ROM Hack RELEASE Extract NSP, NCA, XCI, Update all in one tool for LayeredFS

-i highly recommend Plague Mod you can easily switch donor title right on console.
-you also can use this Website to patch them.

I tried with "Pokemon Quest" and it worked but saving doesn't work, so "Happy Birthdays DEMO" doesn't work with version 1.5.0:

Maybe you know a donor that will work, and no "Fortnite" doesn't work (crashes when auto saving a the start).

Hello. I'm sorry if this is obvious, but can anyone tell me, or point me to a tutorial for, how to get the title key for a given game?

I've dumped Cave Story+ using gcdumptool and I'm trying to unpack the game data. I compiled hactool and then ran through PRAGMA's tutorial to extract the keys from my switch; verified I have all that working as best I can (given I'm still new to this). I'm able to unpack the XCI into nca files, but I can't proceed any further. As I understand it, the nca files are encrypted, and I need the title key to decrypt them.

Is this something I'm supposed to be able to determine on my own, given I have the original cart and XCI dump? or is this one of those things I have to "find"? If the former, can anyone please give me a hint on how to do this? Heck, even if the latter a hint would be appreciated.

Thanks!

Oh, and I should mention that I'm actually not using the NCA-NSP-XCI_TO_LayeredFS.bat file for this as I'm running Linux. However, I've been jumping through the source code and using the commands in there as an example. That's been really helpful - I was struggling with the right syntax unpacking the XCI with hactool before I found this. Posting here because I'm at least using your same methodology if not the exact script. Thanks again.

NCAs that come from XCI don't need title key except updates.
NCAs that come from NSP needs title key.
If Secure folder from XCI contains *.tik file then there should be update game NCA in there that needs title key.

Now where you can find title keys ?
When you extract NSPs you get *.tik file that contain title key, also some XCI carts can have it but it's for update nca not for base game.
Open *.tik file with any Hex Editor and
look at 0x180, there is it.

Thanks, that clears things up quite a bit. Appreciate you taking some time to explain.

Unfortunately, I'm still having trouble getting this extracted. Using your :ExtractDecryptedNCA_Folder code as an example

$ ./hactool /home/user/games/switch/extract/97e31c6e7b60b1effcc89f6bc608e9b6.nca -k keys.ini --romfsdir=/home/user/games/switch/extract/romfs --exefsdir=/home/user/games/switch/extract/exefs
[WARN] prod.keys does not exist.
Invalid NCA header! Are keys correct?
Done!

Guessing I must've missed something with the keys. I'll research that some more and post back here if I hit another wall.

Thanks again.

I didn't work, and I also tried to install the .nsp version of botw and got "0x00014005" error, so I'll stick with version 1.0.0 for now, thanks to all for your support, bye.

 

[crstofer]

Cart 2 support?

 

[sergio_prado]

Theres any known way to repack updates/games back to .nca or .nsp?

After fiddling arround some time. I redumped my keys and it worked just like that. I guess I corrupted my keys somehow.
