I removed the exe files because my host has limited storage. Maybe you can compile it without modifying your Delphi, try adding D3D8 folder to Project->Search Path, that way it will only affect the current project.
In the next versions I'll try to upgrade it, I never programmed in DX9, but I think its easy to change.
About Newton, I already tried it, but removed it because I has having some problems with colision with multiple terrains. However, the LEAF engine has it own colision/physics engine, its very basic but for most games is suficient.
I'm planning lots of more features for the next version, including sound and better physics, and more 3d model formats.
Right now, I'm adding some screenshots to the site.
