Hiho,
I'm surprised there doesn't seem to be a tool that can handle these files.
Well, so I made one :)
You can download it from
http://gamefileformats.the-underdogs.info/files/bundleexplorer-1.0.zip)
Usage is pretty simple. Open a bundle (bundle.000) from either CD. It looks similar to the Windows explorer, on the left side are the directories and on the right side the files inside the currently selected directory.
You can extract a single file or the whole archive.
There are mainly Jpegs for the photos, the .bm files are rather small and seem to contain the images for the buttons, scrollbars etc.
The movies use the same format as Grim Fandango etc. and you can use my Smush player/converter to play/convert them.
The .s and .slb files are pure text files with scripts and layout data.
