The beauty of it is, that you don't need a real screen. You can open your
borderless backdrop window in the workbench screen and make it the active
window (use the ACTIVATE flag in the window struct). Then build your 
custom copper list, and display your game. Your A-M/A-N handler need only
pass the rawkey events through to intuition and your program will get them
on it's message port. Windows do not have to be in _front_ to be active.
So the sequence goes something like :

	install_handler();
	win = OpenWindow(borderless backdrop);
	 ...
	MrgCop();
	LoadView(); 
	/* At this point Intuition still thinks your window is "in front and
	active. */
	play_game();
	LoadView(oldview);
	CloseWindow(win);
	remove_handler();


See?

These opinions are my own and no one elses, but you knew that didn't you.
