Yes indeed...  ;D

DMS format is the best known on AMIGA to compress image of a disk.
But this format has several problems in addition to the damage of time (scratched CD, failed hard drive, bad transfers ...).

So I wrote a program for testing, decompress and repair DMS files :

For the moment :
 - Decoding the header (overall and track)
 - Checksum16 (U.CRC)
 - CRC16 (D.CRC)
 - Simple (RLE), Quick and Medium unpacking algo (unpack in memory for the moment)
 - Repairing a faulty byte (the routine is written but not yet implemented  and very slow)

I started two weeks ago to learn a new language ... work in progress  ;)

Small issue....

In your latest 'Commodore Amiga - Coverdisks - [ADF] (TOSEC-v2012-04-10_CM)' DAT you're missing SHA-1 hashes. Remember all DATs now need CRC32, MD5 and SHA-1 so remember to enable it in your DAT creator.

I have some ClrMamePro Dat2Dir templates here if that's what you use:
http://www.redsplinter.com/tosec/TOSEC%20(multi%20files).d2d
http://www.redsplinter.com/tosec/TOSEC%20(single%20files).d2d
though you will still need to manually copy&paste (then update) the header.
