Introduction

Welcome to the Conquer Online server development and client modifications wiki. This wiki is hosted publicly using Git, published using mdBook, and maintained by the open source community. Pages on this wiki cover topics such as server-client message types, cryptography, client file formats, constants, system overviews, and more.

To participate in this collaborative effort to document Conquer Online development, the following rules must be followed:

• Articles must be written from a neutral point of view.
• Authors must respect each other, and not engage in personal attacks.
• Authors must not publish pirated programs.

Please read up on the code of conduct found in the root of the repository.

Verification

Statuses are used to indicate how reliable a page is / what the source of information is. Specifically, if information has been gathered from a community source, such as a private server project, then the status should be unverified until the server is run and the behavior can be at least observed.

• 🚩 Incomplete: The source is unknown and the information is incomplete.
• ❓ Unverified: The source is unknown or cannot be verified.
• ☑️ Assumed (Observed): Assumed by observing the behavior in the client.
• ☑️ Assumed (Soul): Assumed by reading the leaked client source code from TQ.
• ✅ Verified (Client): Confirmed by reverse engineering the client binary.
• ✅ Verified (Server): Confirmed by reverse engineering the leaked server binaries.

Sections

This wiki is broken up into multiple sections:

• Algorithms: Calculations made for attacks, rates, skill distances, and more.
• Constants: Hard-coded constants found in and across messages and the client.
• Files: File formats and definitions for various content types.
• Network: Message structures and client-server networking.
• Renderers: System descriptions for rendering content in the client.
• Security: Cryptography and security around networking and content.
• Strings: Details on strings and restrictions on inputs.
