Hi there,
            I've been programming the Yaroze for a couple of weeks with
a small amount of sucess but I've come across a problem. I wanted to
recreate that 'fade to battle' effect in FFVII and I know how it's done
but I don't know exactly how to do it. I need to grab the screen and
make it into a transparent sprite an paste the image back onto the
screen again after modifying a bit. Now here's my point, to make a
TIM image transparent, the transparency bits for every pixel in the
image need to be set but when you grab the screen, these bits aren't
set. Arse. All the bits in the screen grab (320*240) need to be set
every frame which slows the frame rate down dramatically. I know it can
be done quicker but how?

        Cheers,
                    Tom.
