USB GDrom Thread

I'd like to buy one too. Preferably for around what he had been selling them for.

 

Hey there, I'm looking to order/pre-order a USB GD-rom drive. If anyone here from the US sells them, please PM me.

 

I took delivery of one of the most recent batches of MNEMO's USB GDROM boards, it arrived on Thursday last week. I'm pleased to say after fitting it this weekend it is everything that was promised & an absolute doddle to install.

Unfortunately one of my three Dreamcasts (the one with the dodgy GDROM drive) seems to have stopped outputting video, although the logic is still working as it boots games. Damn. Ah well, I still have two working ones left now to look at modding the PSU to prevent any overheating!

 

This forum is probably going to get a lot of traffic as he is listing SuperG as the main contact on his How to Buy page.

yeah he already posted that he will update with buying details when he can

 

Yep, he's probably bombarded with pm (that's the way I ended up here )

 

hello guys

i just want to share the new fw as of 04/16/2016 with you , i got an email from mnemo with the link to the beta fw to test out , here the text in my mail i got from him , have fun

" Before release new firmware I need couple betatesters with final ver "external USB"(April-May 2015) like as yours USB-GD.
https://yadi.sk/d/_DssKZW5r3jYf
Test it and give me feedback. "

( i dont have time atm to test it my self but feedback about D 2 disc swapping would be nice , i hope he fixed it )

 

I might be the guinea pig for this, this weekend. Hm, I wonder what is new about it

 

Updated firmware but is not showing the new date, apparently I am still on a August 2015 firmware.

Is this only for external USB or should it work on internal also?

 

That's what's changed in the beta firmware, I opened it with a hex editor, changes ar at the top of the file.

Feedback:

1. Disc swapping works for D2.
2. Other multi disc game don't work with disc swapping.
3. Swapping images is in reverse order now, so loading image 2, 3 & 4 now load as 4, 3 & 2 :/
4. GDI games aren't always loaded properly, you're taken to the DC bios screen.
   (Happens with swapping an image also)
5. Everything else seems to work the same.

Tested on my V1 UGC.

 

To your 4th point, does that mean that GDI loading is more stable on prior releases? Fixing D2 isn't enough of a reason to update the firmware if it breaks other features

 

Correct, I had no issues with GDI games loading, until I installed the beta firmware.

It doesn't happen all the time, but it's happened a few times when I was testing.
I made a video for mnemo & it happened when doing the video so hopefully when I send it to him he can fix the issue.

 

The beta update has also broken disc swapping for my unit, it doesn't detect that the lid has been opened.

Certain CDI's aren't booting either and just put me at the music player screen. Is there any way to downgrade?

[edit]

Disk swapping does work but is kinda random as to whether it changes the disc or just "empties" the drive.

 

Someone got Ghost Blade to run on USB GDROM?

I don't have the original game and tried a downloaded version (CCD/IMG/SUB). Since USD GDrom didn't like ccd, I tried to convert it do cdi: first mount image in daemon tools and created a new image using discjuggler. But everytime the dreamcast go to cd player (track selection). I also found a cdi converted version for download but same results.

Some people from this thread said that after a firmware update GDEMU now is working. Do us with USB GDROM will also need an update? Any chance to Mnemo do it?

 

I got a new one today from mnemo, it's the full firmware this time 3mb.
(Cannot share & after the last beta I installed I don't want to, as I don't want features broken & me getting the blame)

What I can say is it seems GDI loading is back to normal & he's added a new txt string under Region Free: on "Select Image for swap - <x> button"

Codebreaker cheat discs doesn't boot now , game shark cheat disc still works.

Also the reverse order swap images are still there.

Update:
I fixed the above Codebreaker CDI not loading.
I had to extract the CDI & rebuild it with bootmake.

 

Thanks for posting this Rocky. Personally I don't see a reason to update mine so I'll skip this one. Would be great to have a nicer UI but the thing works.

 

Can someone test the swap order for GDI files please?

I'm sure if I selected images in a certain order they would be swapped in that order.

Old firmware
I pick:
Image 1
Image 2
Image 3

Opening & closing the lid:
Image 1
Image 2
Image 3

I cannot test myself as well I'm on the latest beta firmware.

Currently this is what happens & I'm sure this want the case but mnemo said he hasn't changed the swap image code.

New firmware
I pick:
Image 1
Image 2
Image 3

Open & close the lid:
Image 3
Image 2
Image 1

 

This is the reply I received from Mnemo about Ghost blade and Pier solar two games that doesn't work with USB GDrom:

Good news.
Thise games will be implemented in July Firmware update.
Now I am busy with launching mass production.

 

good news

 

Very good news!

Mnemo also replies to me with a funny comparison table:
