There is a basic DirectDraw support included in the Colibri PXA BSPs. However there are some restrictions, some of them are related to the Windows CE DirectDraw support, others are related to the BSP implementation.
Wrong surface pixel format: With LDDS=18, BPP=16, the Direct Draw surface descriptor reports a 565 pixel format, but it is 555.
Primary Surface Flip: This is not supported by the Colibri PXA BSP.
Blit: Blit from primary surface to offscreen surface generates exception.
