Pokemon White 2 Cheat Codes: What Most People Get Wrong

You’re standing in front of the PWT, or maybe you’re just tired of grinding Audinos in the shaking grass for the tenth hour this week. We’ve all been there. Pokemon White 2 is arguably the peak of the 2D era, but man, it can be a slog. Whether you’re playing on a dusty Nintendo DS or firing up an emulator like DeSmuMe, you’re probably looking for a shortcut.

But here’s the thing. Most lists of Pokemon White 2 cheat codes you find online are a mess. Half of them are for the original White version (which won't work), and the other half are just broken hex strings that might turn your save file into a "Bad Egg" graveyard.

I’ve spent years tinkering with Action Replay (AR) codes. I’ve crashed my game more times than I can count. Honestly, if you don’t want to lose your Level 100 Serperior, you need to be careful. Let’s break down what actually works in 2026.

The Absolute Essentials: Master Balls and Rare Candies

Most players just want the basics. You want to catch that roaming Latias without chasing it across half of Unova, or you want to level up a newly hatched Larvesta without spending three days in Victory Road.

For these to work, you usually need to press a "trigger" button. Most of these are set to Select or L+R. If you put the code in and nothing happens, check your bag. Often, the items won't just appear; they replace whatever is in your first slot or specific medicine slot.

Rare Candy Code (999 in Medicine Pocket)
This one is a lifesaver. Press L+R to activate it.

D2000000 00000000

The "Catch Anything" Master Ball Code
Standard Master Ball codes can be finicky. This one gives you 999 Master Balls in your Items pocket. Again, hit Select once you’re in the game.

D2000000 00000000

Be careful with the item codes. If your bag is already full, the game might get confused. I always suggest tossing a few useless items like Berries or Potions before you trigger the cheat. It gives the code "room" to breathe in the game's RAM.

Breaking the Rules: Walking Through Walls

This is the holy grail of Pokemon White 2 cheat codes. Want to skip the annoying puzzles in Clay’s Gym? Or maybe you want to see what’s behind those trees in Floccesy Town?

The "Walk Through Walls" (WTW) code is legendary. It works by disabling the collision detection in the game's engine.

Walk Through Walls (Hold L to Move)
521639A8 2010D101
121639AE 00001C20
94000130 FDFF0000
121639AE 00000200
D2000000 00000000

A word of warning though: Do not save your game while you are standing inside a wall or on top of water where you shouldn't be. If you turn off the cheat and reload, you might be "soft-locked." Your character will be stuck in the black void, and unless you have another cheat to warp out, that save file is toast. Use it to get where you're going, move to a "legal" tile, then save.

Why Your Codes Aren't Working

It's frustrating. You paste the code into your emulator, hit "Enable," and... nothing. Here are the three most common reasons why:

1. Region Mismatch: This is the big one. Codes for the Japanese (J) version of White 2 will not work on the US (U) or European (E) versions. The memory addresses are shifted. The codes in this article are specifically for the US Version (Game ID: IRDJ-0146c7a8).
2. The "Master Code" Myth: Back in the day, physical Action Replay carts needed a "Master Code" (usually starting with (M)) to even boot the game. On modern emulators like DeSmuMe or MelonDS, you don't need these. They actually cause more crashes than they fix.
3. Conflict: Trying to run "Max Money," "999 Rare Candies," and "Shiny Encounter" all at once? You're asking for a crash. The DS has very limited memory. Overwriting too many addresses at once causes the game to hang on a black screen.

Leveling and Money: Skipping the Grind

Let's talk about the economy. In White 2, money isn't huge until the post-game when you're buying vitamins or expensive Join Avenue upgrades.

Experience Multipliers
If you don't want to just "cheat" Rare Candies and want to actually battle, use an EXP multiplier. It feels a bit more natural.

• 2x EXP: 521B970C 1C210C00 (plus the rest of the string)
• 10x EXP: 121B970E 0000210A

Honestly, 10x is plenty. Anything higher and you'll hit Level 100 after two battles with a Patrat, which kind of ruins the fun of the Gym Leader fights.

The "Wild Pokemon Modifier" Trick

This is the most complex of the Pokemon White 2 cheat codes, but it’s the most powerful. It allows you to encounter any Pokemon in the game—including Legendaries like Genesect or Keldeo—just by walking into tall grass.

The most common version of this code works by giving you a specific number of Master Balls.

1. You trigger the code (usually with Select).
2. The game gives you 649 Master Balls (representing the National Pokedex count).
3. You discard Master Balls until the number remaining matches the Pokedex ID of the Pokemon you want. (e.g., if you want Bulbasaur, discard until you have 1 left).
4. Hold R while walking into grass.

It’s tedious. It’s manual. But it’s the only way to get event-exclusive Pokemon in 2026 without using a save editor like PKHeX.

Avoiding the "Bad Egg"

You might have heard horror stories about Bad Eggs. A Bad Egg is essentially a corrupted data structure that the game doesn't know how to read. It happens most often with "Shiny" cheats or "Capture Trainer's Pokemon" cheats.

If you use a code to force a Shiny encounter, the game has to recalculate the Pokemon's PID (Personality ID). If the code is sloppy, the PID and the IVs won't match the checksum.

The Golden Rule: Always keep a backup of your .sav file. If you’re on a PC, just copy the file to a different folder before you start experimenting. If you’re on hardware, well, you’re playing with fire.

Actionable Steps for Success

Ready to start? Don't just dump all these in at once.

• Step 1: Verify your game version. Check the "Game ID" in your emulator settings. It should be IRDJ-0146c7a8 for the US version.
• Step 2: Add codes one by one. Don't enable them all. Enable one, trigger it (press Select/L+R), confirm it worked, and then save your game normally.
• Step 3: Disable the code. Once you have your 999 Rare Candies, you don't need the code running anymore. Turn it off to keep the game stable.
• Step 4: Use the "Hold" codes sparingly. Movement speed and Walk Through Walls codes are the most likely to cause the game to freeze during a transition (like walking into a house). Let go of the trigger button before you cross a door threshold.

The beauty of Pokemon White 2 is the massive amount of content. Cheats should help you enjoy that content, not skip it entirely. Use them to bypass the boring stuff so you can get back to what actually matters: being the Champ.

Next Steps for Your Game:
Start by backing up your current save file to avoid any loss of progress. Once protected, input the Max Money code first—it's the most stable and a great way to verify your Action Replay setup is working correctly before moving on to more complex movement or encounter modifiers.
