Introduces constant fields for respective debug module names, replacing the hardcoded ones. This is done to standardize the naming convention, reduce redundancy and potentially avoid any typos or name mismatches across the project. This change makes the code more maintainable and easier to update in case module names need to be changed.

/* Some information on the file format from Michal Necasek (www.os2museum.com):
|
|
*
|
|
* The DDI diskette image format was used by the DiskDupe DOS utility,
|
|
* developed by Micro System Designs, Inc. of Cupertino, California in the
|
|
* early 1990. DiskDupe was used to drive floppy autoloaders/duplicators
|
|
* and disk image functionality was a fringe feature.
|
|
*
|
|
* All information about this format was obtained by analyzing available image
|
|
* files and may not be entirely accurate.
|
|
*
|
|
* The DDI (DiskDupe Image) format is very simplistic, only supporting
|
|
* standard PC floppy formats. It was not intended as a generic floppy disk
|
|
* archival format.
|
|
*
|
|
* There is no compression and no checksums, but provisions are made to leave
|
|
* out unused tracks. There is a track map at the beginning of the image.
|
|
* The image header is the same size as a single track; the track map uses
|
|
* this fact and gives the starting offset of each track in units of one
|
|
* track's worth of data (e.g. 7.5KB for 1.2M images).
|
|
*
|
|
* There is a unique signature ('IM' followed by several zeroes), which means
|
|
* that DDI files are easy to recognize.
