King's Quest IV SCI Cover
|Release Date:||September 1988|
|Platform:||MS-DOS, Amiga, Apple IIGS, Atari ST|
King's Quest IV is the first SCI game. To showcase their new SCI engine, Sierra chose its flagship series, King's Quest, to be first to have its next installment to be developed in SCI.
King's Quest IV: The Perils of Rosella featured SCI's higher resolution graphics as well as AdLib and Roland MT-32 music with a "full soundtrack" by William Goldstein. An AGI version of King's Quest IV was co-developed for customers who could not meet the high hardware requirements of Sierra's new SCI engine. A customer who purchased the game that could not run the game was able to send in his SCI disks in for replacement with the AGI version.
Hardware began to advance beyond what AGI could utilize, so Sierra began development on its next engine, SCript Interpreter or later Sierra Creative Interpreter (SCI). A year before the last official AGI game, Manhunter 2: San Francisco in 1989, Sierra released the first SCI (SCI0) game, King's Quest IV: The Perils of Rosella in 1988. In keeping with Moore's Law, SCI could take advantage of the constantly increasing capabilities of the new hardware. As with AGI in its day, SCI was a big leap forward in technology. SCI's 200px x 320px vector graphics allowed for noticeably better graphics over AGI's 160px x 200px. While still just 16 colors, but SCI0 introduced dithering, which mixed pixels of different colors into the same fill areas that gave the effect of more than 16 colors.

SCI introduced support for the new sound cards. This expanded its audio capabilities over that of AGI's three voice with noise channel sound PCjr/Tandy sound. With the advent SCI, music became an inseparable part of Sierra games. Even though the first exposure most had was with AdLib's hoots and honks, it also supported the MPU-401, which allowed Sierra's composers to create some amazing Roland MT-32 sound tracks. KQ4's MT-32 track gave a quality to the game's music that at the time was unsurpassed.

There have been a number of releases of the SCI version of the game, with interpreter versions ranging from 0.000.247 to 0.000.502. In addition to revisions of the PC version, there were ports for other platforms. These ports often had different features based on what the abilities of the target platform. The Amiga port had digital sound effects for environmental sounds, which was missing from the PC version.
Note that the first version(s?) of the game did not recognize resources outside of the resource archive. This made patching the game more difficult as new resource patches cannot simply be dropped into the game's folder. To be accessible to the game the patch needs to be packed and mapped in the game's resource archive to be accessible to the game.

PC version 1.000.106 and 1.000.111 are the only ones with the original detailed graphics. For 1.003.006 and later versions, Sierra simplified the background graphics to make the game fit on one 5.25 inch disk less, removing background detail and separate night pictures.
The KQ4FIX patch dated 1989-02-15 addresses error message "0x80/653 not found" at DOSBox cycle settings above 1500 when entering the screen with the waterfall. This patch only applies to version 1.003.006. This problem was corrected in the later version 1.006.003 and is not needed in versions 1.006.003 or 1.006.004.
PC version 1.006.004 is the latest PC version and has the main character walking faster diagonally. It also changes the arrangement for the Fisherman's theme (for the better) and replaces "Lolotte's death" music with a completely different one. This is the version used for the King's Quest Collector's Edition, King's Quest Collection Series, Roberta Williams Anthology, King's Quest Collection (2006), GOG King's Quest 4+5+6 Collection.
There are two main releases of the SCI version of this game, 1.000.111 and 1.006.004. What is notable is the second release has more refined PICs or background images. Also, the first release used completely new PIC resources for all of the night scenes. The second release used PICs that were night sky overlays that were displayed over the daytime PIC.
