hi Tony,
could it be possible to display the upper part on a 1st monitor and the bottom part on the 2nd ???
Fullwindow by exemple could use the 2 screen when the 2nd screen is in extended mode ???
The goal you will ask ??? play lotus or others game with a splitscreen option :
player 1 upper screen-> screen 1
player 2 bottom screen -> screen 2
like this the 2 players can play virtualy like in fullscreen.
I did it with resident evil 6 and i had no problem; with winuae the problem is that you can't stretch the window between two screen (extended mode),
This 1 screen or the other one.
I hope i was clear enough.
