Ok, I was doing it wrong, Proper option to launch Transfusion with DP is "-transfusion". Now it has proper keybindings and map list, but yeah it has screen shacking and HUD is kinda broken. I will dig DP source code and see If I can fix that.

What is the latest version of Transfusion resources 1.1beta3 or 1.05beta2? Logically it should be 1.1beta3, but it has older files? I'm I missing something?

I can take care of it, but where I can find source code of current binary (1.1beta3) – in repository there is only code for gameplay in quakeC and source code for tools.

As I understand there is no build for OSX, so I've downloaded 1.1beta3 resources and run it with latest Darkplaces (20140513) using "-basedir" option. It works kinda ok, but some keybind options are missing and in map selection there are quake maps. How can I fix that?
