UO:98 is an extension to the UO Demo released by Origin Systems in 1998 on the Ultima Online:Second Age CD. The UO Demo (demo) is an offline tutorial for Ultima Online. The Demo featured only the town of Ocllo, and a quest that a player could complete while learning about the Game and Client.

UO:98 is an attempt to bring the UO Demo mainstream by patching the Demo into a fully functional and administrable server.

The majority of the necessary basework via has been available for some time. The project took UoDemo+ well beyond the chains imposed by having to make direct hacks to the UODemo.EXE, patches can now be applied or even un-applied during run-time; and new code can be added outside the executable and hooked to existing functions.

A new project called Sidekick was developed in Visual-C++ to be loaded by UoDemo using the UODEMODLL env variable. This Dll loads both Batlin's UoDemoDLL (In addition to some great patches, the Wombat API for in-memory patching), and also loads a C# managed DLL called Sharpkick. Sidekick acts as a Marshall between the unmanaged Borland C UoDemoDLL, and Sharpkick a Managed C#.Net DLL

Currently all packets can be intercepted and replaced or handled directly within C#. This gives the ability to handle the login sequence very elegantly within C#, and with access to all of the .Net framework for XML handling and file IO for account name translation to account numbers, which are accepted for login by UoDemo+.

UO:98 unlocks many of the features that exist in the UO Demo such as the ability for others to connect with a regular UO Client, the ability to use the built in staff tools, and the expansion of the playing world to the entire map, and world saving. UO:98 also adds new features such as an accounting system, full world decoration, and support for later UO Client versions.
