Posting here because I'm at least using your same methodology if not the exact script. That's been really helpful - I was struggling with the right syntax unpacking the XCI with hactool before I found this. Description: Embark on an exciting adventure around the world Join Mario in a massive 3D adventure around the world and take advantage of his incredible new abilities to collect the moons that power the Odyssey flying ship and stop Bowser, who is planning to marry. However, I've been jumping through the source code and using the commands in there as an example. 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. 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.

As I understand it, the nca files are encrypted, and I need the title key to decrypt them. I'm able to unpack the XCI into nca files, but I can't proceed any further. 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've dumped Cave Story+ using gcdumptool and I'm trying to unpack the game data. 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?
