For graphics card users, such a thing is indeed possible, as long as you
can keep linked on some kind of timer interrupt. As has been said, many
games won't let you do that, unfortunately (but see below).
Without a graphics card, none of this is possible, since the games are
likely to access the video hardware directly.

An emulator would be too slow on most (if not all) Atari compatible hardware,
but it _might_ be possible to implement some kind of virtual machine on
>='030 processors. I doubt anyone will ever attempt that, though.
The simplest possible 'virtual machine' would be one that only relocates
the exception tables (I doubt any games worries about such things) and then
does some kind of software interrupt dispatch from the new vector addresses.
It could then be possible to add some kind of timer-driven screen copying
that the game wouldn't know about.

We _really_ should port that program!
