I've taken this down for now. Expect a new version, intended for use as a dedicated server (and compatible with the unmodded 1.08!) soon. Well, soon-ish, anyway.
If extracted into the directory where SRB2 lives, it should work without too much messing about; however, if you place it elsewhere, you'll need to point it in the direction of the game executables using the Game Versions tab. You can also use this to add support for other versions: for example, FD 1.09 could be added to the list, for those lucky testers out there.
New in v0.80:
Bugfixes.
Game Options tab. Sets video and audio options, and other bits and pieces.
Interface was cleaned up a good deal. No fancy graphics yet, though.
