The disc contains two distinct areas, a Low Density (LD) Area and a High Density (HD) Area, physically separated by a ring. To get a good dump, you need to extract both Areas from the disc.

| - | If you have any of the officially released discs for the Dreamcast or any of the above mentioned arcade systems, you are pretty much guaranteed to have a GD. The Dreamcast did however support loading of [[wikipedia:MIL-CD|MIL-CDs]], which lead to a number of unlicensed software being pressed on regular CD-Roms. Check for the GD-ROM logo on the disc or check the reflective side of the disc for a visible LD/HD Area divide if you are unsure.

| - | The LD Area is a standard CD-Rom, so it will be the only data to display on the disc when browsing the disc in Windows Explorer.
| + | '''Dumping''' |
| - | | + | * Open command line interface app |
| - | ==Dumping the HD Area==
| + | * cd (change directory) to the location of the dreamdump app. |
| - | To dump the HD Area of the GD-Rom, a Swap Disc technique is used.
| + | * Dump with the following command: dreamdump disc --drive="[drive letter]" --image-name="" |
| - | There are two ways to do the Swap Disc technique:
| + | |
| - | * '''Prepare a Drive for Top Removal''' [https://www.youtube.com/watch?v=cJF1n4l4OGA&list=PLQB0cW1F4d0umPPY-vU1BHhjH1iyry2Yd&index=2&t=2s as seen in this video tutorial]. Afterwards, set the top back onto the drive with screws removed, this allows for easy top removal. This is the most reliable of the two ways to Swap Discs. Make sure your drive lid is replaced perfectly, putting your drive lid on unevenly can lead to the dump failing partially into the process.
| + | |
| - | * '''Pin Eject''' - which isn't as reliable as the Top Removal way. | + | |
| - | | + | |
| - | Notes:
| + | |
| - | * Dumping the HD Area can take over an hour sometimes and your drive may make scary noises.
| + | |
| - | * Adding the command "/be pack" [can sometimes/always?[http://forum.redump.org/post/105799/#p105799]] be helpful when dumping.
| + | |
| - | * 1x read speeds can be helpful or even necessary when dumping GD-Rs. | + | |
| - | | + | |
| - | ===Method 1: DCDumper===
| + | |
| - | One of the two ways to dump the HD Area is with DCDumper. A video tutorial for this section can be seen [https://youtu.be/KjCYtXVhgS4?t=4 here].
| + | |
| - | * Insert the Audio Trap Disc to an HD Area [[DiscImageCreator:_Optical_Disc_Drive_Compatibility#GD-Rom|compatible 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. If you need to stop (sometimes there is no progress for 30mins) and restart the dumping process, it will continue where it left off - so don't delete progress if you have to stop it.
| + | |
| - | * When the HD Area dump completes, you'll convert it to it's 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 issue.
| + | |
| - | | + | |
| - | ===Method 2: DiscImageCreator===
| + | |
| - | The other way to dump the HD Area is with DiscImageCreator
| + | |
| - | * Insert the Audio Trap Disc to an HD Area [[DiscImageCreator:_Optical_Disc_Drive_Compatibility#GD-Rom|compatible drive]]
| + | |
| - | * In command line, '''cd''' (change directory) to the folder containing "DiscImageCreator.exe"
| + | |
| - | * Run '''DiscImageCreator.exe stop [DriveLetter]'''
| + | |
| - | * Remove the top off the drive
| + | |
| - | * Insert the GD disc and run: '''DiscImageCreator.exe close [DriveLetter]'''
| + | |
| - | * Then run the dumping command: '''DiscImageCreator.exe gd [DriveLetter] foo.bin [DriveSpeed(0-72)] /c2''' (Note: " /c2" is only for use with compatible Plextors)
| + | |
| - | * Dump multiple times until you get an error-free dump (check the Command Prompt output after DiscImageCreator finishes dumping)
| + | |
| - | | + | |
| - | ==Submitting your dump info==
| + | |
| - | Here's an example submission: [http://forum.redump.org/post/105798/#p105798]
| + | |
| - | | + | |
| - | We'll presume you've used Disc Image Creator for you dump in both LD and HD Areas.
| + | |
| - | | + | |
| - | Open your "!submissionInfo.txt" file from both your LD and HD Area dump. Copy in the additional track information from your HD Area !submissionInfo.txt file into your LD Area !submissionInfo.txt file in three sections:
| + | |
| - | * "DAT"
| + | |
| - | * "Cuesheet". When combining Cuesheet data for LD and HD Areas, paste "REM SINGLE-DENSITY AREA" at the top of the cuesheet, and "REM HIGH-DENSITY AREA" in a new line after the LD Area cuesheet into, then finally the HD Area cuesheet text.
| + | |
| - | * "Write Offset"
| + | |
| - | | + | |
| - | Fill in Ring Code data and any relevant Comments. Post on the Redump "New Dumps" subforum.

GD discs were used by the Sega Dreamcast console and Sega NAOMI, Sega NAOMI 2, Sega Chihiro, and Triforce arcade systems.
The discs contain two distinct areas, a Low Density Area ("LD Area") and a High Density Area ("HD Area"), physically separated by a ring. You'll need to dump both areas of the disc, each requiring different drive models and methods.
The LD Area is formatted like a standard CD-ROM, so should be dumped using the standard Disc Dumping Guide (MPF). The CD-ROM profile should be selected in MPF.
