I've 'inherited' an official Sega bootdisk from a defunct developer... Is it of any use? Can I use it to boot backups?

Or, as I suspect, is it just another disk to sit in my game collection?

I'd love to help, but like everyone else here (I assume), I have no clue.

Coincidentally, could you scan this thing or something? I'd love to see it.

Yeah that would be cool! I wonder if I bypasses the search for the security code at the rim? Wasn't the boot disk made available to developers so that they can use their CD-R's to test their code? Or am I wrong?

Here is about all the info you may need on this interesting CD....... (Note that it wasn't made by me... but by Adam.....):

"From: gamescan@pacbell.net

Date: Sun Aug 19 18:12:21 EDT 2001

Subject: Re: Question: (Was Re: The best Saturn news...)

Sega, unlike Sony, has never made special "debug" systems for testing betas.

Debugging was done on the dev consoles and the testing was done on standard

units with key discs. What you have is one of the key discs.

The Saturn required a set of two key discs. One for third party games and

one for first party games. What you have is the "Black" third party key

disc. The first party key disc is the "Red" disc.

In order to play a CDR on the Saturn you need to load the proper key disc

and then load the CDR. The Black disc will boot any third party CDR while

the red disc will boot any first party CDR. The system discs do not disable

the county code check, they only disable the CDR security check. However,

the system discs themselves are not country coded and will work in any

system out there.

Once the Saturn has been booted with the key disc, the CDR security check

will remain disabled until the power is cycled. This was done to allow for

multiple disc games as well as to allow for the swapping of different games

without having to do the boot-disc cycle again.

The Maker ID on the discs are unique to whomever originally licensed the

discs, presumably to prevent them from being sold.

Sega kept the same system with the Dreamcast, however only one system disc

is used instead of two. Interestingly enough the Dreamcast system disc is

labeled Dreamcast System Disc 2. I don't know if there ever was a System

Disc 1 for the Dreamcast or if the 2 was to denote that System Disc 2 was

for the DC while System Disc 1 was for the Saturn.

What you have is quite rare and hard to find. However, most people don't

know what the #### it is so when they do become available the discs tend to

go cheap. I remember about a year or two back a Saturn system with a black

disc popped up on eBay. Someone asked about it here on the list and I posted

an explanation. I figured that it would go for a sum of money so didn't

bother bidding on it myself. Heh, I was quite surprised when the package

closed at around $75. Whoever got that (was it you Jason?) got one #### of a

deal. Had I known it would have gone for so cheap I would have snagged it

myself.

Adam"

Hopefully that is more than enough Info.... if not, you could always E-mail him =) TTFN

Yes, but wouldn't the boot disc still require the protection ring? That would be rather pointless... unless this boot disc really does have the behavior of canceling the check while the power is on.

I think this would be interesting also. If there is indeed some "magic code" that can be sent to the CD controller to disable the need for the security check, it might be possible to put it into AR firmware...

Considering how locked up the protection is overall, though., I doubt it's that easy - if it is indeed accomplished by sending a "magic code" to the CD controller, it probably won't accept it without already having the check successfully done (since the boot disc presumably has the security signature, otherwise it wouldn't boot), making the whole exercise fairly useless.

is there a security ring around the outside of this black disc?

if so then you are going to have the same problem as with normal saturn discs, a normal cdrom/cdr drive cannot read anything on that area of the disc, so dumping it would be pretty useless

on the other hand if there isnt one you could possibly make some use of a copy of it

well, technically, you could use it via the swap, and then use CDRs until you turn off the saturn next time... but that's only useful if you play several games in a row.

thats true

however if the disc was dumped so more people could look at it maybe they could find a way to use this to the advantage of more people?

Ripping this CD certainly can't hurt ;)

If you can say, which developer was it from?

it wouldn't make any difference which developer it was from as far as this disc goes, as any third party developer would have received the same disc

it could get the developer in trouble possibly though

It certainly couldn't hurt, so why not? I'm just really curious to see the way the image and IP are set up... and maybe disasm the 1st read program to see just what's going on...

put disc in drive, hit write to image file....check two boxes, set max speed, name it boot and you'll end up with somthin like this:

boot.ccd

boot.img

boot.sub

image will b largest, sub will be about 30megs, and ccd will be 3-10megs...should only take about 3minutes for a full disc, but sizes will be much smaller probably cause boot cd shouldnt have much data on it
