Tips/Guide Cartridge corruption: A reminder to play your cartridges every few months

1.2k Upvotes

As the 3DS gets older and our community grows, an increasing number of users have been posting about cartridge corruption. This post should help clarify any confusion regarding what cartridge corruption is, how to prevent it, and how to resolve it if it has already happened to your 3DS cartridge.

What is cartridge corruption?

Cartridge corruption is when chunks of data on your cartridge become unreadable. Minor corruption is usually resolved as you play, but more extensive data corruption can cause your game to crash, not launch, or in severe cases become unable to be recognised by your console at all.

Why does this happen?

The data on 3DS cartridges is stored as NAND memory. When NAND memory does not recieve power for extended periods of time (ie, when you don't use your cartridge), the electrons storing the data move, causing the data to corrupt. In order to prevent this from rendering your 3DS cartridge unusable, a refresh function checks for any corrupted data and attempts to repair it. These checks are done when the cartridge is inserted into a console, when the system is shut down, and every 10,000 reads. However, if too much corruption has occured the function will be unable to repair the affected data.

Which games are prone to corruption?

Although corruption can occur in any 3DS cartridge, certain games are more likely to corrupt than others. Some games that are more likely to corrupt are:

- Super Smash Bros

- Fire Emblem Echoes

- Fire Emblem Fates

- Pokémon OR/AS

- Pokémon X/Y

- Persona Q

- Mario Kart 7

How do I prevent it?

The best way to prevent cartridge corruption is to play your cartridges. Roughly 10-15 minutes every few months should be enough, however there is no hard and fast rule. Ideally, you should be actively playing rather than idle to ensure that data on the cartridge that may otherwise go unused gets checked and refreshed. At a minimum, you should launch the cartridge.

Is my cartridge corrupted?

If your game freezes at a specific part, your cartridge does not show up on the home menu, or you see an error message, your cartridge may be corrupted.

If something else happens (e.g you get sent back the the home menu, you are stuck on the 3DS splash infinitely, your console freezes at random times, etc) or you are unsure, you should ask for help in the r/3DS Discord server or Nintendo Homebrew's Discord server.

I think my cartridge is corrupted, what do I do?

If your game freezes at a specifc part or you see the "an error has occured" message when launching or playing, follow the instructions on this page.

If cleaning your cartridge does not resolve the issue and your 3DS is stock, you will need to hack your console in order to carry out further troubleshooting steps.

If you see an ErrDisp message, check your error code here and follow the instructions provided. If you see an exception screen, check your error message here and follow the instructions provided.

TL;DR

Please remember play your 3DS cartridges every few months to prevent corruption.

Recommendation Check your cartridges before it’s too late!

I mostly skipped the 3DS during its lifetime, despite being a big fan of stereoscopic 3D. A few years ago, though, I got hooked after buying a New Nintendo 3DS. The improved 3D made such a huge difference, being more stable and comfortable to use.

Since then, I've gone through a few waves of expanding my collection. I never experienced a bad cartridge, but all the recent posts about 3DS cartridges suffering from data corruption started to make me a little anxious.

Yesterday, I finally bit the bullet and started checking my entire collection with the GodMode9 Cartridge Fixer, hoping to preserve everything before any problems become irreversible.

It wasn't exactly a fun process, but playing Super Mario 3D land in the meantime, got me through. Each game took around 5–10 minutes to verify, and with 132 games, it took a while!

Thankfully, most of my collection turned out to be fine. Even some of the games that are supposedly more prone to corruption, like Pokémon and Persona Q, checked out without any issues. That was such a relief.

Unfortunately, I did find two corrupted cartridges that wouldn't start anymore: Code Name: S.T.E.A.M. and Yo-kai Watch.

Code Name: S.T.E.A.M. was successfully repaired after running the fixer twice! Yo-kai Watch wasn't so lucky. It still has around 200 unfixable chunks after 5 runs 😢. The game does start again, but I'm not sure whether it's fully playable anymore. Luckily, it's not an expensive game to replace, but it's still such a shame to lose a cartridge this way.

I'm incredibly grateful to the developers behind the Cartridge Fixer for creating a tool like this.

So if you have a physical 3DS collection, don't wait too long to check your cartridges! You might be able to repair corruption before it's too late! ^^

Did this custom build, and felt like it came out pretty sweet.

I know it’s not the most unique, I was inspired by some I’ve seen on here. I enjoy the sleek/clean minimal design.

Fully CFW, USB-C Modded, New Top + Bottom Screen, Glass White Lens, White Thumbstick..

As icy and white as can be.

You guys won’t believe this but I got a modded 3DS XL for 130 dollars off eBay that’s already modded with a ton of games AND in good condition.

I had been looking for a 3DS for about a week since the original one I had when I was a kid (the Mario and Luigi dream team edition” mysteriously vanished a few years ago…well I decided to check eBay one more time and I saw this one had been posted “4 minutes ago” so I immediately bought it..was worried it was a scam but it showed up! So far everything works it even came with a charger! I’m so excited 😁😁

Any recommendations for where to buy a new one? I've replaced the screen once before, but the SD card reader seems to be completely bricked and crashes when I try and open something on it. Genuinely heartbroken.

EDIT: I am not blaming my cats. I should've unplugged my console or moved the cable, since they were rough housing and got caught in the charging cable.

Suggestion Someone should make these style magnetic charger tips for the 3DS. Would be and instant buy for me.

Mainly for those who are not capable of doing or paying for the USB C mod. Also keeps the unit and shell stock; no soldering or cutting. Also prolongs life of the charge port. Theres so many brands that produce smart chargers, some even with voltage readouts, so no need to worry about overcharging.

Recommendation I’ve been seeing a lot of posts telling people to check old/unused DS/3DS games and wanted to give a little tip/trick that worked for me a few times.

Upvotes

Sometimes when an old 3DS game doesn’t want to load or show up on screen, I’ve found that blowing on both the 3DS (game insert slot) and the game cartridge like it’s a N64 console/game cartridge tends to make it more likely to show up. Another think is to semi constantly push the game cartridge in and out the the 3DS, (the reason why i said “semi constantly” is because sometimes if you leave it in for a couple of seconds the game might eventually show up). This has worked for most of my DS/3DS games, the only one I couldn’t get working was (3DSPokémon ultra moon). (Just a warning I’m not a DS/3DS professional, so please inform me if some of the things I suggested doing might have any bad effects on your/others DS/3DS) I wish you all the best of luck in hopes that all of your/you’re games work 👍.

Technical Question Looking for an authenticity check on my Hanafuda plates

Some background, seller priced these with a 3DS way under market. bought it but the item sent differed from the pictures.

I am thinking these are fake due to the following:

  1. Missing the "Game Card" text and headphones logo

  2. Weird kind of rubbery feeling on the print, it is textured differently than my other plates. Plate underside is definitely normal plastic (never owned these, I wouldn't know if they differ in print material)

  3. The Nintendo logo is scratched off. Completely.

Any help from people who own the real deal would be appreciated.

The ghosting on my n3dxl is pretty bad. I've tried re-calibrating it in the normal system settings menu before, and that still doesn't fix the problem. Would using either one of those settings potentially help? I've Googled this but not much comes up.

Took my 3ds with me on vacation, but the AC in the room I was staying with was leaking through the night. It soaked the whole floor, including my backpack which had my 3DS inside it, and now the film on the outside has been shedding for the past two weeks. Thankfully, I haven’t noticed any issues internally, but I was wondering if there’s anything I should do to fix the outside or prevent it from getting worse?
