Pulling GD-ROM data from an HKT-05 Dreamcast GD-X unit

[Mark30001]

Nearly half a year ago, an HKT-05 Dreamcast GD-X Duplicator finally came into my possession. The only information that was known about these units is that they were able to duplicate GD-ROM discs while connected to a maximum of 4 Katana GD-Writers at a time, and they were able to dump GD-ROM data onto an internal SCSI hard drive. Without any manuals or documents of any sort I was unable to use it to its full potential. After many attempts to pull some data, I finally gave up and called it quits.

Today, I decided to program the GD-X Duplicator to dump one last GD-ROM disc, a Dreamcast SYSTEM-DISC 2. After it was done, I removed the SCSI hard drive and connected it directly to an Adaptec 2940U SCSI card connected to my PC. To my success, I was able to view dumped data off of the hard drive!

In approximately 15 minutes, I was able to successfully dump data from a Dreamcast SYSTEM-DISC 2 (nearly 1 GB of data)!

Congratulations Mark!

Congratulations!

I am not that technical, just wondering what the possible benefits are of having this GD-ROM available?

So the only thing you can get it to dump is the system disc? Any luck with other discs now?

Show us more pics (screen shots and such)!

There you go, Sothy. Read that. Explains all.

The sad thing is that I had formatted the HD because it appeared empty at the time (I never inserted it directly to my PC to try to recover any content). I've already found some source code in a Dreamcast Dev box I received not too long ago. I believe it was named "Chunk_Test."

The files dumped by the GD-X duplicator can be extracted using EXTRACT.EXE. I've attempted to dump a System-Disc 2 and Sonic Adventure Japanese so far, and they were all successful!

I find this method easier for dumping HKT-06 GD-R betas of Dreamcast games...

I still haven't been able to convert any of the dumped images into selfbootable Dreamcast games, but I'm working on it!

Are you using blank GD-Rs? If not, I'd guess that might be why.

Blank GD-Rs?

I'm trying to find a way to burn this data onto a CD-R media instead. There's no use to burn a GD-R of a System Disc 2 when they are made to read GD-Rs.
