Some weird .hca files

Post by festergut »

Hello, I came across a .awb file from a mobile game based on unity3d. I extracted it and got some .hca files, but things went weird. These files have head "c8 c3 c1 00" instead of "48 43 41 00", and this tool still made it to extract the files to .wav, but they can't be played correctly. here are the hca files:
hca.zip


and this is the awb file(might be useful to find a key?):
cv-10105.zip

The B file is an "@UTF" file that I guess it's related to the CRI framework (the same framework used for the CPK archives), I don't know if the CRI tools can handle it.

Yeah you are right, and they are similar to the files in PSO2. I just found the encryption key of these .hca files in another asset by accident, and now they are all decoded. Thanks for reply :D

It seems that the head "c8 c3 c1 00" means new version of .hca files. If there is no encryption, CRI tools might work.
