Just got Dolphin, some help...?

[Kanan]

I downloaded Dolphin to play this game, Xenoblade.
But it gives me this error;

Failed to load DSP rom ys/GC/dsp_rom.bin
and
Failed to load DSP rom ys/GC/dsp_coef.bin

I also downloaded the DSPspy, but nothing.
Perhaps I haven't set everything well? If there are similar topics, my bad for this.

Thanks.
