Can the Dreamcast Dev Box & Utils support later versions of MS DirectX?

I wanted to know if I have a Dreamcast Dev Box with the R9 SDK & the Windows CE 2.1 SDK for Visual C++, would it support the DirectX 9 SDK for Visual Studio?

The version that is supposed to be for the Windows CE SDK is 6.0, but If I develop applications with the latest DirectX SDK, would they work on a normal Dreamcast?

The last DirectX SDK version for Visual Studio 6.0 is 9.0 Update (Summer 2003).

 

oh well....whatever...
