Simon: > Good, bad or ugly?
Sounds OK. Some things I thought up for 'PC' minded format: Have a format that consists only of track fragments (sectors). Each fragment had a 6 byte header folowed by at least 4 bytes data. So the smallest fragment was 10 bytes and largers 1024 (length/4-4 in one byte). Depending on the fragments type it contains all gap types, address marks, sector data. Besides the diskinfo there are types for file formats ID , end of image marker and discription. As with the other idea, only the used or required fragments are included and each of these track fragment could be anywhere in the image.(emulator should build a ordered offset table) Standard images can have just the sector fragments and protected disks can add extra fragments to rebuild a whole track. Ugly ? As for a encapsulating format: zip dsk,sad,sdf,fdi and rename the extension. Shoot me for this one ! Edwin
