The build/makefile creates the psys disk image (psys.img) by
concatenating psys.vol and blank.vol (after adding track 0 contents to
each). psys.vol and blank.vol are recognized by CiderPress and
CiderPress can be used to add/remove files from these volumes.
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:
https://github.com/robosnacks/psysimg.
There is currently no support for floppy drives.
