Pokémon HeartGold Cheats: Action Replay Codes for Nintendo DS

Pokémon HeartGold Cheats: Action Replay Codes for Nintendo DS

Table of Contents

By Robert Ryan for Pokemon Joy

Pokémon HeartGold cheats give players quick ways to adjust a Pokémon HeartGold playthrough with Action Replay codes for items, money, EXP, encounters, Shiny Pokémon, and other game features. The most important detail is matching the code to your HeartGold version and using the correct activation button. Current 2026 code references still list working options for popular emulators and US/EU ROM versions.

Pokémon HeartGold Version and Pokémon SoulSilver Version are enhanced Nintendo DS versions of the original Pokémon Gold and Silver games. They return players to the Johto region while adding updated graphics, sound, touch-screen controls, and the Pokéwalker accessory.

Quick note: Action Replay codes can change game data directly. Save your progress before experimenting, use one cheat at a time when possible, and keep a clean save available.

999 Rare Candy Cheat for Pokémon HeartGold

The pokemon heartgold rare candy cheat is one of the most searched options because Rare Candies provide a simple way to level a team.

Pokémon HeartGold Rare Candy Cheat Code

94000130 FCFF0000

B2111880 00000000

00000B74 03E70032

D2000000 00000000

Activation: Press L + R.

The current verified code reference lists this as an x999 Rare Candies in Bag code.

The pokemon heartgold rare candy cheat code is especially useful when you want to prepare a team for the later gyms, Elite Four, or post-game content while spending less time on ordinary grinding.

A good approach is to activate the code, confirm the Rare Candies appear, then disable the cheat before continuing your normal adventure.

Max Money Cheat

An unlimited money shortcut can make it easier to stock up on healing items, Poké Balls, battle supplies, and other useful purchases.

Max Money Action Replay Code

94000130 FCFF0000

62111880 00000000

B2111880 00000000

00000088 000F423F

D2000000 00000000

Activation: Press L + R.

A second version is available in current code references when the first activation method behaves differently:

94000130 FFFB0000

62111880 00000000

B2111880 00000000

00000088 000F423F

D2000000 00000000

The code source identifies both as money options.

This is one of the more practical heartgold cheat codes because it supports normal gameplay instead of changing Pokémon data.

All Poké Balls and Battle Items

Players looking for a pokemon heartgold all items cheat often want access to Poké Balls, healing supplies, battle items, TMs, HMs, and other inventory options.

The current verified list includes separate codes for all Poké Balls and battle items.

All Battle Items

94000130 FCFF0000

62111880 00000000

B2111880 00000000

D5000000 03840037

C0000000 0000000E

D6000000 00000D74

D4000000 00000001

D2000000 00000000

Activation: Press L + R.

For players searching pokemon heartgold rom cheat codes, pokemon heart gold rom cheats, or pokemon heartgold rom cheats, the important distinction is that a ROM is simply the game data being run by an emulator or another compatible setup. The cheat itself still needs to match the game version and code format.

All TMs and HMs Cheat

The pokemon heartgold all items cheat search often overlaps with requests for TMs and HMs.

One current code option uses Select + Up:

94000130 FFBB0000

62111880 00000000

B2111880 00000000

D5000000 00630148

C0000000 00000063

D6000000 000009B0

D4000000 00000001

D2000000 00000000

The verified reference provides two versions of the All TMs/HMs cheat and specifies Select + Up as the activation combination.

A related code allows Pokémon to learn all TMs and HMs:

920722C6 0000D001

120722C6 000046C0

D2000000 00000000

This type of cheat can be useful for testing movesets, experimenting with team builds, or exploring different options during a replay.

Walk Through Walls Cheat

The walk through walls cheat is one of the classic Pokémon HeartGold Action Replay options.

Walk Through Walls Code

9205DAA2 00000200

1205DAA2 00001C20

D2000000 00000000

94000130 FDFF0000

9205DAA2 00001C20

1205DAA2 00000200

D2000000 00000000

Activation: Hold L.

