Dark Souls 3 - Reverse Engineering

This repository serves as a set of tools, resources and collected data related to reverse engineering the Dark Souls 3 game engine and netcode. The focus is on the matchmaking implementation, with the hopes of eventually creating a private matchmaking server.

What can I find in here?

The layout of the directory structure in this repository should be mostly self-explanatory for now. Each sub-directory has its own README which you can visit from the links below.

NOTE: Most of the following is still a work in progress.

• proto - Collection of protobuf definitions
  • dumps - An empty directory for dumping out protobuf messages to.
• tools - Collection of various tools for working with the runtime game or game data.
  • tables - CheatEngine tables used for debugging.
• packages - Rust packages for server emulation.
  • cwc - A port of the CWC authenticated cipher mode.
  • dks3_config - A library containing config structures common to the DkS3 client and server.
  • dks3_launcher - A simple launcher and patcher for the game client.
  • dks3_proto - A standalone implementation of the Dark Souls 3 client to server network protocol.
  • dks3_server - The server emulator.

How can I help?

The work being done here is by members of the ?ServerName? souls modding discord. Check their website for an invite to the Discord server where any discussion around this happens.

I run a Ghidra server containing runtime images of the Dark Souls 3 executable. You can access it by connecting to the Ghidra repository at soulsmodding-ghidra-hosting.uksouth.cloudapp.azure.com.

If you would like write access, please ping sfix#5190 on Discord, either via DM or a ping in ?ServerName?. This server is running Ghidra 9.2, so you will need to build your own distribution or get one from Ghidra, batteries included before you can access the repository.

You can check the issues page for a list of things that are being worked on.
