This is a very simple batch file to decrypt CIA & 3DS files for beginner, the CIA will be decrypted and converted to CCI or only be decrypted CIA which able to install in Citra.

Please use legal way to get game files before use this pack.



Usage:

Run "Batch CIA 3DS Decryptor.bat".
Then waiting it finished. (It will take a lot of memory/ram when these files are too big.)

Could we get source code for decrypt.exe? Not everyone runs windows.
Look your PM, but you also need makerom.exe for your OS, other way, you would only get a incomplete file, but you can still play it on Citra.

It has a source code version, written in python. You can get it by searching decrypt_v2.zip on Google.
Sorry, I missunderstanding before, edited, thanks for reply.

You accidentally put your GitHub and not the project GitHub dude
Thanks for notice.

This version of C:\Users\PC\Desktop\Batch CIA 3DS Decryptor\decrypt.exe is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.

I have 32-bit so assuming this is only for 64-bit then?
in that case is there a different program or version of this that will work on 32 bit windows?

I can't find a 32bit version, and if you want to play Citra, you also need a 64bit system.

Updated, add a file for DLC install in CItra.

Updated

Merge "Decrypt DLC-CIA for Citra.bat" to "Batch CIA 3DS Decryptor.bat".
Will not delete files which named decrypted that older version did.
Add support for patch files..

I followed the instructions to a the T, but no matter what I do, it keeps saying the rom is encrypted with Citra. I cannot get around it

Looked in the log, says "content 0 is corrupt", does anyone know what that means?

my laptop suddenly freezed in the process of decryption. is it ok to decrypt the files again after what occurred? because at first i thought it was just due to lag but then i noticed my music stopped playing and i couldn't move the cursor at all.
