(re: King’s Quest 5 problem)
I’ve been having the same problem… finally figured it out earlier today. Basically it gets stuck at the Sierra screen because of a sound configuration problem (whether it came up with the hardware initialization error or not). I found that if I installed the game and chose the IBM PS1 option for Audio, then the game would play…. (albeit with no sound!!!). I’m still stuck trying to get the speech to work so I can play it properly.
