Ideally, it should just be a matter of getting the screen memory
address and "flipping" the chunk of memory. I've wanted to do this
as well for a game but I've shied away thus far... And of course, very
few things with computers are ever ideal.
It doesn't seem like there's a way to get the screen base address
without accessing Dragonball registers (bad bad) or OS globals (bad
bad). If I had to take my pick though, I'd go with the ScrGlobalsPtr.
(David and Bob: I hope you skipped this paragraph. ;) If you can get
the sources you can at least do it the same way the OS does, for now.
Of course, without trying I'm just shooting off my mouth (I don't
mean in the "gun" sense ;). Flipping the screen sounds easy enough but
in reality there are a _lot_ of dicey issues to deal with. (I'm hoping
if I put this disclaimer in here I won't get the "Stop playing with our
system globals!" speech from David or Bob. <g>)
