Interface source
InterfaceClassic/Classes/UnrealScript classes for client windows, including inventory, skills, quests, and zone titles.
Shared resource / Client interface
Explore Lineage II interface sources, XML window layouts, and bundled editors in one P542 development archive.

Inside the download
Interface P542 brings together the InterfaceClassic UnrealScript source tree, NWindow API classes, L2Editor build tools, and a 542_XDatEditor folder with XML interface definitions. It is a useful reference for developers exploring how Lineage II client windows connect their layout, event handling, and compiled interface files.
The archive includes InterfaceClassic.u and InterfaceClassic.xdat under L2Editor/Build, alongside editable .uc classes and the samurai_crow XML layout set. Browse the content previews below before downloading the original RAR. P542 is the archive’s version label; a successful build or compatibility with your particular client has not been verified.
