ROM Hack [Release] FunKeyCIA - make GOOD cias from eshop content, no tickets needed!

[cearp]

There seems to be an issue with make_cdn_cia too. I tried creating cia's for the Themes and Theatrhythm Final Fantasy: Curtain Call dlc of which I own keys from.

It funkeycia downloads the content correctly but generates and 0byte cia file on both windows and mac. the title IDs are 0004008c000fd500 and 0004008c00008f00. they both have a lot of content files.

on my mac make_cnd_cia throws an "Floating point exception: 8" error.

yes, there is a newer version of makecdncai, i have a compiled build for mac i can share in 12 hours.
with lots of content files, the old makecdncia (the one i included) can go bad
don't worry about it

Noice, finally got it to work! Was able to compile a "fixed" Decrypt9 based on the suggestions of others in this thread. I have successfully re-encrypted a title key, pass it through the tool, download/create the CIA, and install that CIA. Thank you so much for sharing this!

I've had mixed results. It seems to be that games that I had already installed before using a "bad" cia are giving me cert errors, but games that I try for the first time work fine.

I tried the same cia on 2 different 3DSs and it worked on the 3ds that I had never installed the bad cia on.

Is there a way to unregister the bad cias from my title lists?

Edit: Confirmed this the was issue. Fixed it by deleting the ticket using the latest version of FBI as recommended by Drethin.

You can delete titleid's using the latest FBI

This worked, I deleted the ticket and tried the CIA again. It installed correctly.

Did you "fix" Decrypt9 to get it to work? If so how do I compile it once I've downloaded the source and made the change? I've been poking around for a while and can't seem to figure it out.

There's no need to decrypt the contents. DecTitleKey.bin from D9 already contains the decrypted contents from title.db. However the process of re-encrypting them is decrypting them a 2nd time, then encrypting the result, causing the issue.

Credit goes to @shinji257 for finding it.

Anyways the easiest way to fix it is to edit line 24 in titlekey.c and change AES_CNT_TITLEKEY_DECRYPT_MODE to AES_CNT_TITLEKEY_ENCRYPT_MODE

This however breaks the decryption function.

Thanks a lot for that solution.
Can someone upload a fixed version of Decrypt9WIP? I dont know how to compile it

And another question... Once we have the enctitlekeys? How can we see the Keys for each title id?

Thanks for all

Yes, I don't know I'm allowed to upload it, but PM me and i'll link it you.

 

[Shadowtrance]

I can do it if someone tells me wtf needs changing.

nvm i found the issue. build coming up!

you can rename the encTitleKeys file to decTitleKeys and get the list using PlaiCDN's checkbin option.

D9WIP with (apparent) fix.

Thanks!!!


And the Last question... If I install these New "legit" cias, we need al updates seeddb.bin or its unnecessary?

 

[BerserkLeon]

Since I am not able to compile my self, could someone else provide the windows exe:
https://github.com/YodaDaCoda/make_cdn_cia

not sure if this is x64 or x86 but...​

 

[makke007]

So i got my encTitleKeys.bin
How do i get my Keys out of this now ? I don't find any Option for that in Decrypt9 any advice ?

Use the python script in the OP

Open a hex editor, search for the title ID.
The following 16 bytes are the title key.

If you generate a CIA that required a seeddb.bin to decrypt, it will generate a CIA that requires you to visit the e-shop to fix as these are non-cryptofixed CIA's.

I'm not using a ticketdb though i just have my encTitleKeys.bin file and it has multiple Titles in it

Ooh oh yeah, recommend to dump your ticket.db with decrypt9, if they are your keys. If not, wait for me or someone else to make a script to show them in plain text, or use the bin file in FunKeyCIA

 

[Drethin]

Here's a script that should take an encTitleKey.bin show it in plain text, I don't really know python so good luck I guess? I think it needs python 3.
