--- Comment #11 from Stefan Dösinger stefandoesinger@gmx.at 2008-03-03 18:17:09 --- The problem isn't that it is difficult to implement D3DRM, just a lot of effort. You can see the missing Create function as a failure like this: "Can't enter the car because there is no door". Now when you try to build a door, you'll see that there's no chassis to attach it to. Once you have the chassis you need engines, seats, etc. Since D3DRM games are rather rare, and the native version is technically useable implementing that is a lot of effort with comparably little gain.
That said, we accept (well written) patches of course :-)
