Hello there,
I searched for a way to unpack system CIAs to do some RE on these, but I can't find a way to do it. Is there any way I can do that ? |

I'm quite noob here but i'd like to try to answer this.
I found no way to directly decrypt the system CIAs that get from Ninty's CDN. Even with decrypted title keys the decrypted content still seems encrypted/a mess. The only way for me now, is to install the CIA, to the EmuNand, then decrypt and dump those System Apps with RxTools. Once it is dumped, you could see lots of .app files in your SD card root. Just look for the title id you'd like to see, it should be fully decrypted, and just with ctrtool or whatever you could unpack it. Maybe with a later release of rxTools it would allow users to just decrypt and dump several ones that users asked and written in a text file. If there is any way to fully decrypt the contents i'd be quite happy to see it. |

Actually, I found that Decrypt9 has an option to decrypt CIAs, and it worked.
Just use the latest version of Decrypt9 and put the CIA in a folder "D9decrypt" on your SD card, then start Decrypt9, there is an option to decrypt CIAs. |

Posted by Mrrraou Thank you for that. I had to admit Decrypt9 is better option for decrypting things.. So next time i could try it when don't want to install the CIA. |
