I'm on that firmware as well and it's been flawless. I have tested loads of GDI's and CDI's and everyone has worked perfect for me. No issues at all. Did you disable the 12v rail? I replaced my whole PSU to DreamPSU. My Dreamcast is cold even after running 3 hours straight.

How's is going now after resetting?

Hi there RetrogamerX ! With the new firmware it is working as intended , perfect so far. Have to try it out for a longer period of time to see if the "resetting" is still there but i havent got time to try it out yet.

Disable the 12v rail , i guess you mean on the Dreampsu (the original dont have 12v right =p) . No i havent , should i and if so , why ?

Best regards Florian :P

There's a cheap resistor you can add to the 12v rail which reduces heat since the USB-GDRom drive no longer pulls current from that rail.

Refer to the first page on this guide and you'll see a guide on how this is accomplished. Its easy to do. :)

Yes the resistor trick does the job well.
I also applied the resistor.

I'm new to this site. :D

I have only just received my USB GDROM for my Pal UK Dreamcast from 3do-renovation.ru
The problem I am having is every time I boot up my Dreamcast it will load to the blue menu screen. But when I try playing a GDI or CDI file from the Menu the system will hang. Like it as crashed. The controller will not do anything. I have tried using different pen drives and a SD card, USB hard drive. Doing the same thing all the time. I have tried formatting with Windows 10 Formatter, FAT32 Format, MiniAide Fat32 Formatter with 64k clusters. No matter what it will just hang at the blue screen. First thing I did when I got my USB GDROM is updating the OS to the latest one 'firmware update v 2017/09/05'. it updated fine with no problems and rebooted with out any problems.

I'm just wondering what may be my problem as right now I'm giving up getting. I'm using a Sandisk 16 Micro card right now and have tried a SanDisk 64GB pen drive that did not work. And a Western digital USB 1 TB Hard drive. That did work on booting to the blue screen. But crashed when clicking on any GDI or CDI file. Very much on the Micro 16GB Sandisk it will crash like the hard drive.

I have done the PSU Mod to disable the 12V line.. I have got a GDEMU and did it to that dreamcast too. That works fine with out any problems.

But this one I'm having problems with and as got me foxed.

Any help on this I will be grateful.

I have done the two bios mod on both of me Dreamcast's with a switch.
I'm just hoping I don't need to use a different system to get this to work. LOL

Thank you

Just a little update on my problem I am having with my New USB GDROM.

Last night I have been none stop trying to get the problem fixed. I have tried using different formatting tools and tried different pen drive's. Still doing the same thing on crashing the system. I Also tried a different Dreamcast from one that I fixed. I know both Dreamcast's work as they both have good working GD ROM drive's. But after testing with the other Dreamcast it's still doing the same thing. Both Dreamcast Model's are a [1] Pal. I'm totally confused on what to do. I'm wondering if it's down to the OS update or the board being faulty. If I can't get this thing working I may have to sell it on eBay as faulty and try and get hold off a second GDEMU. As I know the one I have got is working great and I'm very happy with it. I was thinking about contacting the person that makes USB GDROM from 3do-renovation.ru

But I really don't like waiting for it to come back to me.
I ordered it like 7 months ago or longer. I really can't remember how long but it was sometime until I got the thing.
It was ages! :(

This thing is giving me a headache on trying to get working. I have notice even that I have disabled the 12v line.
My Dreamcast is getting little hot. I Did the guide from reddit.com. My other Dreamcast I did it too with the GDEMU is not getting hot at all. So I'm a little bit nervous about it.

Anyway thank you

Hey Robbie,

Ah that doesn't sound that good.
So you have a VA01 Dreamcast?

Did you put the root_init.rar extract in the root of your USB pendrive?
And tried the root_init2.rar?

And what do you mean with crash? The dreamcast hangs?
Try to format your pendrive with fat32format in the start post but with a Windows 7 machine if possible.
