◆ hasChanged()

virtual bool openmsx::Disk::hasChanged ( ) const

inlinevirtual

Has the content of this disk changed, by some other means than the MSX writing to the disk.

In other words: should caches on the MSX side be dropped? (E.g. via the 'disk-changed-signal' that's present in (some) MSX disk interfaces).

Reimplemented in openmsx::DirAsDSK.
