ISO LBA Offset #5

Open AkBKukU opened 9 months ago

It may be possible to fix ISOs from blueboot discs by zero padding the start of the image to match the positions of the files indicated in the LBA positions.

I attempted a simple solution for this by joining BIN files and ISOs directly from a blue book disc without success.

Tests done:

Test 1

  1. Copy session 1 BIN
  2. Append session 2 BIN to copy
  3. Overwrite start of copy with ISO to make copy recognizable as ISO9660 filesystem
  4. Fail on attempting to extract files

Test 2

  1. Copy session 1 BIN
  2. Append session 2 ISO to copy
  3. Overwrite start of copy with ISO to make copy recognizable as ISO9660 filesystem
  4. Fail on attempting to extract files

If this is possible, a more precise offset from the start of the disc will need to be calculated.
