Does anyone know if Wolf3D is in ModeX, Y, or 13h?

is it possible to tell?

and also, if you are going to bother programming an interrupt for the
vertical retrace, then why bother wasting precious display memory for
switching pages?  Just make your copy routine check to make sure it is
OK to write to the screen before it does, and then more images can be
fit into display memory.

you, of course, would have to dosome pretty fancy footwork to make sure
you never accessed the displayed page except when vertical blanking was
in effect, but I imagine it could be done.
