NIB is the simplest. NBZ is just NIB with LZ-alike compression applied. NIB files are: 0x100 header 1st 13 bytes ID = MNIB-1541-RAW Then 2 bytes for each track in the file, first is track number (always starts with 2 (track 1 is not accessible on 1541) and almost always ends with 82 unless file is truncated. The second byte is the detected density in the 4 MSB bits, and the sync flags in the 4 LSB. You can ignore the sync flags as they will be re-detected in the conversion anyway. Starting at 0x100, it is simple $2000 byte dumps of each track. This contains about 1.2-1.5 revolutions of overlap. That way the cycle can be detected and stitched back together. It would be nice to have the option to start data at the index signal... |
