 ### Microsoft Windows 3.x and 9x
 
-There are multiple ways to run Windows 3.x and Windows 9x games and ES-DE provides support for two main options. The first approach is to run these games inside a complete operating system emulated via DOSBox and the second approach is to use shortcuts, scripts or AppImages to run the games separately via applications like Wine or Lutris or by using source ports and similar.
+There are multiple ways to run Windows 3.x and Windows 9x games and two different approaches are covered here. The first option is to run these games inside a complete operating system emulated via DOSBox and the second option is to use shortcuts, scripts or AppImages to run the games separately via applications like Wine or Lutris or by using source ports and similar. It may also be possible to run these games as zip files via DOSBox-Pure (which is available as an alternative emulator for these systems), but it's not covered here.
 
 The second approach is very flexible but does not lead to the most authentic experience in many cases. It will also not be covered in detail here. As long as you have a script, shortcut or AppImage that can be launched outside ES-DE you should be able to place it into the `~/ROMs/windows3x` or `~/ROMs/windows9x` directories and launch it inside ES-DE as well (assuming you have selected the correct alternative emulator entry). If you've named the files appropriately it should also be possible to scrape them.
