■ What is this?
There are two types of clients for Ultima Online: the Classic client and the Enhanced client. The Enhanced client has a wider screen and a more user‑friendly interface, so many people prefer it, but changing the server address is complicated, and there are practically no Korean free servers that support the Enhanced client.
So we created it. Running this launcher will connect the enhanced client directly to the Yeoul Ultima server. The user only needs to click [Connect to Game] once.
Features — automatic server connection, server status (online/offline) display, notice display, account save/auto-login.
■ Supplies
The Enhanced Client for Ultima Online must be installed on your PC. Basic game assets such as graphics, maps, and sounds are large and are not included in this connector. Download the legitimate client from the official EA (Broadsword) website at uo.com. Your account is only needed when downloading the assets, not for playing.
You also need to enable .NET Framework 3.5 on Windows. (Win+R → optionalfeatures → "\.NET Framework 3.5" check)
■ How to use
Extracting the archive
폴더 안의 실행파일을 관리자 권한으로 실행합니다 (우클릭 → 관리자 권한으로 실행)
The Enhanced Client (UOSA.exe) folder is detected automatically. If not, specify it with [Find].
Click [Game Connection] to launch the enhanced client and connect to Yeoul Ultima
※ The files inside the folder (launcher + accompanying dll) must be kept together. Do not run them by extracting only one file.
■ Connection server — you can also use a different one
The default is set to our server (Yeoul Ultima), so just run it and it will connect immediately.
Because of the nature of the enhanced client, the server address is embedded in the program. If you want to use it for another server, you must change the address and recreate it. It's not made to block; if you want to use it on your own server, contact the operations team (questions board) and we will guide you. Feel free to modify.
■ Not possible / Caution
Made based on enhanced client 4.0.117.0. In newer versions or other builds, connection may fail or freeze. If so, let us know on the questions board and we'll adjust.
Due to the nature of the connection method, it must be run with administrator privileges.
The antivirus may mistakenly flag a connection as a risky action. If that happens, add the folder to the exception list. It's an official client you received, so you can rest assured.
Exclusive to enhanced client.
For those using Classic Claw, a dedicated Korean patch client for Classic is separately uploaded → https://yeoulgame.com/board/files/2
