Heart Gold Action Replay Cheats: Why We’re Still Using Them in 2026

Cheating in Pokémon feels different now. Back in the day, you’d shove a bulky plastic cartridge into your DS Lite and pray the contact pins didn't snap. Today, whether you’re on original hardware or a high-end emulator, the hunt for heart gold action replay cheats is basically a rite of passage for anyone revisiting Johto.

Grinding is a nightmare. Honestly, nobody has forty hours to spend headbutting trees just to find a Heracross with a decent nature. We use these codes because we love the game, but we value our sleep more.

The Essentials for Every Trainer

You’ve probably seen a million forum posts from 2010. Most of those codes still work, but finding the "clean" ones is the real trick. If you want the basics—Rare Candies and Master Balls—you usually need a Master Code first to get the game and the Action Replay talking to each other.

For the US version of HeartGold (Game ID: IPKE-4DFFBF91), the Max Money code is a classic. You press Select, and suddenly your wallet is hitting that 999,999 cap. It’s helpful for buying those expensive TMs in Goldenrod City without playing Voltorb Flip for three days straight.

1. Rare Candy Code (999 in Bag Slot 1): 94000130 FCFF0000
   B2111880 00000000
   E0000B74 000000A0
   03E70032 00000000
   D2000000 00000000

This specific string requires you to hold L and R. It’s a common trigger. Some people get annoyed because it overwrites whatever was in that first slot, so move your important stuff before you trigger it.

The Wild Pokémon Modifier Strategy

This is where things get kinda complicated. You don’t just enter a code and see a Mew. Usually, these codes work by giving you a specific number of items in your bag. If you have 493 Master Balls, the game thinks "Okay, the next encounter is Arceus."

It’s a clever bit of memory manipulation. Hackers like those over at Project Pokémon figured this out years ago. You discard items until the quantity matches the National Dex number of the Pokémon you want. It’s tedious. It’s manual. But it works every single time.

The Shiny Hunt Shortcut

Let’s talk about the Wild Pokémon Shiny Code. This is the one everyone wants.

(Shortened for brevity—always verify full hex strings)

Using this means every single encounter in the grass will sparkle. There’s a catch, though. Sometimes the Pokémon caught this way have "trash" IVs or weird personalities because the code forces the shiny PID (Personality ID). If you’re a purist, this might bother you. If you just want a red Gyarados… well, you already have one of those. If you want a golden Steelix, this is your best bet.

Broken Saves and Bad Eggs

You’ve heard the horror stories. Someone uses a "Walk Through Walls" code, saves in the middle of a mountain, and can’t move. Or they use an "All Badges" code too early and the game’s event flags get so tangled up that Professor Elm won't give them the Master Ball.

Bad Eggs are the real villain here.

A Bad Egg is basically a placeholder for corrupted data. If the Action Replay tries to generate a Pokémon that the game doesn't recognize (like a level 0 glitch mon), it turns into a Bad Egg. You can’t hatch them. You can’t release them. They just sit there in your PC like a digital paperweight, taking up space forever.

Never save immediately after using a new code. Check your PC first. Check your party. If everything looks stable, then you can commit to the save.

The Emulator vs. Hardware Reality

In 2026, most people aren't using the physical Action Replay hardware. Those things are expensive collectibles now. Most of us are on emulators or using a flashcart like an R4.

Emulators make this way easier. You just paste the hex code into a menu. No physical flickering or loose cartridges. If you're on a 3DS, you might be using TWiLight Menu++ or PKHeX. PKHeX isn't technically an Action Replay, but it’s a save editor that does the same thing more safely. Instead of injecting code while the game runs, you just change the file. It’s less likely to crash your game mid-battle.

Actionable Steps for a Clean Experience

If you're ready to jump back into Johto with a little extra help, follow this workflow to keep your save file from exploding:

• Backup Your Save: Whether it’s a .sav file on your SD card or a physical backup tool, do it now.
• One Code at a Time: Don't enable "Max Money," "Shiny Pokémon," and "Fast Hatch" all at once. The game’s RAM can only handle so much redirection before it chokes.
• The Mart Test: For item codes, always check a Poké Mart. If the shopkeeper’s menu is glitchy or the prices are $0, your code is likely for the wrong region (JAP vs US vs EU).
• Movement Warning: If you use the "Walk Through Walls" (R+B to enable), never save while standing on a tile that is normally inaccessible.

Using heart gold action replay cheats is about tailoring the experience. Maybe you just want to skip the Level 15 to 30 slog. Maybe you want to finally get that Celebi event that was locked away for decades. Whatever the reason, use the codes as a tool, not a way to break the game's logic entirely.

Keep a close eye on your party's stats after using a modifier. If things look "off," reboot without saving. It's the only way to stay safe in the long run.
