The first time you try running a "standard" DOS game, it will try to
   run in a window on your desktop. Type ALT-ENTER to switch it to a full
   screen.
   
   To fix that setting in place, bring up the program's properties, hit
   the Screen tab, and set the screen usage to Full Screen. There are
   other screen controls here:
   
   "Fast ROM Emulation" works if the video driver emulates its BIOS in
   protected mode. Newest drivers from Cirrus Logic, for example, emulate
   their BIOSes in 32-bit DLLs. Try turning it off if you can't get VESA
   games working, though a properly written Win95 video driver should
   emulate VESA video modes in protected mode.
   
   "Dynamic memory allocation" specifies that Win95 will grab system
   memory as needed to update the game's display. Try turning this off if
   the display jitters, or the hard drive goes crazy as the display
   updates itself.
