I bought this curio CD from Yahoo JPN some time back. It appears to be an audio reading based on the novelization related to this game. It's mainly dialogue interspersed with a large number of varied musical numbers and cues (unrelated to music in the SFC game). It's quite long, clocking at a hair above an hour.
The SFC La Wares seemed like a very rushed product. It's my guess there's plenty of material and scenes in the novelization they cut from the game. I can only pick out things here and there, but perhaps it might be an entertaining listen for you Japanese speakers here.
