NAME

       freesci - free interpreter for SCI bytecode

DESCRIPTION

       FreeSCI  is  a  portable interpreter for SCI games, such as the Space Quest series (starting with SQ3) or
       Leisure Suit Larry (2 and sequels); see below for a complete listing.

       freesci is the main executable which loads, links and runs SCI bytecode.

SYNOPSIS

       freesci [options] [game [savegame]]

OPTIONS

       game   An identifier describing the game to start. This identifier (GAME_ID)  must  be  declared  in  the
              configuration  file.  If  omitted,  the  interpreter  will attempt to read resource files from the
              current working directory (or the directory specified by the --gamedir option). If that fails,  it
              will  present  a  graphical  game selection screen for the games listed in the config file and the
              games located under ~/.freesci/games (or the directory specified by the --menudir option).

       savegame
              If this option is specified after the game name, the interpreter will  attempt  to  quickload  the
              savegame  with  the  specified ID (see the --list-savegames option). This is technically different
              from restoring a savegame from within the game (as it does not  re-start  the  game  script  state
              afterwards), but it should work just as well.

       --version, -v
              Display  version  number  and  exit.  Also the supported graphics drivers, sound servers, midi and
              midiout drivers are reported.

       --help, -h
              Display a short help text and exit.

       --run, -r
              Do not start the debugger; only run the game. This is the default action.

       --debug, -D
              Start up in debug mode.

       --list-savegames, -l
              This option instructs the interpreter not to run the game, but rather to list all savegames stored
              for  it,  including  their  in-game  descriptions where available.  This is relevant to figure out
              savegame names for  quickloads.   The  usual  in-game  savegames  are  labelled  “save_0”  through
              “save_j”.

       --gamedir dir, -ddir
              With  this  option,  games  resources  will be read from the directory dir. Default is the current
              directory, unless a directory has been specified in the config file (see below).

       --menudir dir, -Gdir
              This option sets the directory that the graphical game selection menu recurses  to  look  for  SCI
              games.  Default  is  ~/.freesci/games,  unless  the menu_dir option is set in the config file (see
              below).

       --sci-version version, -Vversion
              This option sets the SCI version for freesci to emulate.  Acceptable version numbers  are  of  the
              form x.yyy.zzz, where x is the major number, yyy is the minor number and zzz the patch level.

              Note that currectly only SCI0 and SCI01 (major/minor=0/000) games are supported.

              Normally, the version will be autodetected from the game resource files.

       --disable-mouse, -m
              Many  SCI  games  handle  the mouse pointer differently if no mouse is present in the system. This
              option instructs the interpreter to tell the games that no mouse is present whenever they ask  for
              one; the actual effect depends on the individual game.

       --scale-x xfact, -xxfact
              --scale-y  yfact,  -yyfact  These  options allow to explicitly specify the horizontal and vertical
              scaling factors. The resulting size of the game window will be 320*xfact  x  200*yfact,  plus  any
              window decorations.

       --color-depth bpp, -cbpp
              This sets the number of bits to use per pixel. Some visuals/graphics drivers support several color
              depths, so that auto-detection may not yield the desired effects.

       --graphics gfx, -ggfx
              With this option, you can specify which graphics driver is to be used.

              In this release, sdl, ggi and plain xlib are supported.

       --midiout driver, -Odriver
              This is the output driver or interface to use. Currently, unixraw,  alsaraw,  null,  ossopl3,  and
              ossseq (an OSS sequencer driver) may be available on your system, ossseq being the default.

       --mididevice driver, -Mdriver
              SCI  was  designed to support a variety of physical output devices. FreeSCI currently supports the
              Rolant MT-32 (mt32, the default), an Adlib device (adlib) and it also offers an MT-32  to  General
              MIDI translation layer (mt32gm).

       --sound-server server, -Sserver
              This  option  may  be  used  to  explicitly specify a sound server to use.  The sound server is an
              asynchronous process or thread that issues sound output events and reports sound cues back to  the
              interpreter;  if  you  have  both  possibilities  (unix  and sdl) for your system, you may have to
              experiment to find out which works best for you.

CONFIG FILE

       When run, FreeSCI will create a directory called .freesci in your home directory (unless  this  directory
       already  exists).  If  you  run  an SCI game, this game will create another directory inside the .freesci
       directory, to store its save games in.

