I found this:
Note: Since ScummVM 2.7.0 the folder structure from the original media needs to be preserved. Older versions of ScummVM allowed to move files to the top level folder, while they now need to remain in their respective subdirectories. If your game is no longer detected by ScummVM, you may need to move back the files to their original subdirectories.

The game needs
CLUSTERS folder (with *.clu and swordres.rif file) MUSIC folder (Except 2M29.WAV in CD2) SMACKSHI folder SPEECH folder Rename speech.clu on CD1 to speech1.clu Rename speech.clu on CD2 to speech2.cluI moved the files *.clu and swordres.rif to CLUSTERS and now the game is running again!
But my folder SMACKSHI is empty. Can you list the files you have in that folder? In case these files still exist in my game folder, I would like to move them too.
Thanks!
