This WeiDU mod allows you to biff the content of the override folder for improved performance, that means the files are converted into the BIF file format and moved into the data folder. This works natively under OSX and Linux (if you use the correct executable) and is compatible with the common WeiDU stack un-install operation. The game thereby loads much faster again and the performance is running pretty smoothly without jerking.

Note: Recent user reports have indicated that Generalized Biffing is unnecessary for Enhanced Edition games.

Generalized Biffing > OverviewBACK TO TOP


Games supported

Generalized Biffing is designed to work on all Infinity Engine games.

Other Mods Compatibility

This mod is a WeiDU mod, and therefore should be compatible with all WeiDU mods. It must be installed after all other mods. If you encounter any bugs, please report them on the forum!

Installation Order

➽ Please install Generalized Biffing after all other mods.

Generalized Biffing > CompatibilityBACK TO TOP



If you've previously installed the mod, remove it before extracting the new version. To do this, run  setup-generalized_biffing.exe , un-install all previously installed components and delete the 📁 generalized_biffing folder.

When installing or un-installing, do not close the DOS window by clicking on the X button! Instead, press the Enter key whenever instructed to do so.

Disable any antivirus or other memory-resident software before installing this or any other mod. Some (particularly avast and Norton!) have a tendency to report false positives with mod activity, resulting in failed installs.

You can extract files from the archive using 7zip, WinRAR, ZipGenius, or another file compression utility that handles .zip files.

Enhanced Editions Note

The Enhanced Editions are actively supported games. Please note that every patch update will wipe your current mod setup! If in the middle of a modded game you might want to delay the patch update (if possible) as even after reinstalling the mods, you might not be able to continue with your old savegames. Alternatively, copy the whole game's folder into a new one that can be modded and will stay untouched by game patches. It is important that you install the mod to the language version you are playing the game in. Otherwise, the dialogues of the mod will not show but give error messages.


Generalized Biffing for Windows is distributed as an extractable compressed archive and includes a WeiDU installer.

Extract the contents of the mod to the folder of the game you wish to modify (the folder which contains the "CHITIN.KEY" file). On successful extraction, there should be a 📁 generalized_biffing folder and a setup-generalized_biffing.exe file in your game folder. To install, simply double-click  setup-generalized_biffing.exe  and follow the instructions on screen.

Run  setup-generalized_biffing.exe  in your game folder to reinstall, un-install or otherwise change components.

Mac OS

Generalized Biffing for Mac OS distributed in the same compressed archive and includes a WeiDU installer.

First, extract the files from the archive into your game directory. On successful extraction, there should be a 📁 generalized_biffing folder, setup-generalized_biffing and setup-generalized_biffing.command files in your game folder. To install, double-click  setup-generalized_biffing.command  and follow the instructions on screen.

You can run  setup-generalized_biffing.command  in your game folder to reinstall, un-install or otherwise the components settings.


Generalized Biffing for Linux is distributed in the same compressed archive and does not include a WeiDU installer.

Extract the contents of the mod to the folder of the game you wish to modify.

Download the latest Linux version of WeiDU and copy weidu, weinstall and tolower to /usr/bin. Then open a terminal and  cd  to your game installation directory.

Optional: run 'tolower' and answer 'Y' to both queries. You can avoid running the second option (linux.ini) if you've already ran it once in the same directory. To save time, the archive is already tolowered, so there's no need to run the first option (lowercasing file names) either, if you've extracted only this mod since the last time you lowercased file names. If unsure, running tolower and choosing both options is the safe bet.

Run  WeInstall setup-generalized_biffing  in your game folder to install the mod. Then run  wine BGMain.exe  (or  wine baldur.exe  for EE games), and start playing.

Note for Complete Un-installation

In addition to the methods above for removing individual components, you can completely un-install the mod using  setup-generalized_biffing --uninstall  at the command line to remove all components without wading through prompts.

Generalized Biffing > InstallationBACK TO TOP


As of v2.3, the installer splits main component into two sub components, letting the player decide if he wants to biff all files or only .wav, .tis and .bam files.

The LABEL of each component gives a fixed component ID, regardles of DESIGNATED changes. Other mods should use labels to detect component installation.

[0] Biff only .wav, .tis and .bam files.

➽ This component might be enough for installations with few mods (recommended by The Bigg and other "Small World Dudes").

[1] Biff all files.

➽ This component is recommended by the "Big World Dudes" (practically essential for installations with many mods).

These are some general tips if you have problems getting the game working, with or without this or other mods. Many times, errors have to do with the game engine itself or the manner of installation or gameplay. The game recommends deleting all files out of the /cache, /temp and /tempsave 📁 sub-folders in your game folder to see if that resolves the problem before any further troubleshooting.

Symptom: Game freezes or crashes to desktop (CTDs)

Sometimes the game displays an "assertion error" in a pop-up window when this happens, but often times it doesn't. To enable the full error message, open the file baldur.ini in your game folder with a text editor (such as Notepad). If you find you can't edit it or save changes in Windows Vista or 7, see this topic for assistance.

Under the [Program Options] section in the file, type Logging On=1 (unless it's already there). While you're there, you may also want to make sure Debug Mode=1 is there to enable the CLUA Console for debugging and testing. Save the file and exit. Now go back into the game and try to reproduce the crash. Then look in your game folder again for the Baldur.err file and open it with a text editor to analyse its contents.

Symptom: Game crashes with no Baldur.err log and shows either a black screen or a pop-up window indicating an error at offset 005ca8a8

This usually indicates an animation-related issue. Make sure you have the latest version of the mod. If you've installed other mods after it and have this issue, install the fix available here.


ERROR: error copying [infinityanimations/content/somefile.bam]
ERROR: [SOMEFILE.CRE] -> [override/SOMEFILE.CRE] Patching failed (COPY)
Stopping installation because of error.
(with no other error message)

Less-than-informative messages like these may indicate you're installing to a hard drive with a low data transfer rate or an antivirus program is active during installation (which can also affect data transfer). Try installing to an internal drive with antivirus protection disabled during the install. If unsure, disconnect from the Internet (either unplug your network cable or disable your wireless adaptor) and turn off all memory-resident programs during the install. To get a list of these, go to Start > Run and type  msconfig  where it says "Open:" then click OK. When the System Configuration Utility appears, click on the Startup tab. The only really necessary programs that need to be loaded in memory at startup are those related to your graphics chip (typically ATI or NVIDIA). Uncheck everything else, reboot and try installing the mod again. There are well-documented issues with installing mods while Avast antivirus is running, so make absolutely sure all components of Avast are completely disabled.

Other issues

If none of this resolves your issue, or you have mod-specific issues, please report the problem in the mod's forum. Include the contents of your WeiDU.log file in the post, or attach it if it's large.
