Homebrew Batch CIA 3DS Decryptor - A simple batch file to decrypt CIA & 3DS

[luathnat]

I cannot get this to work, the log file says:


'decrypt' is not recognized as an internal or external command,
operable program or batch file.

Any idea?

How do you run this on Android?

You don't.

Everything works as it should, I try to install the dlc, it should a loading bar and... nothing, as if I never installed anything...

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.
GitHub: https://github.com/matiffeder/stuff
Downlaod: https://gbatemp.net/download/batch-cia-3ds-decryptor.35098/download?version=35152



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



Usage:
Put XXX.cia and XXX.3ds games, DLC & Patch to the folder of the pack, support multi-files.
Run "Batch CIA 3DS Decryptor.bat".
Then waiting it finished. (It will take a lot of memory/ram when these files are too big.)
If there are some games not able to decrypt, please put your seeddb.bin in the folder of the pack.


Features & Effects:
One key batch decrypt CIA & 3DS files.
DLC/Patch CIA > Decrypted CIA, able to install in Citra.
3DS Games > Decrypted and trimmed 3DS, so it is smaller.
CIA Games > Decrypted CCI (NCSD), not CXI (NCCH).
Auto dectect CIA type (DLC/Patch/Game).

Works like a charm. Thanks.

Anyone have an updated version of this? I get

struct.error: unpack requires a string argument of length 4

when trying to decrypt an NCCH inside an encrypted .cia from the eShop.

Google says this is an issue with python reading the file padding but I have no knowledge of how to fix it.

Hi
I used this tool and it seems to work just great. But I have three question about it.
Q1: When I decrypt a 3ds/cia file, the outputted file is not always the same. Meaning that if I do the following:
1- Decrypt the file {Game.3ds} and it gives me the file {Game-decrypted.3ds}
2- Move {Game-decrypted.3ds} to another place (desktop)
3- Decrypt the file {Game.3ds} again and it gives me the second {Game-decrypted.3ds}
The hashes (MD5) for the two outputted files are not the same. Why? is the process somehow different each time I use the program?
Q2: Is there a way to disable the trimming feature. Just in case I want to use another program to trim like (NDSTokyoTrim 3.1) or don't want to trim at all?
Q3: Is there a way to reverse the process (getting the encrypted files back, with the original hash) ?If it is impossible with this tool (or after the use of this tool), then is there a way to decrypt 3ds/cia files that is reversible?
*I use the tool for decrypting my files for emulation with Citra.
*I didn't decrypt the already decrypted files again, but I decrypted the original file twice to check if it gives me different results, which it did (MD5 mismatch). Also, I did check if the original file was changed after the first decryption, and it wasn't (MD5 match).
So, this tool seems to give slightly different results when applied on the same file. The inconsistency is surprising (and maybe unreliable), which made me ask Q1.
*I want the ability to return my decrypted files to their original encrypted form (MD5 perfect) for archival purposes, which made me ask Q2, Q3

Note: I'm a noob .So, if there are Windows tools (so that I don't brick my 3DS) or ways to do this (or some step by step explanation) it would be appreciated. If there isn't, then go ahead and hit me hard with what you have.

how do I use the code? I have a Mac OS... I don't know what to do lol helppp pls

I don't know what to do with the code, I have a MAC OS, help please lol

 

[Deleted User]

Why when i open the .bat, it says "Finished, please press any key to exit" right off the bat and does not a single progress?
Update: it was my fault to run this as administrator. Oopsie oopsy?

 

[WD_Cipher]

Im having the same issue, but same happens just whenever I open it through any means
can someone please help me with this

Try yo update your seed.bin. Make sure your cia is intact.

At this moment I don't have mac version. If you need more helping, you can PM me.

Do you have a log.txt? Could you tell me what it wrote in the file? Which file you were trying to decrypt? Thanks.

Could you tell me more detailed steps that you did? Also, maybe you could answer the questions that I asked above. Thanks.

A1: I think the way that "makerom" does is like packing, it packs up ncch files. You could try to pack up any same files to zip two or more times. The md5 of those zip are always different.

A2: I would like to help you to do that thing, but I need time to find that file.

A3: The original file is always there. The tool will not delete that.

There is a file called decrypt.exe needs to be in the folder. Check if you extracted all the files.

Everything is working as intended, I install the DLC, it shows a loading bar and... nothing, as if I didn't install any DLC.

Which game and dlc you are trying?

Anyway, this way is safe. If you need, I can give you .3ds version which will not change md5 and not trim, now.

Sorry, I forgot to reply.
About your problem, it's because of that your memory/ram in the computer was not enough while you were decrypting the rom. So, you should close the game you are playing or any software which are not needed, or reduce the number of roms that you are trying to decrypt.

I´m having the same issue with some files. I've successfully decrypted Pokemon Omega Ruby but for some reason whenever I try to decrypt Pk Ultra Sun the bat file says "Finished, press any key to leave".
I do have a log file, it says: 04/05/2020 18:01:37,41 which I suppose is the time I tried to decrypt.
Thanks

I keep getting an error saying it can't find content.txt?

 

[uglyrhubarb]

hey, i get following error message when trying to use it:

[TIK WARNING] Failed to sign header
[TMD WARNING] Failed to sign header

am I the only one with that problem and is there a way i can fix it?
cheers

edit: trying over and over again somehow worked for me. problem got fixed

 

[papermanzero]

I tried it with No-Intro encrypted roms. normally after the process it should fit the No-Intro decrypted hash, which is not the case.
So something with this tool is not working correctly.

You can use a tool called "3DS + CIA Rom Script" (Actually it's a collection of tools in one package). This should give you the same hashes as the ones found in the No-Intro database

You can find the tool in the google link found HERE
Tools --> Nintendo 3DS

 

[Captain_Balcon]

Does this work on Android?

 

[eqagunn]

Tested on a few already decrypted ROMs to see if this tool can be used just for trimming.

Worked fine for "Super Mario 3D Land", "A Link Between Worlds" and "Pokemon Ultra Sun".
On the other hand, "TriForce Heroes" reports invalid region in Citra and wont start.

Upon further inspection I noticed all trimmed ROMs ended up with first 256 bytes being overwritten with FF for "HeaderNCSD.bin", "HeaderNCCH6.bin" and "HeaderNCCH7.bin".
3DSExplorer and NDSTokyoTrim don't do these overwrites and end up with a functional "TriForce Heroes".

I asume this tool doesn't support already decrypted ROMs.

I'm getting an error with multiple .cia files

Error -3 from inflate: incorrect data check

I'm receiving an error trying to decrypt Pokemon Ultra Sun:

"NCCH/CCI/CIA archiver and more has stopped working: a problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

Anyone else encounter and resolve this?
