## NAME

## SYNOPSIS

## DESCRIPTION

These tools are used to handle DMK disk images.  Those images can represent strangely formatted disks and are used by [*openmsx*(1)](/openmsx/1.md) to allow correct emulation of disks which use those features for copy protection.

All tools except *combine-dmk* have a *--help* argument which explains their usage.

**empty-dmk** creates a new empty DMK image file.

**dsk2dmk** creates a new DMK image file and initializes it with the contents of a DSK image file.

**svi2dmk** creates a new DMK image file and initializes it with the contents of a special image file.  See *svi2dmk --help* for more information.

**svicpm2dmk** creates a new DMK image file and initializes it with the contents of a special image file (CP/M version).  See *svicpm2dmk --help* for more information.

**der2dmk** creates a new DMK image file and initializes it with the contents of a DSK image file.  In addition, the error state from a DER disk error file is used to initialize the disk's error state.

**combine-dmk** reads a series of files named *DMK-tt-h.DAT* where *tt* is the track number, and *h* is the head, and creates a DMK image file named *out.dmk*, which is initialized with the data from those files.

**analyze-dmk** reads a DMK image file and prints statistics about it to the standard output.
