GD-ROM dumping guide with dcdumper.

Contents

LD Area

Tools

Dumping

The LD Area is formatted like a standard CD-ROM, so should be dumped using the standard Disc Dumping Guide (MPF) with a CD-ROM compatible drive. The CD-ROM profile should be selected in MPF.

HD Area: swapless method (GD-ROM)

Tools

Dumping

  • In command line, cd (change directory) to the "DCDumper_ice" folder.
  • Run dcdumper [DriveLetter] -c446261 -df -ft -t0 -p20.
  • It will take several "PASS"es to get all matches - this is fine. Sometimes there is no progress for 30mins, but if you need to stop and restart the dumping process, it will continue where it left off. Just make sure you don't delete progress if you have to stop it.
  • When the HD Area dump completes, you need to convert it to its final form. Run ice.exe dense.bin 44990 > gamename.txt. This will produce a bunch of files starting with "Track 03" and going as high as however many tracks were on the HD section of the disc (as little as 1, as many as 98).

If dcdumper fails to run with an error complaining about MSVCP100.DLL being missing, install the Microsoft Visual C++ 2010 Redistributable Package (x86) to fix this.

HD Area: swap disc method

Tools

Dumping

Dumping the HD Area can take over an hour sometimes, during which your drive may make scary noises. Stopping your drive to allow it to cool down before continuing the dump later can help with ease of dumping. To dump the HD Area of the GD-ROM, a Swap Disc technique can be used. There are two ways to do the Swap Disc technique:

  • Prepare a Drive for Top Removal as seen in this video tutorial. Afterwards, set the top back onto the drive with screws removed, which allows for easy top removal. Make sure your drive lid is replaced perfectly, as putting your drive lid on unevenly can lead to the dump failing partially into the dumping process.
  • Pin Eject: Push the tray back into the drive quickly so the spindle will catch.

Process: A video tutorial for this dumping method can be seen here.

This method is the more reliable method for dumping GD-ROMs because:

  • The recommended TSST drives read GD-ROMs best. They do not support /c2 error correction, but...
  • DCDumper dumps disc segments multiple times and compares hashes for QC, and does not rely on /c2 error correction.

Dumping:

  • Insert the audio trap disc into the drive.
  • In command line, cd (change directory) to the "DCDumper_ice_startstop" folder.
  • Run startstop [DriveLetter] 1.
  • Remove the top off the drive.
  • Insert the GD-ROM and put the drive top back on.
  • Run dcdumper [DriveLetter] -c446261 -df -ft -t0 -p20.
  • It will take several "PASS"es to get all matches - this is fine. Sometimes there is no progress for 30mins, but if you need to stop and restart the dumping process, it will continue where it left off. Just make sure you don't delete progress if you have to stop it.
  • When the HD Area dump completes, you need to convert it to its final form. Run ice.exe dense.bin 44990 > gamename.txt. This will produce a bunch of files starting with "Track 03" and going as high as however many tracks were on the HD section of the disc (as little as 1, as many as 98).

If dcdumper fails to run with an error complaining about MSVCP100.DLL being missing, install the Microsoft Visual C++ 2010 Redistributable Package (x86) to fix this.
