Heya, I'm trying to get the music from this game. I managed to rip plenty CRI HCA encoded files from its install and updates (they were contained in CPK, then ACB files), but the ways I found to decode them all results in scratchy sounds (though one can hear that they are supposed to be sound and not some binary files). Maybe one of you capable of handling this?

Hello HyaHyaT :D
I would be very interested to get the mobile gamerip soundtrack.
but you should upload the archive on other host please.
4shared requires an account.
and maybe anyone would be able to make a Rip.

I realize this is an older thread, but in case the thread creator comes back to check here is a link to the HCA decoder I use and I haven't had any problems with it. Just drag and drop your file (can't recall if it'll support multiple files at once) onto the exe and it should output a wav file.

Hm, these all seem to be the versions of the decoder I already have tested before and the resulting audio all sounded scrambled back then. Which exe did you have success with?

Edit: These are the files directly from the game's server btw (needs VGMToolbox to extract the HCA files from the CPK archives).

Hey, sorry for the late response. I checked out those HCA files but something seems wrong with their header file as they typically start with HCA instead of the gibberish ��� at the beginning. You might be able to find some help on the hcs or zenhax forums.
