<p>oh that's cute. their set_palette function takes two arguments: a pointer to the palette, and a number of extra palettes to apply. </p><p>so they could set up an array of palettes in decreasing brightness, and just do set_palette(&fade_pallets[0], 64) to go through them.</p><p>but the same function is a regular one-time set_palette if you just pass 1 for the second argument.</p>
