Possibly related to this commit? - https://github.com/mamedev/mame/commit/23045014acd8df88a44f2c019b3d11f960273a89#diff-fa577dabf351d508c0b0addacc6ad448 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. |
