While I don't have an answer for the Switch version at the moment since it uses a currently unknown key, I did a quick check for the Steam PC version, and it seems to use a DXLib archive with a simple XOR obfuscation.

Here's a QuickBMS script that I wrote up to decrypt those: https://raw.githubusercontent.com/Random...ie_XOR.bms

Afterwards, you can simply use aluigi's "Heart Of Crown" QuickBMS script from here to extract the archives' contents: http://aluigi.altervista.org/quickbms.htm