This code is currently listed among the verified HeartGold cheats.

Older community references also document a North American version that uses R + B to enable and L + B to disable.

Because movement cheats can place your character in unusual map positions, keep a backup save before experimenting. A useful rule is to use the code for movement and then return to ordinary gameplay before saving important progress.

Shiny Pokémon Cheat

Shiny Pokémon Cheat

The shiny pokemon option changes wild encounters so that Pokémon appear Shiny.

A current HeartGold reference lists this as a verified wild Shiny option and specifically marks it with a breeding warning.

That warning matters because a Shiny encounter modification can affect Pokémon data in ways that are different from simply obtaining a normally generated Shiny Pokémon.

The safer workflow is:

  1. Save your game first.
  2. Enable the Shiny cheat.
  3. Catch the Pokémon you want.
  4. Disable the cheat.
  5. Check the Pokémon in your party or PC.
  6. Continue playing from the clean state.

The shiny Pokémon concept is especially popular because HeartGold sits within the wider Pokémon video game series, where Shiny hunting became a major part of the collecting experience.

Wild Pokémon Modifier

A wild Pokémon modifier lets you replace the species that appears during wild encounters.

The current code format uses an identifier in place of AAA:

52247D8C 582000C0

12247D8A 00004801

02247D8C E0021C39

02247D90 00000AAA

D2000000 00000000

The reference provides a long species-ID table. For example, Bulbasaur is 001, Pikachu is 019, Chikorita is 098, Cyndaquil is 09B, Totodile is 09E, Lugia is 0F9, Ho-Oh is 0FA, and Celebi is 0FB.

This is useful when searching for pokemon hgss cheats, pokemon hg cheats, or pokemon heartgold generations cheats because many of these searches are really asking for encounter modifiers rather than ordinary item codes.

Why wild modifiers need extra care

Wild Pokémon modifiers can affect more than the species you see. The supplied competitor questions also show recurring reader concerns about Shiny combinations, breeding, emulator compatibility, and game behavior after changing encounters.

For that reason, keep encounter cheats separate from breeding and other Pokémon-generation modifications.

EXP Cheats

HeartGold also has Action Replay options for faster exp gain.

100× EXP

The current verified list provides a 100× experience option activated by holding R after a battle.

A 200× version is also listed.

These cheats can speed up team building while keeping the normal battle loop intact. They are especially convenient when preparing several Pokémon for a gym leader, the Elite Four, or later Kanto content.

An exp share can still be useful for normal progression, while an EXP cheat is more suitable for players who want a faster replay pace.

No Random Battles

HeartGold’s wild encounters are part of the normal adventure through the Johto region, but repeated encounters can slow down exploration.

A current verified list includes a No Random Battle (Outside) option:

A4000130 FFFC0000

62111880 00000000

B2111880 00000000

20025A54 00000000

D2000000 00000000

This type of pokemon cheat works well as a quality-of-life option when you are traveling through familiar areas such as Ecruteak City or exploring locations such as the Ruins of Alph.

Restore Health and One-Hit Battle Options

Some pokemon heartgold cheat codes focus on battles.

The current verified collection includes a Restore Health code and a 1-Hit Kills Pokémon code. The latter uses Select as its activation button.

These codes can speed up battles, while a restore-health option can provide a quick way to refresh a team during testing.

For ordinary play, utility cheats such as EXP, money, and items tend to preserve more of the game’s original battle flow.

Catch Pokémon With a Higher Catch Rate

A current HeartGold code list also includes options for easier capture and for catching another trainer’s Pokémon.

The capture-related codes include:

9224670A 00002101

1224670A 00002100

D2000000 00000000

Because these codes alter the normal capture rules, they are best treated as optional testing tools.

They can be useful when exploring the Pokédex, preparing a team, or experimenting with legendary Pokémon.

Pokémon Heart Gold Cheats for Emulators

Pokémon Heart Gold Cheats for Emulators

The phrase “Pokemon Heart Gold cheats emulator” usually refers to entering Action Replay-style codes through an emulator’s built-in cheat manager.

