However, there is currently no straightforward way to extract the
volumes from the disk image. If you are good with a binary disk
editor, you can do it that way. Please contact me if you are
interested in pursuing that.
To extract volumes from a disk image, Andrew Davidson has created
a nice Python script that can extract p-System volumes from an
existing disk image file. The extracted volume can be manipulated
by CiderPress. The script is also capable of re-inserting a modified
volume back into the disk image file. This tool is available at:
