Hi,
Found this link for it.
http://dosbox.sourceforge.net/news.php?show_news=1
Seems it needs to be played through an Emu called Dosbox, which can be download from the site and may work with XP,
Not sure if the game can be downloaded from the site though, Getting the game looks like the hard part, I'll keep digging around on the net though.
Have a read on the Dosbox site,