The exact steps depend on the emulator, but the basic workflow is similar:

  1. Start your Pokémon HeartGold game.
  2. Confirm your ROM region.
  3. Open the emulator’s cheat menu.
  4. Create a new Action Replay code.
  5. Paste the complete code.
  6. Give the cheat a clear name.
  7. Enable the code.
  8. Return to the game.
  9. Use the required button combination.
  10. Confirm the result.
  11. Disable the code after use when appropriate.

Current 2026 references specifically report testing HeartGold codes on DeSmuME and Delta for iOS, while other code collections also discuss emulator use.

Pokémon HeartGold Cheats on Delta

For Pokémon HeartGold cheats, Delta, the most important step is entering the complete code in the emulator’s cheat system and assigning the correct activation buttons.

Button mappings can vary between setups, so the physical L, R, Select, or other buttons may correspond to different keyboard or controller inputs.

Pokémon HeartGold Cheats on Other Emulators

The same principle applies to Pokémon Heartgold cheats emulator searches involving DeSmuME, DraStic, melonDS, or other Nintendo DS emulators.

If a code uses L + R, make sure the emulator recognizes those inputs correctly.

If a code uses Select + Up, verify that both inputs are mapped to the correct controls.

Current code documentation specifically points to button mapping as one reason a cheat can behave differently between emulator setups.

Pokémon HeartGold ROM Cheats and Version Matching

Pokemon HeartGold ROM Cheats and Version Matching

A major reason a Pokémon HeartGold cheat code may behave differently is the ROM region.

Current HeartGold cheat references separate codes by region, including US and EU versions.

Before using a code, check:

  • HeartGold or SoulSilver
  • US, EU, or another regional release
  • English or another language version
  • Original game or rom hack
  • Emulator and version
  • Correct Action Replay format

This is especially important for pokemon heartgold version cheats.

A code made for one revision can produce a different result when used with another game build.

The same point applies to pokemon heartgold rom cheats, pokemon heart gold rom cheats, and pokemon heartgold rom cheat codes. The ROM itself needs to match the code’s expected version.

Pokémon HeartGold Action Replay Codes vs. Normal Cheats

Action Replay is the main code format associated with Nintendo DS cheat databases.

The Nintendo DS is the original hardware platform for Pokémon HeartGold, and Action Replay codes work by modifying values while the game is running.

That is different from a normal in-game feature.

For example:

  • A Rare Candy cheat changes your inventory.
  • A money cheat changes your available funds.
  • A wild Pokémon modifier changes encounter data.
  • A shiny cheat changes encounter results.
  • A walkthrough-walls cheat changes movement behavior.

This is why Pokémon Heartgold action replay codes, Pokémon Heartgold action replay cheats, and Heartgold cheat codes are often used interchangeably in search results.

Common Action Replay Code Strings Explained

You may see strings such as:

  • 94000130
  • B2111880 00000000
  • D2000000 00000000
  • C0000000
  • D6000000
  • D4000000 00000001

These lines are parts of Action Replay code structures used by different cheats.

Other code strings associated with the supplied HeartGold code set include:

94000130 FCFF0000

94000130 FDFF0000

94000130 FFBB0000

1205DAA2 00001C20

The exact meaning depends on the complete code surrounding the instruction. A fragment should therefore stay with its full code rather than being treated as a standalone cheat.

The supplied research brief specifically identifies recurring strings such as d2000000 00000000, b2111880 00000000, 94000130, c0000000, d6000000, and 1205daa2 00001c20 as article terms.

Pokémon HeartGold and SoulSilver Cheats

Pokémon HeartGold and SoulSilver Cheats

Because Pokémon HeartGold and SoulSilver share much of their underlying game structure, many searches group them together.

However, you should still choose the correct code for the game you are running.

That matters for searches such as:

  • pokemon hgss cheats
  • soulsilver cheats
  • pokemon soulsilver
  • pokemon soulsilver cheats
  • soul silver
  • soul silver cheats

HeartGold follows the Pokémon Gold and Silver foundation, while SoulSilver is its paired version.

