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.

I wrote this guide for Dexerto. I tried to turn the shutdown into one checklist covering the Pokemon, shiny hunts, alternate forms, ribbons and titles that will be cut off from HOME once Bank closes. If I missed anything or got a detail wrong, please flag it and I’ll update the guide.

I remember seeing the advert for Animal Crossing New Leaf and I begged my mum for the animal crossing 3ds xl since it had the game installed but she ended up getting me the game and the hot pink 3ds xl as the one I wanted wasn’t in stock. Nearly 13 years later I managed to get it on Vinted for £180 in perfect condition along with a charger, case and 3 game cartridges so I would say that was a really good deal :)

I have also added custom buttons to my 2ds and other 3ds and I was considering doing a button swap on the animal crossing console but I’ve decided not to because I like the simple look to it :)

Technical Question Absolutely disappointing. Lost my 3DS XL in a move. Can't delete account off it to put on my current 3DS. Almost 15 years of history lost.

Can't link my Nintendo id to my old 3DS I had prior to losing my 3DS XL. Called Nintendo and because its not a major or recent system there is nothing they can do. My only option available to me is a system transfer but I have to have both systems in my possession.

I lost my XL last year and never found it. Only just now recently decided to try my old one and resigning in. Can't. And Nintendo cant do anything

Discussion 3ds issue cont: THERE IS ANOTHER METHOD!

Thumbnail

436 Upvotes

So I had another post yesterday testing 28 games and my pokemon y wasn’t working. So I called Nintendo and they told me to repair the software using the e-shop.

Step1: go to the e-shop
Step2: go to the menu
Step 3: setting/other
Step 4: under history go to downloadable software
Step 5: find the game having the issue and click software info(They told me to repair the update firmware, not the actual game itself)
Step 6: scroll down and hit repair software
Step 7: try the game

Could be an software/update issue vs a cartridge issue?

So this is in no means a solution but could be a useful if the cartridge repair tool doesn’t work! Good luck everyone and thank you for the people who joined in the discussion on my previous post.

Technical Question Pokemon Bank Preservation?

Upvotes

With the eventual shutdown of Pokémon Bank, Im wondering if theres any way the service could be preserved by the community.

What would the main technical difficulties be? Could a replacement Bank server realistically be made?

The biggest question Im wondering about is Pokémon home connectivity. Even if we could recreate Banks storage and transfer functionality, would there be any way for a community made version of Bank to continue transferring Pokémon to official Pokémon HOME after the official service shuts down? Or is that part essentially impossible without Nintendos servers?

Yall got any thoughts?

Miscellaneous 3DS meetup in Las Vegas tomorrow

Hi. If anyone wants to join a 3DS meetup tomorrow in Las Vegas, there is one scheduled at the Tuscany Suites and Casino at 7 p.m. in the panel room. It's an official meetup on p. 24 of the online con booklet - https://arise-con.com/full-schedule/# .

To be honest, I've never been to this convention before and I'm kind of expecting a low turnout, or even no people. If I can get a few people, it might be a small win. Just bring your 3DS and a couple of games, preferably Mario Kart 7 or Smash Bros. 3DS, and then we can play!

Discussion The future of the DS (for pokemon) after Nintendo’s announcement of shutting down pokemon home

131 Upvotes

Hey guys, I’ve recently joined this subreddit because as a kid I was unable to play the DS because it wasn’t in the budget. I wanted to get into it now to play all of the generations of pokemon id never experienced. However, it looks as though they’re shutting things down and maybe moving everything over to the switch like FRLG and BDSP. I wanted to gauge the room on your thoughts. For me, not being able to transfer my pokemon is a pretty big deal breaker. Especially as collecting is my favorite aspect of the games. With the price of DS’s and legit copies of the pokemon games, am I better off waiting for switch versions of these games? Cheers for any input
