After downloading and using the excellent BeebEm (Version 2.01), I found a DFS image creator called BBC Explorer. However, I would like to create ADFS disc images for the BBC Master side of the emulator in a similar way. Anyone know of any software that can do this?

As luck would have it, the BeebEm site pointed me to a few programs: DFS Explorer (does what BBC Explorer does), ADFS Explorer (for ADFS) and HADFS Explorer (for BBC hard disc images).
