Command-line parameters

Command-line parameters, also called arguments, flags, or switches, are options for the initial execution of software. These options are commonly supplied in a command-line window or shortcut, and always come after the executable's file name. Available parameters, syntax, and effect all depend on the game or software they are used with. A common use for these options is for running games in debug mode or different resolutions.

Example:

"C:\Program Files\OldGame\Game.exe" -firstoption -secondoption

"C:\Program Files\NewGame\Game.exe" /FIRSTOPTION /SECONDOPTION

For further information, see Command-line interface § Arguments on Wikipedia.

Currently, five LEGO video games for Windows are known to have command-line parameters:

LEGO Racers

There are seven command-line parameters in the 1999 version of LEGO Racers, and eight in the 2001 version. Entering an incorrect parameter will cause LEGO Racers to terminate its launch and open an error message box, which displays a list of all parameters and their functions (except for -fov).

Argument	Effect
-alphatrans	Forces use of alpha transparency
-horzres [res]	Sets the value in pixels for horizontal display resolution. Replace [res] with an integer.
-novideo	Disables playback of opening videos
-primary	Forces use of primary display device. This parameter will be ignored if -select3d is also used.
-select3d	Allows display driver and Direct3D device selection before the game launches (may not work with the Japanese version)[verify]
-vertres [res]	Sets the value in pixels for vertical display resolution. Replace [res] with an integer.
-window	Allows the game to be launched in a window when in 16-bit color depth. The window will minimize if focus is lost.
The following parameter only works with the 2001 version
-fov [deg]	Sets the value in degrees for the in-game camera's field of view. Replace [deg] with an integer. 90 is the default value. Values above 180 will invert the field of view. Values of 360 and onward can be used, but will be read as their coterminal equivalent below 360 degrees (e.g. 450=90).

LEGO Racers 2

There are twenty-six command-line parameters in LEGO Racers 2.

Argument	Effect
/backlevel	Untested
/bpp	Untested
/cars	Untested
/device	Untested
/explore	When any track is selected to race on, the player will be taken to explore mode in that track's world instead
/foyer	When any track is selected to race on, the player will be taken to the track's world's foyer instead (except for Sandy Bay, which has no foyer and forces the player into explore mode)
/height [res]	Sets the value in pixels for vertical display resolution. Replace [res] with an integer.
/highqualitysound	Untested
/hz	Untested, may not be in all versions
/levelname	Untested
/loadcontroldata	Untested
/lowqualitysound	Untested
/nomusic	Disables in-game music
/nosfx	Mutes all audio. Attempting to start a new adventure will crash the game.
/options	An options window appears on game start
/overdraw	Makes all polygons translucent, showing how many layers are overlapping
/racers [range]	Changes the number of racers. Replace [range] with an integer between 1 and 8
/script	Untested
/startpos	Changes your starting position
/track	Untested
/width [res]	Sets the value in pixels for horizontal display resolution. Replace [res] with an integer.
/windowed	Allows the game to be launched in a window
/windowx	Untested
/windowy	Untested
/wireframe	Displays all graphics in wireframe mode
/savecontroldata	Untested

LEGO Rock Raiders

There are twenty-four command-line parameters in LEGO Rock Raiders.

Argument	Effect
-best	Launches the game with maximum graphics settings, skipping the Mode Selection prompt
-cleansaves	Deletes all saved games
-debug	Allows for display resolutions of 640x480, 800x600, or 1024x768 to be selected. However, only the positions and dimensions of interface items for a 640x480 resolution are defined in Lego.cfg by default; without extensive edits to designate coordinates for the latter two resolutions, selecting either of those options will cause the game to immediately crash. (Does not enable debug mode)
-debugcomplete	Allows for display resolutions of 640x480, 800x600, or 1024x768 to be selected. However, only the positions and dimensions of interface items for a 640x480 resolution are defined in Lego.cfg by default; without extensive edits to designate coordinates for the latter two resolutions, selecting either of those options will cause the game to immediately crash. (Does not enable debug mode) Seems to have the same effect as -debug. Further research needed.
-dualmouse	Enables seperate detection of left and right mouse button presses.
-flags	Followed with an integer to "turn on certain debug features"[verify]
-fpslock	Enables VSync, which locks the frame rate to the monitor refresh rate when running in a window
-ftm	Forces the video card to use all available texture memory and disables in-game dynamic lighting (except for walls)
-fvf	Creates a gradual fog effect while in eye view or shoulder view
-insistOnCD	Makes the game request the disc before it starts
-nm	Disables texture management for Voodoo2-based cards. Incorrectly listed as -nom in the readme file.
-nosound	Mutes all in-game sound
-programmer	Enables debug keys and allows the opening logos to be skipped
-reduceanimation	Disables the rockfall transition animation in the main menu
-reduceflics	Disables all FLIC animations
-reduceimages	Texture sizes are halved at load time, reducing the memory overhead
-reducepromeshes	Reduces the number of LOD meshes
-reducesamples	Disables sounds on the menu (except for clicking and music), voices (except for Chief's briefings), and cave ambiance. Streamed sounds, such as the aforementioned music and briefings, are unaffected.
-reward	Disables Chief's animation on the reward screen
-showversion	Displays the game's version number (V.0.121) in the bottom-right corner of the main menu, level select, and pause menu
-startlevel	Launches the game directly into a level; may need a level name (e.g. Level10) or an integer as a parameter[verify]
-testercall	Unlocks all levels at start, same as -testlevels
-testlevels	Unlocks all levels at start
-window	Allows the game to be launched in a window when in 16-bit color mode

LEGO Stunt Rally

These parameters must be used in a shortcut to _msr.exe, not StuntRally.exe

• 0.3.5.1 is the version number for the original release of the game.
• 0.3.8.1 is the version number for the later, more common releases of the game, as well as the Japanese demo by Eidos.
