They are Dos Games but if you dont want to run it on XP, download DosBox from Utilities, Programs (left side of the screen on the main page etc).
Make sure you put your game some where easily, with short folder names...
eg. c:\dosgames\KQ1\
Then run dos box, type:
1) mount c c:\dosgames\KQ1\
2) c:
3) type executable here
I installed the speak pack to the same directory and got the error shown below when I knocked on the lolly house door. Is this because it can only be run in dosbox?
