Creating an unpacking tool

[KoSThem]

I was looking for some help in creating and unpacking tool to unpack .pak files. I know c++ and I think I could do it in that but I'm not sure where to start. I have winhex and I know how the files are packed. I can follow the comas ect. When they unpack I want them to form into csv files.

Now this is what I need help doing. I don't know how to bring the information in from the data pak. I assume i'd do it using winhex, but if I make .exe file to do this, can it open winhex and then take the data from there? Also, when I get to that I don't know if I can use the set data on the right that has the characters, or should I go off the hexidecimal values and program it to pick the hexidecimal and sort from there and output the numbers I want. And then my last question, I'm not sure how to change rows and columns on my cell format via C++ for the output, would I do this with vectors or just get the whole thing in a matrice and output the matrice into cells?

I'm doing this for making a private server of dekaron with the latest korean files.

Thanks for the help.

It is absolutely abstract what you want to do.

Did you decompress the files already?
If so, how does a hex editor come into play for any purpose other than looking at the data? Why would you “bring information in” using a hex editor instead of just loading the file from your C++ code?

Do you only want to look at the data or do you want to modify it? If you want to modify the file you must also create a packer.


If you already unpacked the data, again why not just make a C++ parser to organize it into an Excel sheet?
What formatting of cells?

The game version has all of its data in a .pak file. when you unpak it, its best unpacked into a spreadsheet. I don't know how to infile data from the .pak file is what I'm saying. I use a hex editor to view the data yes. I assume when I figure out the unpacker, the packer should be relatively easy.

If you have the unpacked data, make a script to load it, parse it, and output it in Excel format.

kosthem, you want to be able to view the contents of a pak file? Doesnt this just require you to find out how the game does it and emulate this routine. Reversing the unpacking routine of the contents of the .pak file

There's several different game file unpacking tools out there:

Game Extractor
Multiex Commander
Dragon Unpacker

Those are the more popular ones I think.

When you unpack the data.pak its gonna be a bunch of folders and CSV files,if you want to edit them,its the same as in Winhex ,only that u use microsoft excel to view the file,i suggest you use hack scripts instead of editing the csv file cause everytime you want to edit u must unpack-edit-pack .
