@Dbug: Attached is all I've found about 'The Hobbit'.
the_hobbit.tap and Hobbit, The (UK) (1982).tap are the same (size: 36212, crc32: c164a97c). I think the loading routine is broken for Atmos mode.
the_hobbit-full.tap - is working in Oric-1 and Atmos (this was made to avoid multipart tap, the same are both DSK's).
