I am running WC4, DOS version in DosBox on a WIN7-64 bit PC. I had trouble installing this game in DoxBox but reloaded DosBox 0.74 and was able to install and run. However, the sound was choppy and I found that the video was also choppy when I went to the game movie itself. The solution for me was to enter the DosBox config file and set the following parameters under [cpu]: Core = Normal Cycles = auto (This made the biggest change. For some games it needs a value, like 13908. This is the value I use for Tex Murphy games.) Cycleup = 1500 Cycledown = 20 The above settings reduced the choppy sound and video to almost nothing.
