# Diablo II: Resurrected - Offline Patcher

A simple tool that remaps & bypasses *Diablo II Resurrected* module and then continues to patch connection functions to allow local gameplay. 

More information about the crc32 bypassing and remapping can be found in my '[Bypassing World of Warcraft's Read-Only Code Protection (crc32)](https://ferib.dev/blog.php?l=post/Bypassing_World_of_Warcraft_Crc32_Integrity_Checks)' blog post

# Usage

.NET Framework v4.7.2 is required, which you can download at https://dotnet.microsoft.com/download/dotnet-framework/thank-you/net472-web-installer

Download the latest release *(or clone a project and build using Visual Studio)*

Copy **both** `D2ROffline.exe` and `patches.txt` to your Diablo 2 Resurrected game folder and then double-click `D2ROffline.exe` to start the tool.

That's about it!

*NOTE: For those who want to add (or remove) patches, open the `patches.txt` and start modifying them.*

## Custom Patches

There is a neat little feature that allows you to use the `patches.txt` file and create your own patching rules, the `patches.txt` file **MUST** be in the same folder as the executable!
This allows you to create your own patches.
