King's Quest IV: The Perils of Rosella AGI was co-developed with the King's Quest IV SCI for customers who could not meet the high hardware requirements of Sierra's new SCI engine. Citation RQD 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.
