    Took mine about a month from payment.


    Ill be testing some more stuff but sadly I won't have enough time to contribute enough to generate a good list.

    Is this question for me?
    The PNY stick was bought from Walmart in official PNY packaging.
    The USB-GDROM, I bought it directly from MNemo himself.

    If Walmart, should be an official one, so. Don't let the packaging foul you, pirates made lot of progress on this aspect of things.

    Does anyone know if japanese_cake's DC bios has issues with the USB-GDROM Controller? I may flash my bios with it to get that sweet intro.

    Beware of Amazon: only buy when sold by Amazon, not when sold by a third party and shipped by Amazon or when sold and shipped by a third party.

    Good to note. Thank you.

    I grabbed more43 USB sticks with verified good sectors. Ill test them with CDI, GDI, and QoL testing. I won't be able to test firmware updating b/c im on the latest FW which isnt even on MNemo's site yet.

    I was wrong. I did a full format with a Ease Partition Manager.
    This stick now works flawlessly on FAT32, 64K Clusters, without Quick Format.

    Also curious about the overclock compatibility...

    I do know for instance that for the Saturn it was stated 'dangerous' to flip the 60Hz switch while the console was running if you had a modchip installed, as the voltage increase could fry the said chip...
    So I'm wondering if the same theory applies to the DC, as I have a 12v fan attached to the back, connected on the same switch which enables the overclock to cool the unit a bit more. Now I'm not gonna flip that switch at random, but do have some questions...

    - would the fan (if running) drop the voltage to a normal 12v or not, as I read contradicting statements in previous posts?
    - would the overclock prevent the USB mobo from running decently, or even frying it as it runs the console at a higher speed?
    (I think not...correcty me if I'm wrong)

    If the overclock would make the DC USB run similar as with a regular GD-drive (bar a couple of games running too fast) and has no voltage impact on the USB hardware, then I'd guess the extra cooling helps, and I would have the OC enabled almost all of the time..

    My WIP-DC is still opened up, so I can't test myself, but might consider purchasing an extra console just to have this USB hardware running untill I have the initial DC running again...



    EDITs:

    - Am I blind or do I see two USB connecters on top of each other??
    Why not for the external versions....it would be awesome if he makes a version with one internal and one external port...
    http://www.stoneagegamer.com/dreamcast-usb.html

    - on Mnemo's order page it states the following:
    - address for shipping
    - phone
    - your account
    - item(s) and quantity

    I assume he just wants your PayPal mail address??


    - I'm also looking forward to pics of a successful internal HDD mount.

    Don't enable or disable the overclock while the console is running, it will crash unless you do it in under 4ns, AND even then it probably won't work unless you're extremely lucky. AFAIK it's not dangerous in itself, but why risk it?

    Wasn't planning on doing this whilst running, but if enabled before powering up, it will work without any possible hickups, you think?

    My v5 has two usb ports. I use the top one since its flush with the GDROM plastic. Either he did this to have that flushness or idk why else. I never tested the bottom port.

    Yep he is only asking for the paypal address for "Your account"

    I thought maybe the 2 USB ports might be for some USB drives that use two for power. I had a USB drive a while back on my PC that used two connectors in order to work correctly for some reason. It's the same for when you use a WiiU console that has had it's Vwii IOS modded for USB access, as one port on the console is not enough to power the drive like you could on an original Wii.

    However, only used the one port on the UGC and its fine.

    Just to add - I have tried my over clocked dreamcast with my GD emu board and it ran ok (although I only tried it briefly a while ago) - I should imagine this unit will be ok too.

    I noticed he updated the page to USD with shipping info... So its safe to assume he is still making boards and shipping them... but to what i Understand he just pumping out boards right now for 3do and dreamcast. He might give small replies if you are lucky... but at best you will get a confirmation and thats it.

    I spoke to him recently regarding my order, which I received and from the looks of it, he is swamped with orders.

    How long did it take for you to get yours? I wouldn't be surprised if he is super busy, he's selling a very unique product.

    It took me quite a while to get hold of MNEMO. Eventually I got a reply and had two boards mailed out to me in Western Australia on the 28th September which, have yet to arrive...

    About 2 and half weeks from the day he received the payment.
