NPK Archive Unpack [Forever 7th Capital]

Post by akderebur »

Hi,

I have some NPK files from a mobile game developed by NetEase. I was able to extract the npk archives in other NetEase games, using offzip. They were compressed with zlib. This time it seems like the compression is something else. Hopefully it isn't too hard to see. I would appreciate some help with this.

Sample files : http://www.mediafire.com/file/gtbmif2c9 ... Sample.rar

Thanks.

It looks like the TOC (the information about the archived files) is encrypted, that's why my nxpk.bms script fails.

I see, encryption makes things complicated for me. Maybe I will return to this game later.

Thank you very much for taking your time to take a look at the samples.
