The code is open source, you can create the equivalent for Mac from source code.

Been trying to decrypt and i just don't get it. I put the files in a folder and add a game with them. I press the decrypt file and all it says that its finished but never gave me a file. I also tried putting .3ds at the end of the games name file and still nothing. What am I doing wrong? Yes i deleted the whole folder and started fresh multiple times. Please help!

Hey, I'm having the same problem as a few other users, and was wondering if anyone could help? I'm trying to run a .3ds game file through the decryptor, and I get the same error. I've looked through some comments here but couldn't find a solution.

The log file says this at the end:

Parsing Manual NCCH
Traceback (most recent call last):
File "decrypt.py", line 421, in <module>
File "decrypt.py", line 263, in parseNCSD
File "decrypt.py", line 278, in parseNCCH
File "decrypt.py", line 74, in __new__
ValueError: Buffer size too small (0 instead of at least 512 bytes)
Failed to execute script decrypt
[MAKEROM ERROR] Content 0 is corrupt


If there's any way someone could help (or if anyone at all has any advice) please let me know!! I'd really like to start streaming this game to some friends. I can send the entire log too somewhere, if needed- being a new user, I wasn't able to send the whole thing through here yet. Thank you!

How to only decrypt and maintain .cia format?

Looks like either the script or the makerom program doesn't work with roms that have an exclamation in the title like "Aikatsu Stars! My Special Appeal (Japan).3ds"

Comment out or remove the line that deletes the intermediary decrypted CIA during CCI creation.

for %%a in (*-decfirst.cia) do del "%%a" >nul

Is it possible to create a GUI for the tool?
I'm using Winlator (a Windows emulator for Android) and it can't run batch commands.

Sadly is a lot of work because the batch file run a lot of commands, so no easy to create a GUI for that.

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

How do i use it? I don't know a lot about tech

Guys make sure there are no weird characters in the files, the program for some reason can't do it's work that way, just put the title ID as the name.
