What about rapid page flipping, is it displayed correctly as well?
I recall running Prince of Persia on a Mac LC //e and while sound
and video modes were beautifully emulated, Prince of Persia would
toggle between a red-filled lores screen and hires when our "Prince"
took damage, e.g. falling too far or getting struck by a panel 
or enemy's sword.  The Mac LC //e crept slowly when toggling between
these modes.  Is the SS under the same restrictions?

Thanks!
