  The problem with this code is that you're specifying color 255 but this means
nothing until you tell it which palette you're using.

Insert the line ...

set_palette(desktop_palette);

...after set_gfx_mode and change the color in textout centre to 1 instead of
255, (I know this to be red), compile link and run.
