Taking a look at Shining Resonance [PS3]

I wasn’t able to extract the files, when the game got released, and 8 months have past.. I think I’ve leveled up since…I somewhat extracted the contents and at least it’s named properly by event and in plain SHIFT-JIS text format but on…SDAT?? that weird…sdats should be encrypted…and images uses the common DDS format.

the question is can it be re-packed on a lower version of CPK?

I just got curious since a friend mention it a while back, but WTH? 6465 files?
