    (This bios dislikes MIL-CDs)

    Next I'll dump the flash for the said console. :nod:

    What's in the bios code for it not to like cd-r's.

    wonder could it be made to region free and cd-r able?

    They just changed the KABUTO (boot loader). it's like 99% the older bios.

    If there's no problem with that for the forum I cam put a link here. :nod:

    Thanks a bunch!

    Given that link83 modified devkit bios is allowed, it's safe to say that this one too is ok!

    Cheers, and thank you!

    I cheated ! :lol:


    I put two BIOS in parallel. Booted from the old one, switched the bios and dumped the other one with the vulnerable code already running in RAM. :nod:

    Then I had HTTPD-ACK do it's thing. :thumbsup:

    Nice :)

    I was imagining the usage of a System Disc 2 to launch a program put on GD-R, but your method is cooler :)

    Burning an GD-R for doing something like dumping a bios ? That would be silly and wasteful, honestly. I'd rather wire it up on some board then use an chip programmer for doing the job. :shrug:

    I don't even have the hardware to burn an GD-R... And the System Disc is beyond rare ... :lol:

    I could do it, but like you said, it would be a waste of a good GD-R, so I never did it :)

    Is it really 2.4? Not 2.1? If so it'd be cool to hqve a picture of the mobo. I had never heard of VA2.4 only 2.1!

    Thanks!

    Would V2 dreamcast's be able to run CD-R's (MIL-CDs) if the bios was swapped with the code from a V1 Bios?
