SteamEngine is a new open-source UO server emulator coded in C#, which can read and run Sphere scripts. It`s domains are supposed to be extreme customizability even for non-programmers, and a clean and readable codebase. The project is now abandoned. The "intended for the public" phase ended long ago. The "OldCode" repository is that (if that still works). Then for a while we intended it for the UO shard moria.cz, but that didn't succeed either, and the shard is now defunct. The last commit of this phase is r904 in "SvnCode" repository. Lately I've using the codebase for experiments with in-memory transactions. First part is abandoning NANT for building and moving to VS 2015. That's done in r922. This is the last functional code. After that the transaction stuff is added which basically means the server is broken. Ultimately I've moved to GitHub, where the development may or may not continue. We'll see. This is a final goodbye.
