Paste this into your code
Code:
#define FFADE_IN 0x0000 // Just here so we don't pass 0 into the function
#define FFADE_OUT 0x0001 // Fade out (not in)
#define FFADE_MODULATE 0x0002 // Modulate (don't blend)
#define FFADE_STAYOUT 0x0004 // ignores the duration, stays faded out until new ScreenFade message received
and then you can use this flags.
For example:
write_short(FFADE_STAYOUT);
