Help with High School DxD(PSV) bin files

[oukaitou]

Here's the full bin file
https://mega.nz/#!QEVjhbqa!8uz9LnCM5C-x ... h1HcqmY-Z0

I've tried to find out the format but no good. So I searched files from the bin file to see if I can extract them directly.
I found some json files, they look like LZSS compressed files but I don't know how to extract them.

physics.bin

and extracted file may look like this:

physics.json.bin

Need some help, thanks.

grp.bin seems just a raw container without any reference to the files archived in it.
That means you have an index file with such information in the same folder of grp.bin.

Regarding the compression there are no good news too.
It's not the original lzss and not a different setting of the algorithm.
In any case it's not available in quickbms.

Thank you for the answer, I'll look for other ways.
