Finally it worked on my pc too! So, I'm happy and impressed! It is wonderful!
BUT:
From the Readme:
Quote: ****IMPORTANT*****
you MUST have installed the latest DirectX dll called 'd3d9x_26.dll'. Sphere wil fail without this. If you have downloaded and installed the very latest DirectX update it should be installed already.
"d3d9x_26.dll" doesn't help you anything! "d3d9x_28.dll" doesn't do the job, too.
It was mentioned that one needs the "d3d9x_30.dll" somewhere in this thread, but I relied on the authority of the readme!
At the moment the shadows have hard edges, but maybe it is because I don't have the latest drivers of my videocard "Radeon X300"!?
