I just stumbled upon this little project.
Jerzy Grzechnik is doing a version of King's Quest IV running on Myles' altered ScummVM capable of using custom backgrounds, sound etc. with the original Sierra games.
Jerry is using backgrounds from several different King's Quest IV remake projects and has also added voice acting. Seems pretty interesting.
