The EC is written in the programming language Lua and uses XML to control interface layout. You do not need special software to interact with either .lua or .xml file types. Notepad or another text editor will work just fine. However, some of the graphics files use Direct Draw Surface format and .dds files may not work with all image processing software. GIMP is recommended for image processing as it is both free and can work with .dds files.


Within the client's installation directory, normally something like

This PC> Local Disk (C:)> Program Files (x86)> Electronic Arts> Ultima Online Enhanced> UserInterface

is a file named Custom_UI_Documentaion.zip


Once unzipped, this file will produce a hyper-linked document providing instructions on how to modify the Enhanced Client.
