Since version 1.0.0 ScummVM supports the original cutscenes in smacker format for Broken Sword 1 and the cutscene pack below is not needed. When using older versions of ScummVM you need to get the cutscene pack below (provided with the kind permission of Revolution Software) to replace the original smacker files. It contains video in DXA format and audio in FLAC format. The audio files are also available in OGG format as a separate download to replace FLAC files when using ScummVM on platforms that do not support FLAC audio. Audio files are available in several languages and to use them you just need to replace the English FLAC files from the cutscene pack with the files from your choosen language and format. You may want to get the Subtitles AddOn though as it adds subtitles not present in the original game to the cutscenes.
