The problem is probably that there is no listing for the required datafiles of SCI games on the wiki in spite of them being supported. To the OP, for the games you have you should just need to copy everything from the original media to your hard drive to add the game.

For SCI, you usually need to copy almost all of the game files, except the executables and install.*, which are usually around 250KB or so, so you don't really save much.