Nintendo describes both games as enhanced versions of the original Pokémon Gold Version and Pokémon Silver Version.

Pokémon Heart Gold Cheats and the Original Games

Pokémon HeartGold connects directly to the legacy of Pokémon Gold and Silver.

The remake keeps the Johto adventure while bringing the original setting to Nintendo DS hardware with updated presentation.

That makes HeartGold a useful bridge between earlier games such as Pokémon Red, Blue, and Yellow and later generations of the Pokémon video game series.

The wider Pokémon brand also includes the Pokémon (TV series), trading card game, fan projects, and many other forms of media.

For cheat-code readers, however, the important distinction is simple: HeartGold cheats are designed around the Nintendo DS game data and its Action Replay code structure.

Pokémon, Shiny Pokémon, and Legendary Pokémon

Cheats can change the way you collect Pokémon.

A wild encounter modifier can help you locate a chosen species. A Shiny modifier can change encounter appearance. Item cheats can provide Poké Balls or a Master Ball, while an EXP cheat can speed up training.

Players sometimes use these tools to find Pokémon that are otherwise time-consuming to obtain, including legendary Pokémon.

Examples commonly discussed in HeartGold cheat lists include Arceus, Celebi, Ho-Oh, Lugia, and other special encounters.

For example, the current wild modifier reference assigns Celebi the identifier 0FB, while Lugia and Ho-Oh appear as 0F9 and 0FA.

The Gen IV Pokédex contains 493 species, which explains why 493 can appear in discussions about completing the Pokédex or generating Pokémon data.

What About Arceus and Event Pokémon?

What About Arceus and Event Pokémon?

Arceus is one of the names that often appears in HeartGold cheat discussions.

Community cheat lists have included event-related Pokémon options, including Arceus and Celebi. However, event and encounter codes deserve extra care because they can alter Pokémon data beyond a simple item change.

If your goal is a clean collection, a legitimate event distribution or normal game method provides a more consistent result when available.

A cheat can still be useful for private testing or experimentation, especially when the goal is to explore the game’s data rather than maintain a completely standard save.

Pokémon HeartGold Cheats and the Pokédex

A Pokédex shortcut can be tempting when your goal is to explore the full collection.

The same applies to cheats that generate specific wild Pokémon.

Still, completing the Pokédex through normal gameplay provides a different experience because it encourages exploration across Johto and Kanto, trading, evolution, and post-game content.

Cheats work best when you decide what kind of playthrough you want first.

A short replay may benefit from Rare Candies and money. A collection-focused run may benefit from encounter tools. A testing run may benefit from movement and battle modifiers.

Battle Items, Ultra Balls, and Master Balls

  • Inventory cheats can provide battle items, Ultra Balls, and a Master Ball quickly.

    The supplied article terms specifically call for these concepts, including ultra balls, master ball, and battle items.

    A simple capture-focused setup might use:

    • Ultra Balls for regular encounters
    • Master Balls for a chosen legendary Pokémon
    • Rare Candies for team leveling
    • Max Money for shopping
    • Healing items for longer routes

    This creates a practical cheat setup while leaving most of the normal game intact.

Pokémon HeartGold Cheats and Gym Progress

Pokémon HeartGold Cheats and Gym Progress

Some trainers use cheats before a gym leader battle to prepare a team.

Rare Candies can speed up leveling. EXP cheats can reduce training time. TMs can provide more move options. Healing items can support longer sessions.

A more aggressive setup can also use battle modifiers, although those change the normal rhythm of the game more heavily.

For players who want the story experience, utility cheats are usually the easiest starting point.

For players who enjoy experimentation, encounter and battle cheats provide a much larger sandbox.

Elite Four and Post-Game Content

The Elite Four provides another common reason players use HeartGold cheats.

A replay may already be familiar, so faster EXP, money, healing items, or battle preparation can make the final stretch quicker.

After the Johto story, HeartGold opens additional Kanto content. This gives players another reason to use movement, encounter, and item shortcuts during a second playthrough.

