Fighting spirit (*.pkg)

Post by giles_tesla »

Hi! Aluigi.
The effect of this game is very cool, strong Oriental ancient military color. I try to use offzip opened them, but there is no good results, of which only can obtain larger file open very few DAT file, I'm not sure what they are using compression, and how to open them. I know maybe this game not too interested in you. Can you help me if you can take a look at the game PKG file?

There are no filenames because I guess the final part of the archive is where these information are contained and are encrypted.

But don't know why, for a small amount of files after the script is no longer work, because of encryption?

c1467147153_0.pkg unpacks 16Mb and c912410164_0.pkg 3Mb which are more than the original size.
Nothing wrong here.

Yes, extract small file seems to be no problem, but the package contains a lot of more than 200 MB file decompression can only get a few files, the size of I unzip a 600 MB file, for example, actually only obtained 30 MB

I look at some of the PKG file, I found a lot of size in more than 80 MB file head seems to have a lot of different, the same script may not be able to open them, and if unable to get name, sort out these files will be difficult, I think you can give up.
