Just FYI: There is a new .G64 disk image file format on the way. It is
basically defined and finished, only the docs have to be written up.
It is a (AFAIK) a vc1541 disk image in GCR format. It will be supported
by several emulators and can handle more than the usual 35 tracks.

Also there is the .x64 format that already contains an amount of 
information of the disk image. The header is a fixed 64 byte field
just before the "d64" image.
I do not know much of it, but it is supposedly much more flexible and
informative than the plain .d64 file. However, .x64 did not become
the emulator standard when it was invented (with the x64 - i.e. now
VICE - emulator).
