📋 About This Mod
AkiniKites is a far superior modder than I am and her(?) Alloys Adjustments can make this into a singular small patch.bin

Simply extract the files into your Horizon Zero Dawn/Packed_DX12 folder to enable, and delete to remove.
Apparently if I pack them all together as a single file it only reads a couple of them. If I pack them individually, they all work.
You need to repack your initial.bin with the files in the zip folder.
You can use DecimaExplorer-GUI-Repack release version 2. 7
found here: https://github.com/Jayveer/Decima-Explorer
Make a backup of your initial.bin so you can always undo this change. I made mine initial.bak.
If anyone can explain how to make this change stand alone similar to other mods I would appreciate that or wants to take what I have done and make it their own MOD I am fine with that.
Special thanks to the discord server and user AlexPo specifically.
If anyone wants to repeat and change anything in this mod, here is the process for doing this.
Download a file extractor for Horizon Zero Dawn. The one I know about is https://github.com/Jayveer/Decima-Explorer/releases/tag/2. 7 this one.
You will need to direct the Decima Explorer to the Packed_DX12 directory of your game installation.
Once you have done that it will show all the core files in the game. Including any mods you have in that folder.
click anywhere in the window to select any file and hit control-f to open a search feature.
Find files that you want to edit and extract them to a clean folder.
For this project I have provided an image of the files list I changed as well as the folder structure.
Next, you will want to know what is in these files so you know if you want to make changes to them.
For that, you will need something that can translate the .core files that you just extracted from the games .bin files.
https://github.com/AkiniKites/HZDCoreEditor is one that seems to work. It says editor, but it is really only a reader.
AkiniKites did not create a packaged version of this, so I had to package it using Visual Studio 2019. I have attached a copy of it in the optional files of this MOD.
I have provided an image of me using this to find the information that needed to be changed. Discord's AlexPo is the person who explained to me how to use this information. In this example I want to change the ammo capacity. The ammo capacity is stored as an array of Int32 values. I can use this information to find those values in in a hex editor.
AlexPo pointed me to this hex editor https://mh-nexus.de/en/hxd/ and I have provided an image of me using this to find the values that I wanted to
