There has been an update to Nibtools. In case you haven’t heard of Nibtools it is used to image a Commodore disk to your PC and to write a disk image (D64, G64) back out to a real Commodore disk. I use it with CBMXfer program. Nibtools has options to read/write out to track 40, half track, fix short tracks, reduce gaps, and more.
This update includes a number of fixes.
Can deal with Half-Tracks better
Now creates Standard G64 files
Patch the drive code foe use the a Zoomfloopy
The update is build 587 and can be found on the C64 Preservation Page
