NAME
GemRB - a reimplementation of the Infinity Engine
SYNOPSIS
gemrb [-q] [-c CONFIG-FILE]
gemrb PATH-TO-GAME
torment
DESCRIPTION
GemRB a portable open-source implementation of Bioware’s Infinity Engine, which runs fine RPGs like
Baldur's Gate, Icewind Dale and Planescape: Torment.
GemRB reimplements only the game engine. To actually play anything, you have to have the data from the
original game(s), installed or unpackaged where GemRB can find it. See the GamePath and CDn settings in
the engine configuration file below. A full install is recommended.
OPTIONS
-q Disable audio completely, regardless of supported audio plugins.
-f Start in full screen. Try this if the game window suffers from bad aspect ratio. Otherwise just
switch to your preference in the game's video options.
-c FILE
Use the specified configuration file FILE instead of the default gemrb.cfg.
--colorOPTION
Set the ANSI color option for terminal logging. -1 (the default) will attempt to automatically set
this according to the terminal environment. 0 will disable color output, 1 will set it to the
basic 8 color palette, and 2 will use full 24bit color codes.
Note: You can also use the program's name as a mean to select the configuration file. For
example, if the program's name is torment instead of gemrb, the engine first searches for
torment.cfg and only if it's not found it searches for gemrb.cfg.
To use this feature, just create a symbolic link torment pointing to the gemrb binary and then run
torment instead.
CONFIGURATION
A configuration file consists of pairs PARAMETER=VALUE, each on its own line. The case of PARAMETER is
not significant, GameType is the same as GAMETYPE. If the same PARAMETER is defined more than once, only
the last occurrence is used.
Empty lines and lines starting with `#' (hash sign) are ignored.
At least the GamePath parameter needs to be changed. That is often enough, so do not fiddle with the
other paths too much.
General Parameters:
GameType=(auto|bg1|bg2|iwd|iwd2|how|pst)
Type of the game. The value is a name of subdirectory in override/ and GUIScripts/ directories
with game type-specific files and scripts. It is at present also used for various tweaks hardcoded
in the GemRB engine. To autodetect the game type, use the default "auto".
GameName=STRING
Arbitrary name of the game. It will be displayed in the window's title bar.
Encoding=(default|japanese|korean|chinese)
Specify language used in the game data.
GUIEnhancements=INT
The value is a bitfield. Set it to 1 to enable a few GUI enhancements, mostly in BG2. Add or set
to 2 to try to autoidentify items on transfer (if the character has enough lore). Add or set 4 if
you want to skip the item description window when opening bags. Add or set 16 if you want scrolls
for spells the pc does not know yet highlighted. Enabled by default. Add or set 8 if you want the
game to stop mouse scrolling the area at its edges when the window loses focus.
MultipleQuickSaves=(0|1)
EXPERIMENTAL. Set this to 1 if you want GemRB to keep multiple quicksaves around. Disabled by
default.
MaxPartySize=INT
Set this to 1-10 if you want more party members or enforce fewer. 6 by default. NOTE: For bigger
parties you need to choose a big enough resolution, so there will be enough room for all the party
portraits! No space for that in PST or IWD2. The 10pp mod is required to fix various game scripts,
so the extra party members don't get stuck in cutscenes.
Logging=(0|1)
By default (set to 1) logging is enabled and several loggers are used depending on the plaftorm.
Use 0 to disable all logging, which can help in performance critical settings.
Video Parameters:
Width=INT
Game window width (in pixels). This can be arbitrary, but results depend on the game data. Check
the website for a detailed explanation of resolution modes.
Height=INT
Game window height (in pixels).
Bpp=INT
Color depth of the game window (in bits per pixel).
ScaleQuality=(best|linear|nearest)
Use the specified quality for the texture scaling filter. The default is best.
CapFPS=(-1|0|n)
Set FPS handling:
-1: no limit
0: VSync (SDL2), 30 (SDL1)
n: cap to n FPS
SkipIntroVideos=(0|1)
If set to 1, the intro and logo videos are skipped to save developer's nerves. The default is 0.
GCDebug=(0|2047)
Bitfield with reserved bits for drawing Map debug layers.
No Debugging features = 0 (default)
DEBUG_SHOW_INFOPOINTS = 1
DEBUG_SHOW_CONTAINERS = 2
DEBUG_SHOW_DOORS = 4
DEBUG_SHOW_DOORS_SECRET = 8
DEBUG_SHOW_DOORS_DISABLED = 16
DEBUG_SHOW_DOORS_ALL = 28
DEBUG_SHOW_LIGHTMAP = 32
DEBUG_SHOW_WALLS = 64
DEBUG_SHOW_WALLS_ANIM_COVER = 128
DEBUG_SHOW_WALLS_ALL = 192
DEBUG_SHOW_SEARCHMAP = 256
DEBUG_SHOW_FOG_UNEXPLORED = 512
DEBUG_SHOW_FOG_INVISIBLE = 1024
DEBUG_SHOW_FOG_ALL = 1536
Audio Parameters:
AudioDriver=(openal|sdlaudio|none)
Use the specified plugin as the audio driver. The default is openal, while none will disable all
audio.
Path parameters:
CaseSensitive=(0|1)
When this parameter is set to 1, the engine will try to find files regardless of their names' case
