suddenly, the post-game content is locked forever because the game thinks you haven't finished the main quest. If you use this, save your game before you turn it on, and keep a backup.
Wild Pokémon Encounters
Want a Mew or a Celebi? You can force the game to generate them.
- Mew:
17543C48 3034AB3F - Deoxys:
C8660348 DC2B992D
You usually have to pair these with an "Enabler" code specific to the Pokémon species. Just remember that Pokémon caught this way often won't obey you if you don't have the right gym badges, and they definitely won't pass "legitimacy checks" if you try to migrate them to later generations through Pal Park.
How to Avoid Corruption
I've seen so many people lose 50-hour save files because they got greedy. They'd turn on fifteen codes at once. Don't do that. The GBA's processor is ancient. It can't handle multiple memory overrides simultaneously.
Follow these rules of thumb:
- One at a time. Turn on the Master Ball code, get your balls, save the game, and turn the code off.
- Don't save while "Walk Through Walls" is active. Walk to where you need to go, step onto a "legal" tile, turn the code off, verify the game isn't crashing, then save.
- Check your version. Most codes are for the 1.0 version. if you have the 1.1 version (which fixed some minor bugs), many of these addresses will be shifted by a few bytes, causing the game to crash.
The Ethics of Cheating in a Single-Player Game
Is it "wrong" to use pokemon fire red action replay codes? Some purists will say yes. They'll talk about the "sanctity of the grind." Honestly, though, it's a twenty-year-old game. If you've already played it ten times and you just want to experiment with a team of six Tyranitars from the start of the game, go for it.
The only time it becomes a problem is in the competitive scene. Using codes to generate "illegal" Pokémon for tournaments is a big no-no. But for your own enjoyment on a rainy Tuesday? It’s your game. Play it how you want.
Troubleshooting Common Issues
If your codes aren't working, check your emulator settings. If you're using mGBA or VisualBoyAdvance, make sure the cheat type is set to "Action Replay" and not "CodeBreaker" or "GameShark." They use different logic.
Also, watch out for "Anti-DMA" codes. Some versions of Fire Red use Dynamic Memory Allocation, which moves data around to prevent exactly what we're trying to do. If your codes work once and then stop, you probably need an Anti-DMA master code to lock those memory addresses in place.
Step-by-Step Recovery Plan
If your game starts glitching out after using a code, don't panic.
- Immediately turn off all cheats in the menu.
- Try to enter a building (this forces the game to reload the map data).
- Check your party. If you see a "Bad Egg," do not save. A Bad Egg is the game's way of saying "you corrupted the checksum of this Pokémon's data." If you save with a Bad Egg, it can spread or permanently take up a slot in your PC.
- If things are still weird, restart from your last "hard save" (the in-game save menu, not a save state).
Using these codes is a bit like modding a classic car. It’s powerful and cool, but if you don't know where the oil goes, you’re going to smoke the engine. Stick to the item codes first, move to encounter codes next, and only use the "world-bending" codes like Walk Through Walls when you have a backup save ready.
To get started safely, your first move should be to identify exactly which version of the ROM you're running. Look at the title screen or the file name; if it doesn't specify v1.1, it's almost certainly v1.0. Start by activating only the Master Code and the Infinite Money code to verify that your setup is working correctly before moving on to more complex character or item overrides. Once you've confirmed the money code has updated your trainer card, you'll know your Action Replay engine is successfully hooked into the game's memory.
