[A83] Re: Inverting on home screen




I still do not quite understand how it works, especially since it does not
work in my program.  Perhaps I ought to be more specific:
I'm trying to make a menu where by going up/down, your selection gets
highlighted.  So, now I need to invert 32 spaces or 16, but I can figure
that out myself.  I looked in the SDK, but I still do not understand exactly
how textshadow works.
-Is it updated right away?
-Is it cleared when "fastcopy" is called?
-How can I change something in it at a certain point?
