Your tool is the first information I found about disk copy images.

Using other emlators elements is a constant, I did it for the 68k core
(from the atari castaway emulator) you did with the 68k core from a
sega genesis emulator. I also used a part of the mess lisa driver for the serial number reading.

Anyway, the disk_image source is a bit temporary & will be rewritten but the structure of that kind of function will remain the same. the comment will also remain.

I later found the correct checksum algorithm (from a mac utility written in clascal).
for (i=0; i<F->numblocks; i++)

     for (j=0; j<F->sectorsize; j+=2) {
mydatachks+=((F->sectors[i*(F->sectorsize)+j]<<8)|

(F->sectors[i*(F->sectorsize)+j+1]));

mydatachks=(mydatachks<<31)|(mydatachks>>1);

                                                 }

I also found the DART image format but I still need the correct coding of RLE compacted tracks.