       Also, if a file called config exists in this directory, it will be read and  parsed  by  the  interpreter
       after  the game has been loaded. This configuration file can be divided into a global section and various
       game-specific sections.  Within the config file, comments must be preceeded by a hash  “#”  sign.   Empty
       lines are ignored.

       Game-specific  sections are marked by a text string like [GAME_ID], where GAME_ID is an ID to use for the
       game. If the section also contains a resource_dir entry, the ID may be passed to freesci as  a  parameter
       to start the game by its name.

       The  config  file  section  before  the  first game-specific section is the global configuration section;
       anything specified here will be used as the setting  for  any  game  that  does  not  explicitly  request
       different settings.

       It  is  possible to include other files with the %include<#> directive. FreeSCI will automatically detect
       and warn about circular inclusions.

       Here is a complete listing of all options supported:

       GENERAL OPTIONS:

       resource_dir
              Read the game's resource data from the specified location. Must not be used in the generic part of
              the config file.

       menu_dir = dir
              Specifies  the directory that is recursively searched for SCI games when the game selection screen
              is  invoked.  Should  only  be  used  in  the  generic  part  of  the  config  file.  Defaults  to
              ~/.freesci/games.

       version = x.yyy.zzz
              Emulate  SCI  version  x.yyy.zzz. The version number is sometimes printed on game discs, or can be
              found out by grepping your main executable for "0.000." (for SCI0 games). It is also displayed  if
              the  built-in  debugger  is activated in the Sierra SCI engine. See also the --sci-version command
              line option.

       console_log
              Sets a logging file for FreeSCI's console output (by default, this is disabled).

       mouse = yes | no
              Specifies whether the interpreter should report to the game that it has a mouse.

       GRAPHICS OPTIONS:

       pic0_dither_mode = dither | flat | dither256
              dither: draw in 16 colors, same as  Sierra  SCI;  flat:  interpolate  colors  (256  colors);  this
              improves some graphics; dither256: dither in 256 colors; a compromise between dither and flat.

       pic0_dither_pattern = scaled | unscaled
              scaled:  perform  picture  dithering  to blocks with a width of the horizontal and a height of the
              vertical scaling factor; unscaled: dither single pixels (same as scaled if the game is  being  run
              unscaled).

       pic0_brush_mode = scaled | ellipses | random-ellipses | more-random
              Affects  how  semi-random  brushes (used mostly for dirt and foilage) are drawn in SCI0 background
              pictures. scaled: scale every semi-random pixel to a  rectangular  block;  ellipses:  scale  every
              semi-random  pixel  to  a filled ellipse; random-ellipses: as ellipses, but slightly shift ellipse
              offset and size; more-random: add more random pixels to the whole area.

       pic0_line_mode = correct | fine | half
              Specify how lines are drawn when background pictures are rendered in SCI0.   correct:  draw  lines
              appropriately  scaled;  fine: don't scale lines (thin lines, may cause problems); half: draw lines
              at half width (may cause problems).

       dirty_strategy = 1 | clusters
              The “dirty strategy” is the  strategy  used  to  collect  modifications  to  the  screen  content.
              Modifying  this may affect performance on slow or networked systems.  1: collect everything in one
              dirty region; clusters: cluster non-overlapping modified regions into a set of regions.

       pic0_scaled = yes | no
              Whether SCI0 background pics should be scaled (may look better) or not (faster,  looks  more  like
              the original games). By default, it is disabled.

       pic_buffer_size = #
              Number  of  background  pics  to  store  in an LRU buffer. Increasing this value will increase the
              amount of memory used, but may considerably speed up changing back to rooms you  visited  not  too
              long ago.

       view_filter = none | linear | trilinear
              Specifies  the  way  views  (non-background  images)  are  scaled  (this obviously does not affect
              unscaled images): none: no filtering is performed (default); linear: a  simple  linear  filter  is
              applied; trilinear: views are passed through a trilinear filter.

       pic_filter = none | linear | trilinear
              Specifies scaling for background images; see view_filter for a description of the options.

       cursor_filter = none | linear | trilinear
              Specifies  scaling  for  mouse  pointers;  see view_filter for a description of the options.  This
              option does not apply to graphics drivers which handle the mouse  pointer  explicitly  (currently,
              only the GGI driver is affected).

       text_filter = none | linear | trilinear
              Specifies scaling for text; see view_filter for a description of the options.

       pic_antialiasing = none | simple
              If  activated,  this  option  will  do  an  extra pass over background images to anti-aliase them,
              usually improving the overall picture quality. This is set to none by default.

