Description:

This converter converts Sega Dreamcast GDI image released in redump.org format to General GDI format.

Detail

Redump.org GDI and General GDI share with the same file extention name “.gdi”. That’s a file similiar but simpler than “.cue” file widely used in CD-ROM image to identify track filenames and track location in a whole disc layout.

But redump.org gdi image has several difference compare to the general gdi format.

  • Indentation white space in “.gdi” file.
  • Pause data is embedded in audio track file.
  • For games with split data track(more than 4 tracks and last data track is after another audio track), the last data track contains 75 sectors(1 second) of PreGap Data which is stored in the tail of its previous audio track in general gdi format, and 150 sectors(2 seconds) of Pause Data just like audio tracks.
  • Different track start LBA values caused by the above 2 differences.

Check the Usage section in this ReadMe file.

Bundled within are two versions. The source files Github, and a compiled windows binary w/ GUI. The GUI cannot be downloaded here as it is over 30 MB file size. You can download it at the link below.
