Hi guys - this is not a work question, it's a helping a friend out on a Sunday afternoon question that's driving me nuts. Can anyone point me in the direction of a PLAIN ENGLISH site which describes how to get Doom II working under Windows XP and more precisely how to get Game-Tek D-1000 extra levels working with it. I repeatedly see people saying that the "error 200" I am geting is because the computer is too fast - but no-one seems to provide an idiots, step-by-step guide to making it work!! Any suggestions welcomed. Cheers Ed.
