The new alpha has finally been released. Some features from the old version are missing, so it may be a little disappointing at first, but this version should be under much more active development than the last since it's totally rewritten in a new language with better development tools available (now C#, rather than the buggy old Turbo Delphi).
And there's some new features that should hopefully make up for the initial missing features, such as Linux support! Using mono GameSrv should run under most Linux distributions, and dosemu provides the 16-bit door support
