hmsa - Atari MSA / ST disk image creator and converter


hmsa diskimage [disksize]


Hmsa is little program to create compressed Atari MSA (Magic Shadow Archiver) and
uncompressed ST disk images and to convert disk images between these two formats.

MSA and ST image format saving code is same as in Hatari itself.


If you give only one parameter, the file name of an existing MSA or ST disk image, this
image will be converted to the other disk image format under a suitable new file name.

If the file does not exist and you give also a disk size:

SS Single Sided (360KB)

DS Double Sided (720KB)

HD High Density (1.44MB)

ED Extended Density (2.88MB)

An empty disk of the given size will be created.

Disk image format is recognized based on the file name extension (either .msa or .st).


Create a normal double sided empty ST disk image:
hmsa blank.st DS

Convert an MSA format disk image to an ST format one:
hmsa disk.msa

Use hmsa online using onworks.net services
