Possibly related to this commit? -

As mentioned Airborne Ranger ('airborne' in the softlist) also fails to load, as does a GoodCPC version of Barbarian.

Seems to set flags incorrectly for the FDC Read Deleted Data command.

These disks check that sectors with deleted mark set can still be read. This works as a form of copy protection/modification detection, as conventional copy programs won't copy deleted sectors, and deleted sectors can be overwritten when a disk is written to.
