Fade_out won't work in true colour modes: the reason being that fade_out
shifts the palette values down to black, while true colour modes don't have
a palette.

You could write your own routines using a blender map. Make sure the screen
you want to fade is in a BITMAP, then set the drawing mode to transparant
and set the alpha value you want for transparancy, then blit black
rectangles over the entire screen, until it's completely faded out.
