UOSL

Ultima Online: Shattered Legacy (UOSL) is the pre-alpha version of Ultima Online from 1996. UOSL is the first graphical Internet MMORPG.

original client

This repository contains the following projects:

  • libuosl: a library to access the data formats of the original client. It can retrieve graphics, sounds, map information and everything else needed to implement a server or client for UOSL.
  • ViewSL: an application that uses libuosl to browse the client data files, e.g. for viewing ingame scenes, listening to sounds, searching for graphics by name and other features.
  • SLClient: a custom client implementation that uses the original client data files through libuosl. Rendering is done using OpenGL 3.2.
  • JPhex: a server emulator for UOSL. It can be used with both the original client and SLClient. Behavior of items, spells and NPCs can be changed at runtime using Ruby scripts.

Project Status

  • libuosl: mature, can read all of the client's data files and almost every field in all data types is known and supported
  • ViewSL: mature, can view most of the client's data files
  • JPhex: beta, has support for all game mechanics but not all scripts are implemented, e.g. some items are missing and the NPCs are not very smart yet
  • SLClient: pre-alpha, I'm mainly doing experiments and prototypes here, especially the rendering is very slow because I'm currently focused on other parts
