How to Use Hxd Hex Editor for Games

Hi folks, so I just wrote this out on someone else's thread, and while there are quite a few of you that'll already know how to do this, a lot of people still don't. So, I figured I'd post what I wrote as a  tutorial and expand on more here for the benefit of the community. This can be used to change superstar names, arena names... pretty much any text in the game can be changed through editing the string.pac file.

@pozzum already created a great tutorial on creating your own text strings here, which you can create and then link to in your pofo to change your superstar's names and I'd advise you to fimiliarise yourself with that video first. However, this tutorial will focus on straight-up replacing text in the game, focusing in this example on replacing all instances of a superstar name so it's changed in the Creation Suite as well as elsewhere

NOTE: Once you edit your string.pac, downloading any future proof string files will then overwrite your current one. However, once you know how to create/edit strings you will no longer require any updates as you can add stuff in yourself (not to show any disrespect, in any way, shape or form, to the guys working on the future proof strings as they're doing amazing work, and some international users may still require these updates).

To edit text strings, you'd firstly need to have the future proof string installed, as this will show text strings rather than code like the original string file. Download HxD and open the string.pac file with it. Then do the following:

1) Click near the top of the document. Hit Ctrl+R to bring up the Replace menu. Set the Datatype to Hex-values and the Search direction to All. - NOTE: Alternately, if you're looking to replace a single string, you can hit Ctrl+F to search for that string, then type over it - refer to pozzum's video for this in more detail. NOTE: If the text you want to replace is the same amount of characters as the new text (say, DAMIEN SANDOW TO DAMIEN DAMIEN, random example but both 13 characters each) then you can just put your search for/replace Text-string instead. Otherwise, set to Hex-values and follow the next few steps.

2) Open this page - it's basically a text string to hex converter. Type in the text you want to replace in all caps (make sure it's accurate or HxD won't find it!). Hit Convert then hit Select, then hit Ctrl+C to copy the code. Paste it into the Search for box back in the HxD Replace menu.

3) Repeat step 3 to get the code for the text you want to replace it with and paste that code into the Replace with box HxD. NOTE: The text you want to replace it with can be no longer than the original text. It can be shorter or the same length, but not longer.

4) Once you paste that into the Replace with box, if the new text has fewer characters that the old text, then you're going to need to replace any missing characters with blocks of 00s. So, for example, if I wanted to replace DAMIEN SANDOW with BUTT MUNCH - the original text is 13 characters long whereas my new text is only 10 characters. So my text in the boxes would look like this:

    Search for: 44 41 4d 49 45 4e 20 53 41 4e 44 4f 57

Replace with: 42 55 54 54 20 4d 55 4e 43 48 00 00 00

5) When you're done there, hit Replace all and HxD will replace all instances of, in this example DAMIEN SANDOW in the file. That'd mean it'd be changed in the selection screen if that was his name there and also in the Creation Suite or wherever else it may appear. Hit save when you're done.

6) Navigate to your 2K16 installation directory and to the pac folder. Scroll down and you'll see a file named string.pac.bak - this is a backup file that HxD made before saving, so put this somewhere safe and if you need to back up then delete the .bak part from the name and then copy/paste it back over your string.pac file. NOTE: You'll need to move the .bak file to another folder as the game might still try and read it rather than your current string.pac file.

That's it, now try it in game You can edit all sorts of strings. If you look right at the start of this video you can see I've also edited my roster names, changing SUPERSTARS to WWF ROSTER and DOWNLOADED SUPERSTARS to WCW ROSTER. If you can find the text in the file, it can be modified!  Always remember, your replacement text must be, at maximum, as long as the original text string - no longer. As always, back up your files for future reference!
