What I don't understand is that no place in wine seems to return DDERR_UNSUPPORTEDMODE [1], it is only seen in some tests. I can't identify the function returning the error to check if some simple hacking could be done.
It might be generated by the application itself or some library, e.g. because it doesn't like the modes returned by ddraw7_EnumDisplayModes().
