== About ==
* [http://freesci.linuxgames.com FreeSCI website]
SCI, which Sierra referred to as both the "'''S'''cript '''C'''ode '''I'''nterpreter" and later "'''S'''ierra's '''C'''reative '''I'''nterpreter", is a p-machine style virtual machine for executing platform-independent, object-oriented code.

SCI was designed for 16-bit little-endian computers, although there were later attempts to create 32-bit versions, LSCI and SCI3. SCI was exclusively used by Sierra On-Line, Inc., to run its computer game series, with titles like Leisure Suit Larry 2-7, Space Quest 3-6, King's Quest 4-7, Quest for Glory 1-4, and several others.
 
The SCI engine in ScummVM is based on the code of the FreeSCI project, used with permission.
 
 
== History ==
SCI was initially created in 1988 by Jeff Stephenson to replace [[AGI]]. The first game using it was [[King's Quest IV]] at the same year of its creation, which was simultaneously released with an AGI edition for lower-end machines.

== Debugging ==
* Show priority and control map in original interpreter (SCI1/SCI11)
** search for A9 06 00 74 05 in original interpreter, replace with all 90h (NOP)
* Change days in Gabriel Knight 1
** vmvars g 7bh x - where x is the day number
* Break into debugger immediately on VM start
** Run ScummVM with --debugflags=onstartup
 
== Error loading resource 999.pal message with original interpreter ==
 
=== King's Quest 7 ===
* resource.cfg has to include this:
  directory = .\
  videoDrv  = VESA.DRV
  soundDrv  = ADL.DRV
  audioDrv  = DACBLAST.DRV
  joyDrv    = NO
  cmd      = KQ7DOS
  mouseDrv  = NONE
  memoryDrv = NONE
  minMemory = 1600k
  brightness= 0
  language  = 1
  minCPU    = 386
  CD        = yes
  resMap=.\
  resAUD=.\
  resSFX=.\
  patchDir=.\;.\AVI
  robot=.\
 
* start the game using sierrah -o resource.cfg
 
=== Space Quest 6 ===
* Just start the game using "sierra -o". That will fix it (happens at least with SQ6 DOS included in the Space Quest Collection).
