    Could we get source code for decrypt.exe? Not everyone runs windows.

    It has a source code version, written in python. You can get it by searching decrypt_v2.zip on Google.

    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.

    i get this error in the log when trying to run this

    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.

    @matif you could always just distribute the python source file and run it through the system python -- that way there'll be no issue with 32bit vs 64bit.

    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..

    Any idea what this error means? @matif
    [SETTING ERROR] Argument "-rsf" is required
    My last step before I'm done, please help!

    I can't see the point of this as citra can now read encrypted files

    pretty sure decrypted files are still needed for doing any mods to a game. This is not only a citra made thing. The citra part is done but there is futher use.

    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.
