(re: I need help with Silent Thunder: A-10 Tank Killer)
actually, of the older sierra games, the dos versions sometimes run in XP when the windows versions won’t. (king’s quest 5 & 6 for example.) some games require help from a third party software like DosBox or VDMSound.
i don’t have this game so i can’t help you. try the technical forums at Gameboomers or Adventuregamers or NTCompatible.