at the cost of a slight speed penalty. This is especially important when using game files on CD-
ROMs, where the files can't be renamed. Like many Windows programs, the original games use
inconsistent mix of lower/upper case letters for naming and referencing their files.
Set this parameter to 1 on Unix-like systems.
GamePath=PATH
Path to the directory where the original game is installed. If you can't install the game under MS
Windows or with WINE, you can try to unpack the data files with the unshield program found at
http://synce.sourceforge.net.
CD1=PATH
CD2=PATH
CDn=...
Path to the data files for the game's particular CDs or any other data sources.
CachePath=PATH
User-writable directory where the engine caches uncompressed and temporary files. Defaults to a
subdirectory of the current directory.
GemRBPath=PATH
Path to the GemRB installation. (To be obsoleted; preset at build time).
GUIScriptsPath=PATH
Path to the directory with scripts controlling the game's GUI. (To be obsoleted; preset at build
time).
GemRBOverridePath=PATH
Path where GemRB looks for its game override directory. It defaults to GemRBPath. GemRB reuses
some of the unused files from the original or replaces them and this is the where they can be
found. The path is preset at build time. This directory has the highest priority when searching,
so putting files in the game override will not affect them. Use another directory and add it as
ModPath to the GemRB config.
GemRBUnhardcodedPath=PATH
Path where GemRB looks for its unhardcoded engine data. It defaults to GemRBPath. The original
games hardcoded this information in the engine. The path is preset at build time.
The following variables do not need to be altered, unless you are doing something really special!
SavePath=PATH
Path to the directory with save games. Note that this directory has to contain save/ and/or
eventually mpsave/ subdirectories and that only these subdirectories contain the actual saved
games.
SavePath defaults to GamePath.
GameDataPath=PATH
Path to the original game's installed data files, relative to GamePath. Usually it's data.
GameOverridePath=PATH
Path to the original game's override dir, relative to GamePath. Usually it's override. Original
games use this directory to place last-minute patches.
GameCharactersPath=PATH
Path to the original game's installed data files, relative to GamePath. Usually it's characters.
GamePortraitsPath=PATH
Path to the original game's installed data files, relative to GamePath. Usually it's portraits.
GameScriptsPath=PATH
Path to the original game's installed data files, relative to GamePath. Usually it's scripts.
GameSoundsPath=PATH
Path to the original game's installed data files, relative to GamePath. Usually it's sounds.
GameLanguagePath=PATH Path to the original game's installed data files, relative to GamePath. By
default, it is lang/en_US.
GameMoviesPath=PATH
Path to the original game's installed data files, relative to GamePath. Usually it's movies.
ModPath=PATH
Path where GemRB looks for additional engine override files. It is not set by default. This
directory has precedence over GemRBOverridePath.
CustomFontPath=PATH
Path where GemRB looks for additional font files. It is meant to be used with the TTF font plugin
and fonts.2da as a way to specify where to look for system or other external fonts. Check the
online documentation for the details. It is not set by default.
Input Parameters:
DoubleClickDelay=INT
Millisecond threshold for detecting a double click. The default is 250.
RepeatKeyDelay=INT
Millisecond threshold for detecting a repeated key press. The default is 250.
UseSoftKeyboard=(0|1)
Toggles use of software keyboard on devices that support one. It pops up when text input is
required. Disabled by default.
NumFingScroll=(2|3|4)
Number of fingers for multitouch to trigger scrolling. The default is 2.
NumFingKboard=(2|3|4)
Number of fingers for multitouch to open up the software keyboard. The default is 3. The value
should not be equal to NumFingScroll above.

Force disable = 0
Enable = 1
Development parameters:
EnableCheatKeys=(0|1)
This parameter is meant for developers. If set to 1, certain keys allow you to inspect the
internal state of objects, do forbidden things, etc. The keys are listed in the CheatKeys.txt
file. Do NOT use this option unless you want to make your hands dirty :-). The default is 0.
DrawFPS=(0|1)
This parameter is meant for developers. If set to 1, the current FPS (Frames per Second) value is
drawn in the top left window corner. The default is 0.

512 - enable pathfinding debug mode.
The default is 0.
DelayPlugin=FILENAME
Named plugin will be loaded after other (nondelayed) plugins were loaded. FILENAME is a name
without path, but with extension, for example libNullSound.so or libNullSound.dll. You can use
this parameter more than once.

If set to 1, original aspect ratio is preserved while game area is scaled to native PS Vita
resolution. It is enabled by default.
UseAsLibrary=INT
If set to non-zero, disables some engine features to facilitate independent use of GemRB
libraries. The default is 0.
