	On the level of programming, Phantasmagoria 2 was tough as Sierra's SCI engine was being rewritten from almost scratch by the system developers in Oakhurst while the programmers in Bellevue were programming the game.

Every few weeks the programmers would get an update from the system developers which sometimes required changes in the coding. The reason why SCI was being rewritten was because it did not support the DUK movie player.

	When playing Phantasmagoria 2 under Windows, the ~~Duck~~ movies feature 16-bit colors, even though SCI only supports 8-bit colors. What basically happens is that, during the interactive parts, SCI is running. This is why the interactive parts are in 8-bit color, both under DOS and Windows. However the moment the player activates a ~~Duck~~ movie scene, SCI gets essentially shut down and the ~~Duck~~ video player is placed on the game screen. The only action the player can do, is to click the mouse and skip the scene, reactivating the SCI engine. Sierra was considering rewriting SCI in order to support 16-bit colors, but it would have taken too long. Also, while it is possible to play Puzzle of Flesh under DOS, the ~~Duck~~ movies were not meant to play under 8-bit DOS. The programmers got around that by applying CLU files, or Color Look Up files. These are palette files for 8-bit playback. Each ~~Duck~~ file has an equally numbered CLU-file, converting the ~~Duck~~ movie to 8-bit colors.
