(3) Others

  1. Added support for multiple indexes on CDDA tracks.

  2. File output with Session and File commands is now possible.

A.4 Changes from Ver.1.50 to Ver.1.60

(1) Provision of 32-bit version "XBL D32"

(2) Functional improvement

  1. Removed the limit on the number of times specified in the Trigger and Eors command files.

  2. Fixed so that the maximum number of file interleaving and channel interleaving can be specified.

  3. The file processing method has been improved to improve the processing speed.

  4. Changed to display the file name in the message during build work.

(3) Corresponding to the failure that occurred in the version before Ver.1.50

  1. Fixed an error in the file size when the SubHeader command was specified.

  2. Fixed a file interleaving submode error.

  3. Addressed an issue where the TOC file contents would be invalid if the file was not defined in the track.

A.6 Changes from Ver.1.70 to Ver.1.71

A.7 Changes from Ver.1.71 to Ver.1.80

(1) Specification change

  1. When the p subcommand and otf subcommand are specified, the output destination of the TOC file, RTI file, QSB file, SCT file, and OTI file is set to the same position as the PVD file.

  2. The default creation date and time of MPEG and channel interleaved files is the time of disk build.

  3. The date and time of the root directory can now be specified with the Volume Modification Data command.

(2) Troubleshooting

  1. If you do not define the Pause command for a CDDA track first on the track, a problem will occur.
