D2R-Offline

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.

Setup

Installation

1. You will need the Diablo II: Resurrected game files.

2. You will need .NET Framework v4.7.2, which you can download at:
   https://dotnet.microsoft.com/download/dotnet-framework/thank-you/net472-web-installer

3. Download the latest release (or clone the project and build it) :
   https://notabug.org/viperultra/D2R-Offline
   Unzip and copy both D2ROffline.exe and patches.txt to your Diablo II: Resurrected game folder. They should be in the same directory as Game.exe.

Run

1. Double-click D2ROffline.exe to start the tool.

2. A cmd window should open and begin the patching process, then prompt you to hit any key to continue, then the game should open. You can then close the cmd window.

3. When loading a character, use the TCP/IP button and host a game, double clicking the character name or clicking Play will not work by default. See the -FixLocalSave argument under Usage if you would like to edit your saves to play in offline mode (including act1 to act5).

Please see the FAQ if you have any issues.

Usage

Arguments

You can run D2ROffline.exe with arguments to solve some problems.

-FixLocalSave

.\D2ROffline.exe -FixLocalSave This will update your save files to allow you to play your characters in single player mode (act3 to act5 included) instead of hosting a TCP/IP game. This argument prevents the game from loading and will just patch your save files.

-UpdateKeyBinds

.\D2ROffline.exe -UpdateKeyBinds This will sync your keybindings between characters.

-Delay <delay in ms>

.\D2ROffline.exe -Delay 35 This will change the delay amount when patching your game, default is 25. Use this and try different values to help with crashes after being in-game for certain amounts of time.

"Game.exe file path"

.\D2ROffline.exe "C:\D2R\Game.exe" Use this to specify a path to Game.exe if you're not running D2ROffline.exe from the same directory.

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.
