GEMRB(6) Games Manual GEMRB(6)

NAME

GemRB - emulator for Infinity Engine-based games
 

SYNOPSIS

gemrb [-c CONFIG-FILE]
 
torment
 
 

DESCRIPTION

GemRB is an emulator for Infinity Engine-based games, 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

-c FILE
Use the specified configuration file FILE instead of the default gemrb.cfg.
 
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 GameType and GamePath parameters need 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 "auto".
 
GameName=STRING
Arbitrary name of the game. It will be displayed in the window's title bar.
 
Encoding=(default|polish|czech)
Specify language used in the game data. Except of polish version of BG1, it's safe to leave it commented out.
 
GUIEnhancements=INT
The value is a bitfield. Setit to 1 to enable a few GUI enhancements, mostly in BG2. Set to 2 or 3 to try to autoidentify items on transfer (if the character has enough lore). Disabled by default.
 
EndianSwitch=(0|1)
Set this to 1 if you are running GemRB on a big-endian machine. Disabled by default.
 
MultipleQuickSaves=(0|1)
EXPERIMENTAL. Set this to 1 if you want GemRB to keep multiple quicksaves around. Disabled by default.
 
MaxPartySize=INT
EXPERIMENTAL: Set this to 1-10 if you want more party members or enforce fewer. 6 by default. NOTE: You need to choose a big enough resolution, so there will be enough room for all the party portraits! Does nothing for PST and IWD2.
 

Video Parameters:

Width=INT
Game window width (in pixels).
 
WARNING: This is not arbitrary but depends on the game data. For custom resolutions the widescreen mod needs to be used.
 
Height=INT
Game window height (in pixels).
 
WARNING: This is not arbitrary but depends on the game data. For custom resolutions the widescreen mod needs to be used.
 
Bpp=INT
Color depth of the game window (in bits per pixel).
 
Fullscreen=(0|1)
Whether the game should run in fullscreen mode.
 
TooltipDelay=INT
Delay (in milliseconds) before tooltips are displayed when the mouse is not moving. A reasonable number for this option is e.g. 500. The default is 100.
 
SkipIntroVideos=(0|1)
If set to 1, the intro and logo videos are skipped to save developer's nerves. The default is 0.
 
FogOfWar=(0|1)
If set to 1, the unexplored parts of an area are blacked out. It is enabled by default.
 
 

Audio Parameters:

AudioDriver=(openal|sdlaudio|none)
Use the specified plugin as the audio driver. The default is openal, while none will disable all audio.
 
VolumeAmbients=INT
Volume of ambient sounds in percents. The default is 100.
 
VolumeMovie=INT
Volume during movie playback in percents. The default is 100.
 
VolumeMusic=INT
Volume of background music in percents. The default is 100.
 
VolumeSFX=INT
Volume of sound effects in percents. The default is 100.
 
VolumeVoices=INT
Volume of PC or NPC voices in percents. The default is 100.
 

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.
 
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.

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.
 
NumFingInfo=(2|3|4)

Hide mouse+tooltips = 3
 

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.
 
ScriptDebugMode=(n)

SkipPlugin=FILENAME
Named plugin will not be 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.
 
SaveAsOriginal=(0|1)
Set this parameter to 1, if you want to keep the save game compatible with the original engine. It is enabled by default.
 
KeepCache=(0|1)
Set this parameter to 1, if you want to keep the cache after exiting GemRB. It is disabled by default.
 
IgnoreOriginalINI=(0|1)

BUGS

Many. GemRB is still in an early development stage and not nearly complete.
 
If you stumble over something which is supposed to work, either make a bug report at http://sourceforge.net/projects/gemrb or come to the official IRC channel #GemRB at FreeNode.
