If you are using DirectX 9b managed code, I have ported quite a few of the demos and they are hosted @ http://cc.borland.com/ccweb.exe/listing?id=21147 .

I started work on getting DirectX 9c managed code demos ported ( particularly the new GUI stuff ), but have not had the time to finish them. I think the bug in the earlier version of Delphi 2005, may have also stopped me as well.
