That's something else I think.
O well just try setting it to whatever it's currently not. Try updating the drivers for your graphics card (for that you need to know what it is though), update DirectX and download Visual C++ Runtimes from Microsofts website.
Otherwise you will just have to try a different emu, although they all struggle to run this game well. NeonDS also does not have sound at this stage by the way.
