About
CrossUO is a cross-platform client for Ultima Online, in active development. It currently supports Windows 7+, Linux, and macOS, with Raspberry Pi and a WebAssembly browser version in progress. Its renderer is presently based on an older OpenGL 1 implementation that is being reworked to enable further platforms and better graphical performance. It is licensed AGPL-3.0-or-later.
