Honestly, playing Pokemon Platinum in 2026 feels like a time capsule. You’ve got the clunky Poketch on the bottom screen, the slow-motion health bars, and that specific anxiety of walking into the Distortion World without enough Revives. Most of us who still have our original DS Lite or DSi tucked in a drawer eventually get the itch to skip the grind. That’s where ds action replay pokemon platinum codes come in.
They were basically the Wild West of the Sinnoh region. One minute you're trying to get a few extra Rare Candies, and the next, your bag is full of 999 Master Balls and your character is walking through walls into the "Mystery Zone" void. It’s a lot of power for a handheld. But if you don’t know what you’re doing, you can genuinely mess up a save file you’ve had since 2009.

Let's get into what actually works and why some of those old codes might be crashing your game today.
Why Some Codes Freeze Your DS
If you’ve ever entered a 12-line string of hex and had your screen go white the second you hit L+R, you aren't alone. Most people think their Action Replay is broken. Usually, it's just code conflict.
The most common culprit is the "Wild Pokemon Modifier." This thing is a beast. It uses the Poketch Calculator to intercept the game's RAM. If you try to run a "Shiny Code" at the exact same time as a "Level Modifier," the game engine basically has a panic attack. It’s trying to force a level 100 Adamant Arceus into a patch of grass in Route 201, and the hardware just can't keep up.
A lot of the codes you find on old forums like GameFAQs are specifically for the US Version (CPU-EN). If you’re playing on a European or Japanese cartridge, those codes will almost certainly crash the system. Check the small ID on the front of your cart. If it doesn't match the code's region, don't even bother typing it in.
The Essential "Must-Have" Codes
You don't need 50 cheats. You usually just need the three that save you ten hours of mindless grinding.
The Rare Candy Hack (Medicine Bag)
Most people look for a standalone Rare Candy code, but those are notoriously buggy. The "pro" way to do it is the 900x All Medicine code. It fills your medicine pocket with everything—Max Potions, Full Restores, and yes, the Rare Candies.
- The Code:
- 94000130 FCBF0000
- 62101D40 00000000
- B2101D40 00000000
- D5000000 03840011
- C0000000 00000025
- D6000000 00000B60
- D4000000 00000001
- D2000000 00000000
How to use it: You enter the code, start the game, and press L+R at the same time. Check your bag. If it's not there, you might need to go into a PokeMart first. A quick heads-up: using Rare Candies means your Pokemon won't gain Effort Values (EVs). They'll be level 100, sure, but they’ll be significantly weaker than a Pokemon you actually trained.
Walking Through Walls
This is the legendary "ghost mode." It’s how people used to find Darkrai and Shaymin before the official events were released.
- Activate: Press R+B
- Deactivate: Press L+B
It basically disables the collision detection in the game. You can walk across the ocean or straight through the trees behind the Pokemon League. Just be careful. If you save your game while standing inside a wall and then turn the cheat off, you are stuck there forever. Your save is dead.
Catching the "Uncatchable" Events
Since Nintendo shut down the DS Wi-Fi servers years ago, you can't get the Azure Flute or Oak's Letter normally anymore. This is where ds action replay pokemon platinum codes are actually a godsend for completionists.
Instead of just "spawning" a Shaymin, it's way safer to use a code that triggers the Mystery Gift event. This puts the event item in your bag, so the game thinks you actually went to a Toys "R" Us in 2009. You go to the Flower Paradise or the Hall of Origin, and the encounter happens "naturally." This prevents the "Bad Egg" glitch that happens when you force-spawn a Pokemon into your party.
The Catch Rate Secret
Let’s talk about the 100% Catch Rate code. It’s sort of the "lazy man’s Master Ball." You can throw a standard Poke Ball at a full-health Giratina, and it’ll click on the first shake.

9224A948 00002801
1224A948 00004280
D2000000 00000000
It’s always on. No buttons required. It’s remarkably stable, though it feels a bit like stealing the soul out of the game.
Common Misconceptions and Risks
"Will Action Replay fry my DS?"
No. The console itself is fine. The cartridge's "ROM" (the game data) is read-only, so you aren't changing the game permanently. What you are changing is the "SAV" file.
The real danger is the Bad Egg. This is a corrupted data slot that looks like an egg but never hatches. If it ends up in your party, it can start overwriting other Pokemon data. If you see one, do not save. Turn the power off immediately.
Another weird one is the "National Dex" glitch. If you use a code to unlock the National Pokédex before you’ve actually seen all the Sinnoh Pokémon, it can sometimes prevent the endgame NPCs from appearing. You end up stuck in a world where you're the champion but the Battle Frontier won't open.
Moving Forward With Your Save
If you’re going to use these codes, the best move is to be surgical. Use the code, get the item or the Pokemon you want, save the game, and then turn the cheat off. Running with 10 cheats active at once is a recipe for a frozen screen.

For those of you using emulators or flashcarts like the R4, the process is way easier since the cheats are usually pre-built into the menu. But on real hardware? Treat it like a science experiment.
- Back up your save if you have a way to do so (like a Joey Jr. or an R4 backup tool).
- Never save in a place you couldn't reach without "Walk Through Walls."
- Limit yourself to one or two active codes at a time to prevent RAM overflows.
- Check your ID to ensure the codes are for the US version of Platinum.
The Sinnoh region is huge, and sometimes you just want to see what's behind that locked door in Canalave City. Just remember that once you start cheating, the "magic" of the challenge disappears pretty fast. Use these to skip the boring stuff, not to skip the game itself.
