When these programs were moved to faster hardware, they became unplayable. Someone wrote a TSR (dos only of course) that would lock on to the timer interrupt, and every time it fired, the TSR would insert a big loop to burn cpu cycles. You could adjust this loop to make a 386/25 run like an 8086 if your graphical program was running too fast to play. That is the simplest way I know of, but have no idea how to do it under windows, or if it can even be done...
