Grepping for 02e9 in decimal gives:
#define D3DERR_ZBUFF_NEEDS_SYSTEMMEMORY MAKE_DDHRESULT(745)
I'm not sure it makes much sense though.
Native creates a RGB device, which is a software renderer and needs system memory. Kinda annoying behavior. I don't think we want to replicate it, one reason being that we don't actually implement a software renderer.
