sndbanker is a tool for creating SOUND.DAT files for Bullfrog Productions games. While the original iteration of the tool was for Dungeon Keeper, this particular branch is intended only for Syndicate Wars. Using a properly formatted .txt file and source sound files, the tool can assemble a set of sound samples into a SOUND.DAT file usable by the game.
Place the tool in the root directory of the sound files from the swars-sfx repository.
sndbanker.exe [options] (filename)
e.g. sndbanker.exe -o SOUND.DAT filelist_eng.txt
-o or --output [filename] - specify the filename to create, otherwise the description line in the .txt file will be used. It's recommended to set -o SOUND.DAT -v or --verbose - verbose output of what the tool is doing at each stage
