You call grcg_setcolor(), and that puts the PC-98 hardware in some sort of "monochromatic mode". Then, you just write your pixels into any single one of the 4 VRAM bitplanes. This causes the hardware to automatically write to all bitplanes in such a way that the final palette index for each of the 8, 16, or 32 pixels you just wrote a 1 value to will actually end up to match the color you set earlier. Don't forget to call grcg_off() at the end though, or you can't draw any non-monochromatic graphics, heh.	2015-02-25 23:05:20 +01:00

you just write your pixels into any *single* one of the 4 VRAM bitplanes. This
causes the hardware to automatically write to *all* bitplanes in such a way
that the final palette index for each of the 8, 16, or 32 pixels you just wrote
a 1 value to will actually end up to match the color you set earlier.

non-monochromatic graphics, heh.