Cheats can also be useful for exploring the post-game while preserving more time for team building and collection.

Cheats, Glitches, and Pokémon Fan Games

It helps to separate a standard HeartGold Action Replay cheat from a glitch or a rom hack.

A cheat normally applies a code while the game is running.

A glitch is behavior produced by the game’s own programming.

A ROM hack changes the game itself.

A Pokémon fan game can use completely different systems and therefore may have its own cheat mechanics.

The same distinction applies to discussions about Cheating in video games more broadly. A cheat code does not automatically mean the game has been modified permanently.

Why a Pokémon HeartGold Cheat May Behave Differently

Why a Pokémon HeartGold Cheat May Behave Differently

One of the strongest recurring questions in the supplied research is why a cheat may appear to work for one player and behave differently for another. Common factors include region, emulator, button mapping, code version, and whether multiple cheats are active at the same time.

Check these first

  1. Check the game version.
     US and EU codes can differ.
  2. Check the game itself.
     HeartGold and SoulSilver require their appropriate codes.
  3. Check the emulator controls.
     L, R, Select, and other buttons may map differently.
  4. Use one cheat first.
     This makes it easier to identify which code is producing a result.
  5. Confirm the full code.
     A missing line can change the behavior.
  6. Restart the emulator when needed.
     Some cheat effects can remain active after a code is disabled.

Current code documentation specifically recommends saving, exiting, and reopening the game when an emulator continues applying a previously enabled cheat.

How to Turn Off Pokémon HeartGold Cheats

How to Turn Off Pokémon HeartGold Cheats

Turning a cheat off usually means disabling it in the Action Replay device or emulator cheat menu.

For button-based codes, stop using the activation combination after disabling the code.

A useful cleanup process is:

  1. Save your normal game progress.
  2. Disable the cheat.
  3. Exit the game.
  4. Close the emulator if necessary.
  5. Reopen the game.
  6. Load the clean save.
  7. Confirm normal gameplay.

Some current code documentation notes that certain cheats may remain active after being disabled until the game is saved, closed, and reopened.

Can Cheats Affect a Save File?

Yes, cheats can change the data stored by a Pokémon HeartGold save.

That does not mean every cheat automatically damages a save. It means the safest approach is to maintain a backup before using memory-changing codes.

The greatest care makes sense with:

  • Wild Pokémon modifiers
  • Shiny modifiers
  • Pokémon data changes
  • Movement cheats
  • Badge cheats
  • TMs/HMs modifications
  • Multiple active cheats
  • Experimental codes

A simple item or money cheat generally has a narrower purpose than a code that changes Pokémon generation or game progression.

Safe Way to Use Pokémon HeartGold Cheats

Safe Way to Use Pokémon HeartGold Cheats

A clean cheat routine looks like this:

Step 1: Back up the save

Keep an untouched copy before testing a new code.

Step 2: Identify the version

Confirm the HeartGold region and game release.

Step 3: Pick one cheat

Start with a simple item or money code.

Step 4: Read the activation method

Some codes use L + R, while others use Select, Up, or another button.

Step 5: Test the result

Check your Bag, party, money, or encounter.

Step 6: Disable the code

Return the game to its normal state when the desired result is complete.

Step 7: Restart when needed

A fresh game session can clear lingering cheat effects.

Step 8: Keep the backup

Your original save remains your best recovery point.

A Note About Nintendo DS and ROM Terminology

The original game runs on the Nintendo DS.

A ROM is a digital copy of game data, while an emulator is software that reproduces the relevant hardware environment.

That is why searches often combine terms such as Nintendo DS, ROM, emulator, and Action Replay.

The official Nintendo information identifies Pokémon HeartGold as a Nintendo DS release, while Pokémon’s official page describes HeartGold and SoulSilver as Nintendo DS and Nintendo DSi games.

Pokémon HeartGold Cheats on Nintendo DS Hardware

Pokémon HeartGold Cheats on Nintendo DS Hardware

On original Nintendo DS hardware, Action Replay codes generally require compatible Action Replay hardware.

