Not applying this leak to TH03 since it would have more than one
`key_det` variable, resulting in names that are as much fanfiction as
the current ones…
Oh, right, these functions can have parameters. So, let's turn snd_kaja_func()
into a macro that combines the function number and the parameter into the AX
value for the driver.
Only one code segment left in both OP and FUUIN! its-happening.gif
Yeah, that commit is way larger than I'm comfortable with, but none of these
functions is particularly large or difficult to decompile (with the exception
of graph_putsa_fx(), which I actually did weeks ago), and OP and MAIN have
their own unique functions in between the shared ones, so…
Oh, OK, so this is what the PC-98 GRCG is all about. 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.
Yes, all of it. Including the bouncing polygons, of course. And since it's
placed at the end of ZUN's code inside the executable, the code's already
position-independent and fully hackable.
