Pokemon HG Action Replay Codes: What Most People Get Wrong

Pokemon HG Action Replay Codes: What Most People Get Wrong

You’re staring at Red on top of Mt. Silver, and your Typhlosion is barely hanging on. Maybe you’ve spent forty hours grinding in the tall grass just to get a single Rare Candy. It’s exhausting. We've all been there, and honestly, that's why pokemon hg action replay codes are still a thing in 2026.

Back in the day, you had to own a physical Action Replay dongle that felt like it was going to snap your DS cartridge slot. Nowadays, whether you're on original hardware or firing up an emulator like Delta or DeSmuMe, the game remains the same. But here's the kicker: people still mess up the activation triggers. You can't just paste a code and hope for the best. Most of these require a specific "handshake," usually pressing L+R or Select at the right screen to actually inject the data into the RAM.

The Codes Everyone Is Actually Looking For

Let’s be real. You aren’t here for "Infinite Repels." You want the heavy hitters. You want the stuff that saves you a hundred hours of your life.

Rare Candy and Master Balls (The "Big Two")

If you want 999 Rare Candies, you usually need to use the Medicine pocket modifier. In HeartGold, the common code structure targets the first few slots of your bag.

Rare Candy Code (Press L+R):
94000130 FCFF0000
B2111880 00000000
E0000B74 000000A0
03E70032 00000000
D2000000 00000000

For Master Balls, it’s a similar story. Most people prefer the code that gives you 999 in your Ball pocket.
94000130 FFBB0000
62111880 00000000
B2111880 00000000
D5000000 03DE0001
C0000000 0000000F
D6000000 00000D14
D4000000 00000001
D2000000 00000000

Why Your Codes Keep Crashing the Game

I've seen so many forum posts from people complaining that their save file got "corrupted." Sorta. Usually, it’s not that the save is gone, it’s that the bag data is scrambled.

If you use a code to get "All TMs" and then try to use a code to get "All Medicine" at the same time, the game might have a stroke. HeartGold is a 2010 game. It wasn't built to handle someone rewriting four different memory addresses simultaneously.

The biggest mistake? Activating codes while inside a building or a PokeMart. Always activate your codes while standing in the middle of a route or a town, then check your bag. If you do it inside a shop, the game is already trying to load the shop’s inventory list, and you’re basically trying to write two different lists to the same spot. It’s a recipe for a frozen screen.

The "Shiny" Problem

Shiny codes are notoriously finicky. There are two types: one that makes wild encounters shiny and one that modifies the Pokemon already in your party. The wild encounter one is safer.

Wild Shiny Pokemon Code:
621D1584 00000000
0206DEFC 47004800
0206DF00 02000001
E2000000 0000003C
6800480D 490B6840
88011808 9C0D8842
40510C24 20074061
04244041 940D430C
21001C28 F06EAA0D
4801FEA3 46C04700
0206DF05 000000DC

Kinda long, right? That’s because it’s literally rewriting how the game generates the "PID" (Pokemon ID) for every encounter. If you leave this on while trying to catch a legendary, be careful. Sometimes it can mess with the fixed IVs of legendary encounters like Lugia or Ho-Oh.

Specific Modifiers You Didn't Know You Needed

There are a few "quality of life" codes that aren't about cheating as much as they are about fixing the game's original annoyances.

  1. Walk Through Walls: Press R+B to enable, L+B to disable. Great for when you get stuck or just want to skip the Ice Path (because let's be honest, everyone hates the Ice Path).
  2. Instant Text: Because clicking through dialogue for the tenth time is a chore.
  3. National Dex Unlocked: Useful if you want to trade in a Pokemon from Sinnoh before beating the Elite Four.

Pro Tip: If you're using a physical Action Replay card, keep the pins clean. I know it sounds old-school, but a tiny bit of dust on the DS pins can cause the code to "drop" halfway through injection, which is what actually causes those weird "bad egg" glitches.

The Walkthrough Walls Trick

This is the one that lets you literally walk over the trees and water. It's legendary.
94000130 FCFD0200
1205DAA2 00000200
D2000000 00000000
94000130 FCFD0100
1205DAA2 00001C20
D2000000 00000000

You hold R+B and suddenly the collision detection just... disappears. Just don't save your game while you're standing in the middle of a mountain. If you turn the code off while you're inside a wall, you're stuck there forever unless you have a Pokemon with Fly or Teleport.

Actionable Steps for Safe Cheating

If you want to use pokemon hg action replay codes without ruining your childhood save file, follow this ritual. It sounds paranoid, but it works.

  • Save twice before entering any code.
  • Turn on only one code at a time. Do you want 999 Master Balls? Fine. Get them, save the game, turn the cheat off, and then move on to the next one.
  • If you’re on an emulator, use Save States. This is your safety net. If the bag glitches out, you just rewind ten seconds.
  • Check the "Game ID." For the US version of HeartGold, it’s usually IPKE-4DFFBF91. If your codes aren't working, you probably have a European or Japanese ROM, and those codes are completely different.

Honestly, the best way to enjoy these codes is to use them for the grindy stuff. Give yourself the Rare Candies so you can actually try out different teams instead of sticking with the same six Pokemon for the whole game because you're too tired to level up a new one.

The next thing you should do is verify your game's region in the emulator settings to ensure you aren't pasting US codes into a European ROM, as that's the most common reason for a black screen on startup.