       animation_delay = #
              This chooses the amount of microseconds to wait between each sub-element of a transition animation
              (also  see  animation_granularity).  Setting  this  to  zero  will  disable  transition animations
              completely.  The default is 5.

       animation_granularity = #
              This sets the amount of  steps  to  execute  simultaneously  for  each  transition  animation.  If
              transition  animations seem too slow on your system but you don't want to disable them completely,
              you might want to try increasing this value.  The default is 4.

       alpha_threshold = #
              When using filtered images (specifically views, text, and  cursors  where  used  by  the  graphics
              driver),  this  value  is  used  to determine when a part of the image should be drawn and when it
              should be omitted. The definition space of this value is 0 to 255, where larger values cause  more
              to  be  drawn.   This value does not affect unfiltered images or images drawn with alpha blending.
              Default is 129.

       SOUND OPTIONS:

       midi_device = driver
              Chooses the default MIDI device; this can be mt32  for  plain  MT-32  output,  or  mt32gm  to  use
              FreeSCI's  MT32 -> General MIDI mapping algorithm. Also Adlib (adlib) is supported.  This defaults
              to mt32gm.

       midiout_driver = driver
              Selects the output device to use. Available options are alsaraw  (using  ALSA's  raw  MIDI  output
              devices),  unixraw  (using  /dev/midi-style  raw  MIDI  output devices), ossseq (for OSS sequencer
              devices) and win32mci on Win32 systems.  The default on UNIXish systems is ossseq.

       sound_server = server
              This chooses one of the asynchronous sound servers. For sound output, FreeSCI uses an asynchronous
              process  or  thread;  currently  two  implementations of this mechanism are available: unix, which
              forks off a separate process, and sdl, which uses  libsdl's  threading  mechanisms.   Defaults  to
              unix, where available.

       DRIVER-SPECIFIC OPTIONS (GRAPHICS DRIVERS):

       gfx.xlib.disable_shmem = yes | no
              Can  be  used  to  disable  support for MIT Shm support on the X11 Windowing System in cases where
              detection fails.  This is off by default, enabling SHM support.

       gfx.sdl.swap_caps_ctrl = yes | no
              This option instructs the SDL driver to swap caps lock and ctrl when reading input.   Disabled  by
              default.

       gfx.sdl.fullscreen = yes | no
              Toggles the SDL graphics driver's fullscreen option. Disabled by default.

       DRIVER-SPECIFIC OPTIONS (SOUND DRIVERS):

       midiout.alsaraw.card = #
              This specifies the ALSA card to use for raw MIDI output; the default is 0.

       midiout.alsaraw.device = #
              Specifies the ALSA device, relative to the card, for raw MIDI output. It also defaults to 0.

       midiout.unixraw.device = device
              Sets the device file to use for raw UNIX MIDI output.  This defaults to /dev/midi.

       midiout.ossseq.device = #
              Selects the OSS sequencer device number; this defaults to 1.

       midiout.ossseq.recorder = file
              Chooses  a  file  the OSS sequencer should print debug output to. This is not particularly helpful
              for everyday use, and disabled by default.

       PER-RESOURCE COLOUR CUSTOMISATION:

       FreeSCI allows the brightness and hue of in-game images to be customised. A complete description of  this
       mechanism can be found in the accompanying README.

SUPPORTED GAMES

       The  following  games have been tested with FreeSCI and are known to give some level of interactivity. In
       theory, FreeSCI should be able to let you complete  all  of  these.  Games  marked  with  [c]  have  been
       completed using FreeSCI.

       •      Hero's Quest / Quest for Glory 1 [c]
       •      Space Quest 3 [c]
       •      King's Quest 1 (SCI version) [c]
       •      King's Quest 4 [c]

       •      Hoyle's Book of Games (volume 1) (*)
       •      Hoyle's Book of Games (volume 2) (*)
       (*)  Due  to differences between the way Sierra SCI and FreeSCI handle graphical widgets, these games may
       cause an accumulation of widgets in the widget subsystem, resulting in  a  slowdown  and  some  increased
       memory usage.

BUGS

       This release has the following limitations (plus some bugs):
       •      Only SCI0 games (and some SCI01 games) are supported
       •      The SCI debug functions aren't fully supported (and probably never will be, since FreeSCI uses its
              own debug functions).

       Please refer to http://freesci.linuxgames.com's bug list section for a listing of all known  and  current
       bugs.
