This is a simple parser written in Ruby. It has the capability to check system firmware version requirements on a PKG file without downloading the whole thing.

To use: you will need to install the http, and bindata gems.
Git clone this repo, and follow instructions in readme: https://github.com/FennyFatal/param_sfo_tools

from where does it pull the db ?

It downloads the first 2MB from the provided pkg URL, then extracts the param.sfo, and parses out the information from there.

Code: 
~/ps4tools/param_sfo$ ./get_sfo_info.rb http://gs2.ww.prod.dl.playstation.net/gs2/appkgo/prod/CUSA00016_00/3/f_532be3d0389a65b89ecbd892f96a361dce5d55b011953f7dd3803a110bd6e2a1/f/EP0001-CUSA00016_00-WATCHDOGS0000000_0.pkg

In the above example the PKG file requires 1.61 system FW.

COOL, how do u extract the title name ? since each game have its own offset where it holds the title of the name

i made here, a little script that pull out all the cusa names in the same directory.
https://ayakalounge.me/threads/nice-site-to-find-update-packages.1164/#post-12184

could be great if i could also add names to it . but i am not sure about the offset that u use. perhaps u could do that with python ?
im not good with ruby.

I scan for magic in param.sfo, then I parse the header. You can see the structure of the header in SFO.rb.
You can calculate the offset of the value you are looking for by parsing the struct that contains each entry which will tell you the start and end offset from the SFO magic value.

i am not to good with ruby, i am pretty bad actualy (dont know how to code it)
i think u should add flags with ur code such as -u for url or -l for local. and be able to parse those info from a local files / files/ folder

It will actually work that way now.
