Is there a way to extract 'app.pkg' backup up from disc to usb?

After looking around I am bewildered that I have not been able to find a PC tool to extract pkg's extracted from disc. Does one exist?

Yes, actually I have been making one for the last 2 days and it works great for upacking/repacking/merging/batch repacking/verifying game to updates/file extraction and repack/showing embedded files or extracting single files from the pkg. Also it can dump icon and game background easy so I use that for making wallapers.

It's still being worked on so I've still got stuff to add and then theme it to a nice black or deep purple with fancy buttons. Probably I'll be finished this week and then release it.

What's good about this is there's no need to type anything, create files or anything - it's all done with a mouse. I wanted to repack black ops to remove all the foreign movies and audio and merge the update and used this, it got the game pkg down to 9.76GB and it works perfect.

If you mean from the PS4 itself, ITEMZFLOW game manager will do that for you.

No, because (I believe) we don't have the key(s) for that.
That's why the PS4 has to decrypt and extract that pkg, so that we can dump and the decrypt the files, while the game is mounted/running.

Once done, we can fake sign it and repack it into a fake pkg.

He is asking about the pkg on the BD discs.

OK fait enough, I don't have any original disks and didn't know they even contained a pkg file. I guess you just need to install then dump if you can't dump directly from the disc.
