Hello,

I'm interested in extracting the game data.

Samples: (expired)

Thanks!

It's a PKG CNT format in use on Playstation and I think it's a sort of Sony native format (custom ISO) and not a format of the developers.
Exist no solutions, some weeks ago I made a script able to extract the only refrenced and non-encrypted data:

I see, so you mean it's not possible to extract the content like music since it's encrypted?

The sample is not big enough to see after 0x14b4244, but yes it's for sure encrypted

Could other files be of use? To help decrypt them?
