I've been trying to download the system files for the 3DS from Nintendo servers; It doesn't work

I’ve got the 3DS slot key bin files necessary to download the system files from the Nintendo servers, but it doesn’t work for me. Every time I try to, Citra just closes itself.

System Information

  • Operating System: Dell Latitude 3190 with Intel Pentium Silver
  • CPU: Doesn’t matter
  • GPU: Doesn’t matter
  • Citra Canary 2419
    Can’t screenshot the issue, because it keeps closing out of Citra whenever I have it.

The diagnostic log isn’t relevant to the problem I’m having.

In order for us to provide better support, we need to see the log generated by citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File

for me it doesn’t really detect the aes_keys.txt file

Do you have the seeddb.bin file that is also required?

were do i need to put it?

Put it inside of the sysdata folder inside of the folder that opens when you click the Open Citra Folder option in the Citra app.

done but still nothing…

Actually, double check that you’re on the latest Canary build and are still having this issue.

I’m also on the latest version of Citra Canary and though I finally got it to download the files, but now it tells me that the format is not supported, and I have no clue what to do now.

When does it tell you this? Please also upload a screenshot of the error.

It tells me this whenever I click the Boot Home Menu option on the file menu for Citra, and oddly enough, while it didn’t say Citra was missing keys just a little bit ago, it says in the configuration menu that Citra is missing the keys necessary to download system files now.

Please set up a new portable build:

Go to Download Citra - Citra and select Manual download. Then under Nightly Build, click on your operating system’s icon to the right of the latest build available to download the build.
Extract it (.7z can be extracted using Winrar or 7zip) and put it wherever you wish. Inside the extracted nightly-mingw folder, create a folder called user. This Citra should now store all of its config, save files and such inside of this user folder.
Check to make sure that this user folder is in the same folder that contains citra-qt(.exe)
Now run the citra-qt executable found inside of the mingw folder.

Dump your files using ThreeSD again (if you deleted them from your SD-Card previously). Copy the threesd(.exe) file to your portable Citra build (in the same folder as citra-qt(.exe)). Run threesd(.exe). When you get to selecting what to import, make sure to that you’re dumping all of System Archives, System Data and System Applets (it will give you a warning when selecting this one. Ignore it). You can now dump it.

Open your portable Citra build and go to Emulation>Configure>General and set the Region here to USA (since your 3DS appears to be North American judging by your screenshot). If the region is not set to the region of the home menu, it will not launch. After setting the region, go to File>Boot Home Menu. Lemme know how that goes.

Does downloading the system files from the Nintendo servers use a browser? If it does, do you know if it uses the default browser or not? Because I downloaded them from a different computer, since Citra closes down any time that I try on the computer I’ve got all of my data on currently, and then transferred it to the computer with all of my data. I don’t remember whether I set the region on that other computer or not. By the way, I was not about to transfer all of my data over to the computer that does work when downloading the files, because that computer was a Butler Tech desktop.

It does not use a browser at all for this.

I have no idea what you’re trying to say here.
“downloaded them from a different computer”? If you already had downloaded the data, it’s a simple transfer. “then transferred it to the computer with all my data”? What data? If it’s the system files, then why do you need to transfer system files to a computer that already has those system files?

All of what “data”? I also have no idea what a “Butler Tech desktop” is supposed to mean…

The save states and everything else of mine from the emulator. I had it all saved to a computer that apparently wasn’t able to download the system files. So, I ended up having to get onto another computer in order to download the system files, uploading the files to my OneDrive, and then downloading them onto the computer with all of my save states, and games on it.
