Adventures of Mana (Vita) .MPK extract

[v033d]

Hello. Could someone please try to create a script to extract the files from the .MPK containers from Adventures of Mana for Vita? I tried using the script for Dissidia Final Fantasy Opera Omnia, but it didn't work.

Thank you.

Your file is encrypted, decrypt it first.

Strange, I thought I had decrypted it, but apparently I didn't. In any case, I have updated the first post with the decrypted file. Thank you

I'd like to have this figured out as well. A bunch of models I'd like from it!

Is it really decrypted?
I only see the "mcfa" magic and everything else from offset 0x10 is obfuscated (not really "encrypted" because there are some sequences of same bytes)

Trying to reverse Androïd ELF to understand how "mcfa" works, but I am noob.
Seems that there are complete Lib functions to manage MPK files :

Not easy to deal with it, I suppose.
