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

[japanese_cake]

Then if you could share it, it would be perfect ;)
Anyway, thanks for sharing this!

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?

[l_oliveira]

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:

[iNub]

I'd sure love to get that BIOS and flash it for testing... hope you get a thumbs up ;)

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!

Contains the BIOS and FLASHROM for an VA2.4 motherboard (no separated GD drive board). :thumbsup:

Very interesting !
How did you manage to dump it ?

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:

[T_chan]

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

[zouzzz]

Great job !
Thanks l_oliveira

[Mystical]

nice one, thank you

Could someone please mirror this?

[atreyu187]

Never thought I would ever see this but I guess I can eat mt words on that. Thanks for the contribution.

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?

[Braintrash]

Yes.
Mine does.
