I would like to extract the Music from "Super Robot Taisen 30" that I purchased on STEAM, but the HCA file seems to be encrypted and I am having a hard time decoding it correctly. When I open it in a binary editor, the header is HCA, and when I open it in foobar2000, it recognizes the length of the song, but when I try to play it, it doesn't decode properly and only plays strange sounds. Please tell me how to get the key to decrypt the HCA.
These are the HCA files that are encrypted and the files that seem to be related to them. https://mega.nz/file/vaRkiLqa#BJ_f3tTRU3vxnf5AeUP6PIchbGgegkMaRcCpKxy7cBI
Thank you.
