Well, the Mac's display is 512x384 for the 9" screen, not 525 vertical lines,
so there shouldn't be a problem there. Additionally, Dark Castle *does*
work in a window.  The window is the exact size of the 9" screen, but if
you run Dark Castle on a larger monitor (say the 640x480 Mac II screen),
the playing field will be in a window, centered on the screen. It's safe
to say that programs that hog the whole screen are considered "non-well-
behaved" as far as the Mac is concerned.

What is the level of emulation?  Mac+/SE a la AMAX/Stacy, or MacII/SE30
with Color QD support and stuff like that?  How extensive will be the
support for new features (like Virtual Memory in System 7, or 32-bit
QuickDraw, for example)?

I really think that this product does have a lot of potential, and I'd
really like to see it succeed.  The technical hurdles are significant,
however, and the compatibility problems are bound to be hairy in
certain areas (I'd hate to be working on the Sound Manager, for example),
especially in the areas where there are features of the Mac OS which
do not readily translate to GSOS (Notification Manager?).  I guess I sound
fairly skeptical, but I'd love to see it happen.  We'll see.
