@Meowz, no idea about SDK update. As for getting the interface to Direct3DDevice7. You need to have the SDK expose the instance it is using, or you can combine it with SDK. Hence the need for SystemProperty.
If you want to program DX7 from scratch that is much larger topic, and way beyond scope of simple message.
