There is a section in the Sierra Gamers forums
for those looking for help on getting old Sierra games working on modern machines but, as with the music of Sierra On-Line, there is an off-site expert that will do a far better job. Sierra is gone but the Sierra Technical Support Department is still alive and well at The Sierra Help Pages
. Collector has created and written a variety of custom code, scripts and utilities to help get and keep those old Sierra games running and his site should be your first stop shop when you want to replay Leisure Suit Larry 4. It certainly is ours.
