OUO Test Center

Getting Started

Ultima Online clients from 1.25.30 to 5.0.9.1 are supported, with encryption enabled. We recommend UOR client for a classic experience.

Follow the steps below to set up the Ultima Online client.

Download the UOR client:

Download UOR Client

If you are using ClassicUO, you can use the UOML Client instead.
Extract the archive to a folder of your choice.
Classic UO clients require Windows registry keys to locate their data files. Choose one of the following options to set up the installation path:

Option A - DLL wrapper (recommended): download dsound.dll and place it next to client.exe. It intercepts registry lookups and automatically resolves paths from the client's own directory, making the installation fully portable.

Download dsound.dll (source code)

Option B - Registry file: download uo.reg, edit it with a text editor to set the path where you extracted the client, and double-click it to apply.

Download uo.reg
Edit login.cfg in the client folder with a text editor and set the login server line to:

LoginServer=uo.serpent-isle.com,2593

Use a comma between the hostname and the port, not a colon.
Launch and play.

Server Address

uo.serpent-isle.com,2593

Accounts are created automatically on first login. Enter any username and password at the login screen.
