UpdateSurface returns an error

[LegendOfDragoon]

An example of where an error occurs is here https://github.com/death-droid/Rice-Video/blob/master/Device/FrameBufferDX.cpp#L45

I don't think that function works for copying backbuffer. Afaik, that function is meant for transfering system RAM to VRAM. You could probably use LoadSurfacefromSurface or GetREnderTargetData instead.
