Please help me extract this UMD.cpk.
Here: https://www.dropbox.com/s/zw6jxspw9kctq8s/UMD.cpk?dl=0
There are movie(*.pmf) and voice(*.dat) files. I need a voice pack (wav or at3 format???).
Thanks for your help.

The cpk script seems to work (yeah it takes some seconds before starting the extraction), have you already tried it?

I don't know.
In case someone wants to work on it this is the header of these dat files:

Code:

48 43 41 00 01 03 00 60 66 6d 74 00 01 00 ac 44   HCA....`fmt....D
00 00 00 4e 00 80 01 7f 64 65 63 00 00 f6 01 0f   ...N....dec.....
5c 00 01 00 61 74 68 00 00 00 63 69 70 68 00 00   \...ath...ciph..
70 61 64 00 00 00 00 00 00 00 00 00 00 00 00 00   pad.............

These .dat files are actually HCA files. The problem here is that these are encrypted.
Maybe you need to work with your extension guessing a little more.

They are the original filenames and NOT guessed extensions.

Either way, these are just HCA files so...
