 There are some other disk image formats, such as MSA and DIM.
-MSA is the format created by the Magic Shadow Archiver, it's very popular for use with emulators.  Thomas Huth has created a [http://hatari.sourceforge.net/files/msa-0.1.0.tar.gz Linux program] to convert between the '.ST' format and the '.MSA' format.
+MSA is the format created by the Magic Shadow Archiver, it's very popular for use with emulators.
 The DIM format is created using FastCopy.  It is the same as the '.ST' format, but with some additional information in a 32-byte header.  You can convert this with the following command, which simply strips off the first 32 bytes:
