    Hi I recently got a Dreamcast HKT-01 dev kit and I hooked it up via vga and got nothing but a black screen. And I made sure the rotary switch was set to 4 and that the first 2 dip switches were switched to on. Any help would be appreciated.

    It could be in CPU mode (Where it will boot to a black screen and you have to start it from within Codescape). Have you any way of connecting this to a computer?

    I just purchased a SCSI card for my old windows xp computer (but it won't arrive in the mail till tuesday). And I also have the SCSI cable, three terminators, and the katana SDK r10. But after I connect it to my PC how would I go about getting it out of CPU mode?

    You have to run DAcheck and if everything is detected ,when you exit it it will ask you
    what mode you want.

    Well I have everything hooked up, I installed the correct ASPI drivers and my pc recognizes my SCSI card and the Katana. But when I go to open DAcheck it gives me an error that states there is no host adapters present. And when I try to run codescape it says there was no DIAL found. Also even though my pc recognizes the katana its listed under other devices in device manager.

    Never mind I got it switched to os mode. Thanks everyone for your help. Now the only thing is that its not reading discs. I can hear it spinning. Dead laser?

    There's a common fault with bad solder joints on the internal connectors which cause problems with the GD-ROM drive on these units. I wrote a few words about my experience with this on my own unit:
    http://www.assemblergames.com/forum...-GDROM-Problem&p=677315&viewfull=1#post677315
    Since then, I've heard of numerous other cases of the same kind of problem with the Katana units. If you're handy with a soldering iron, you can fix it yourself, otherwise get someone who knows what they're doing to re-solder the connectors.

    Thank you for the quick response. Could you possibly post some pics on were these bad solder joints are located?

    Nothing on hand, but here's what I could find online:

    See that high density connector on the mid-lower right side of the board? Those were the problem in my unit. There's three stacked boards, with two connectors on this middle board, and the other half of each connector on each of the other boards. I touched up all the joins on my unit, but it was this middle board in particular which seemed to have the bad joins IIRC.

    I know its been a while since this thread has been active but I thought I would shed some light on a certain issue. Sometimes when the gd ROM drive spins a disc but doesn't read it, it can mean the drive is also in emulation mode. I had to go into gd workshop and switch it to gd ROM mode.
