In Debian KDE I've set it up so when I mouse into the top left corner it brings up desktop switcher - a 3D 'model' of your desktops that you can drag around and then mouse back into the top left corner to focus in on the desktop in view.
Placing Newport window off a single screen edge and then switching to desktop view mode ... sees the Newport windows 'bent around' both desktop edges
Once you've installed DOSbox which many systems support (Mac, etc.) then the download runs inside that ... i.e. is a form of virtual dos box. No need for other emulators such as XP virtual machine or whatever.
In Linux (Debian) as easy as a "apt-get install dosbox" command. And with a bit of tweaking you can have it as a desktop/menu icon/entry, so no different to opening up any other program. The only odd thing is that it locks the mouse to the window once you've clicked inside the newport window and have to press Ctrl-F10 to release the mouse. There are ways I believe however to add/configure mouse integration (I can't however outline the details here, as I don't know how to do that myself).
