    It should be known by now that I messed around with RVT-R discs; hacked a drive to dump them and made them run on a retail Wii.

    So I thought what's next? Let's kick it up a notch!

    Burn RVT-R discs, but as a poor student :crying: I can't just buy an RVT-R Writer ...

    As there are basically no DVD-ROMs that burn RAW and finding a drive that could be easily RE'D seemed to much effort I tried a different way I've found the drive name of the RVT-R Writer in some RVL SDK docs

    so I thought that just maybe they were sold normally aswell but nope no SW-9585S in the wild but I found a SW-9585C ebay.com, so I asked someone to buy it for me and do some tests.

    First try running the RVT-R Writer firmware updater no luck "no compatible device found" after some RE'ing of the tool I just patched it to accept anydrive and it happly flashed the firmware to the SW-9585C and big surprise not only did the drive still work (puuh) it turned into a real SW-9585S!

    Trying to run the sdk tools on it didn't work, at this point I let the drive be sent to me and today it arrived...

    After some RE'ing it turned out that the tool was looking for a certain VID and PID of the USB2IDE device ( vid 0409 (NEC) pid 0193 ).

    A quick patch resolved that issue but another one was still there it checked some kind of ID aswell and with my USB2IDE device that part was always 00000000000 I just patched that check out aswell and run the rvtwr tool and ...
    SUCCESS!! :dance:

    long story short I can now burn RVT-R discs and I also got 10 empty ones :D
    (the drive I got was a "MATSHITA DVD-RAM SW-9585B10008/03/05BZQ2A.2007" <-- inquiry)

    how much did I spent? with two times shipping (within USA and to Germany) $70.


    edit:
    Played a bit more with it, did one successfull write and verify and found out that you can simply read burned RVT-Rs with it, currently dumping one with 5-12mB/s via ImgBurn :D

    edit2:
    tmb helped me to make a RAM dump, he's messing with it now :).

    If anyone needs anything burned(or dumped) just ask me (from looking into the FW and all it seems to be possible to burn NR discs aswell!)
    I do have some empty RVT-R discs, but no empty NR discs.

    Note: It is not possible to burn RVT-R(/retail Wii) dumps via the nintendo tools only .rvm/.gcm images.

    I m a bit confused. The NR writers were standard Matsushita drives with a special firmware (The Wii uses the same drive with a different firmware as well I think), which I happen to have come across a lot on the internet. How is this different?

    Amazing!
    How did you find the OEM of the drives? Who was willing to tear apart their Rvt-R?

    From the same era, mac computer external super drives are super cheap.

    What flash utility did you use? Any chance you might post a rar of the files so I can try to mess with my superdrive?

    I used the flash tool that comes with the RVL_SDK to update an RVT-R Writer to a newer firmware, I highly doubt it will work with uhm a "super drive" ??

    It's just the nickname from back then. The drive you flashed is called a super drive back then. It's just a trademark name like lightscribe.

    It's panasonic dvd-r from the same series of drives.

    I've got the same drive, in a macbook. It was £30 on ebay (the one that came with it was dead, though I still have it in a box, doesn't read discs) so I could attempt to flash to that if anyone wants to test this.

    Super Drives were often OEM drives with an Apple modified firmware to disable such worthless features as DVD+R support. Not sure why but Apple only really wanted DVD-R burning capabilities with a lot of their Macs. Usually could flash the drive with the retail firmware and regain all functionality though.

    Some technical details:

    - The firmware handles all the NR/RVTR-Disc specialities. It knows about the sector offset, the scrambling and how to detect an NR/RVTR-disc based on the DMI.
    - As it's based on DVD-R (minus, not +), the PFI/DMI come pre-written on the disc. The DMI is what differentiates a recordable disc from an NR/RVT-R disc. If someone finds totally empty DVD-R, we can produce compatible NR-discs (by writing the leadin).
    - There is no special stuff happening when burning, it just burns the image 1:1. In theory, you might even be able to use a tool like imgburn. The drive firmware does all the work.
    - Since there are many specific details in the firmware, porting that to an incompatible drive is probably difficult. But looking at the firmware carefully might allow a mn103 hacker to apply similar changes, maybe not as sophisticated, to other panasonic-based drives.
