In order to get the intro and ending sequences from the 3DO version, you
need to have the original 3DO Star Control II CD. Create an image from
the CD and use uqm3donix* to extract a tarball with the videos from it.
The reason for this is because the 3DO uses its own proprietary disk
format.
Save the file as videos.tar and use "nix-prefetch-url file://\$PWD/${name}" to
add it to the Nix store.