The basic process is:

  1. Connect the Action Replay device.
  2. Start the Nintendo DS.
  3. Select Pokémon HeartGold.
  4. Choose or enter the required Action Replay code.
  5. Start the game.
  6. Follow the listed activation button.

The physical-button method differs from emulator keyboard mappings, so a code that says press L + R to activate refers to the Nintendo DS controls.

YouTube, Community Guides, and Code Lists

YouTube can help readers see how a cheat behaves on screen, especially when a code requires a particular button combination.

Community code lists can also reveal practical details such as region differences and emulator mappings.

However, community reports should be treated as supporting evidence rather than a guarantee that every code works with every HeartGold version.

That distinction matters because readers often share their results through comments, forums, YouTube, and other Pokémon communities.

What About Pokémon TV and the Wider Pokémon Franchise?

Pokémon HeartGold is part of the larger Pokémon franchise rather than a game created specifically for the Pokémon (TV series).

The game belongs to the Pokémon (video game series) and directly revisits the world introduced by Pokémon Gold and Silver.

That broader connection is one reason HeartGold remains popular with longtime fans who remember Pokémon Red, Blue, and Yellow and later returned to Johto.

The game’s official Nintendo material describes the Johto adventure and its story around Professor Elm, Team Rocket, and the player’s journey toward becoming Champion.

What Readers Should Know About Current 2026 Cheat Lists

HeartGold is an older Nintendo DS game, so the game itself is not receiving a modern gameplay patch cycle comparable to newer Pokémon titles.

The main 2026 concern is therefore code compatibility, especially across different ROM regions and emulator setups.

A current HeartGold code reference updated July 27, 2026 reports verified codes tested on DeSmuME and Delta for iOS and separates US and EU versions.

That makes version matching more useful than simply choosing the newest-looking code list.

Frequently Asked Questions

The most useful options include Rare Candies, max money, Poké Balls, battle items, TMs/HMs, EXP, Shiny Pokémon, wild encounters, and walk through walls. The best choice depends on whether you want faster training, easier collecting, or simple quality-of-life improvements. Current code references list these categories among their verified HeartGold options.

Yes, current community-maintained lists still document HeartGold Action Replay codes in 2026. One updated July 27, 2026 reference reports testing selected codes on DeSmuME and Delta for iOS.

Open the emulator’s cheat manager, create an Action Replay entry, paste the complete code, enable it, and use the required activation buttons. Check the ROM region first because US and EU codes can differ.

A commonly listed x999 Rare Candies code is activated with L + R:

94000130 FCFF0000

B2111880 00000000

00000B74 03E70032

D20000000000000

The current verified reference identifies this as the x999 Rare Candies in Bag option.

Yes. A current HeartGold code list includes a Max Money Action Replay code activated with L + R, plus an alternative version for different behavior.

Yes. A current verified list includes a Walk Through Walls code activated by holding L. Older North American references also document an R+B activation version.

Yes. HeartGold Action Replay lists include wild Shiny Pokémon modifiers. Some references attach specific warnings around breeding, so using the modifier for a simple encounter and then disabling it is a sensible approach.

A wild Pokémon modifier can change the species that appears during encounters. Current code references use species identifiers, allowing players to select from a large Pokémon list.

Start by checking the ROM region, game version, complete code, emulator, and button mapping. Current documentation specifically identifies different emulator button assignments as a common reason for activation problems.

They can change game data, so keeping a backup is a smart precaution. Item and money codes have narrower purposes, while Pokémon modifiers, movement codes, and other memory-changing cheats deserve extra care.

Some cheat structures are similar because the games share the same generation and Nintendo DS foundation, but HeartGold and SoulSilver codes should still be treated as version-specific. Use a code explicitly identified for your game whenever possible.

Not every modern Action Replay code list uses a separate master code. Many individual codes are presented as complete entries that you add directly to an emulator or Action Replay manager. Follow the instructions supplied with the specific code rather than adding an unrelated master code.
