It's now possible to back up dc games withs a cd/dvd reader/burner !!!

[--=FamilyGuy=--]

Check this out : http://homepage.ntlworld.com/menace-59/gd-rom_stuff/

It really works : I already backed up my tony hawk's 2 game (changing the songs :P ) and Toys Commander.

I use a LITE-ON LTD-165H DVD-ROM bought on ebay for 4$ !!!

It's my dream that came true !!!

I was wanting to share it with you!!

I put this cd in my dismantled drive, I wait for it to load, I swap with a gd-r, I open with isobuster, then I'll see a generic File system ( not the gd files) so then I open the isobuster's options and check show both lilttle indian and big indian ( only to make the gd rescanned) the true gd filesystem now apear like magic !!! (I then uncheck the lil' + big Indian flag)

I can extract everyfile directly from the gd-r directly this way using isobuster and I can create a sort.txt

I tested it with chancast but it don't work.

That's what it looks like with the sega magazine feb 2000:



I just wanna share this interesting discovery with you.

Bought the coder's cable years ago and have backed up all my games (well, except the ones which were too big like Skies or had complicated protections like Sega Extreme Sports).

I'm so glad I've got my BBA some years ago.... (altough I mainly used it for Dreamcast devving)

I guess that those guides will work, but I think its a real pain to rip GD's that way... I would like to see comments about that method.

[Darkfalz]

So Bucanero, still no simple tool for reading/writing DCI files to and from VMUs via dc-load?

[--=FamilyGuy=--]

It's fast ( as fast as your dvd-reader can read) an easy everything you must know is how to use cdrwin (or isobuster) and how to remove the cap from your dvd-drive (cd-drive works too).

To downsample things you can use many tools that are free to download on the net or that are not free as Sega Movie Creator.

You can also change the songs in a game :P or add your name to the credits !!

It's easy and Dreamcast -=Worth=- the time you'll spend backing up your game to play it with enchanced or modified songs and\or videos.

This technique also work with multiple cdda tracks (CHUCHU ROCKET) and you can burn audio\data AND data\data SeflBooting cd or image using the tools you can find on the site.

So far I ripped sucessfully all the games that i tried to rip :

Toys Commander
Sonic Adventure
Tony Hawk's pro skater 2
Trickstyle
Shenmue ( With -=>MANY<=- downsampling)
And I'm working on Bleemcast GT2 but it's all mesed up with data passed the lead out of the disc.( That's the weirdest thing in the world after the women's way to think :P)

Sorry for my BAD grammar in English because I'm a Québécois et fier de l'être !!!

Vive le Québec Libre !!

[djgarf]

bleemcast had extremly good custom protection and i have yet to see anyone do a successful rip from a original bleemcast disk

[--=FamilyGuy=--]

That's true but with a lil' swap trick ( almost the same as in the tut on the site I posted a link) I notice that there was ,passed the lead out of the disc, 5 little Cluster (LBA) with this written on: bleem , maybe is this the damn bleem copy protection !! LOL The Dreamcast don't even care about cd leadout or even leadin it search for a custom TOC at 45000 LBA or for an audio disc (utopia boot method[mil-cd]) so on bleemcast disc the program can do a check if it's written bleem at lba "X" (where X is after the leadout) because the DC can check from 1 LBA to 549 500 LBA (122min a normal gd-rom) without bothering about the normal formatted TOC (lead in/out)

Bleem also used a F*ked up cd format like Joliet but that allow file with Weird name (there's a file that looks to have no name but that have in fact an one character name that look absolutely like a normal space)

By the way that's speculation.

I wish it helped you and dont forgot to check the site that I posted a link to !! it's damn HOT!!

-=FamilyGuy=-

[lenselijer]

very good information --=FamilyGuy=--

Bleemcast is indeed a MIL-CD, they say that on the cover: "Runs on any MIL-CD compatible Dreamcast".

So you need to hack the bleem disc to disable the LBA checks

[--=FamilyGuy=--]

Check this out !! this is where the bad sector gaps are on the bleemcast gt2 disc. The biggest part of the disc is written passed the lead out and i think that the bad sector must be bad for the disc to boot perfectly.

If anyone know a program ( a free one plz) that allow me to write on a cdrom at any starting lba to any endind lba i'll be able to reproduce the bad sector.( I need to write things from (example) lba 11702 to 25145 in the second session, to dont write anything from lba 25146 to 25264 and to write things from 25265 to ... (etc) so, I think the bad sectors will be reprodeced.

The log is writted from the bottom to the top.

[--=FamilyGuy=--]

Ok so I have news for you.

I've been able using a swap method to write a second session at 11702 (it can be any other lba) -=WITHOUT=- writing a first session. Then I wrote the first session but only from sector 0 to 301 ( the drive was thinking that the disc was Empty |Without the 2nd session| so from sector 302 to 11701 it's bad sector !!!)

My new computer with WinXp pro and a Lg dvd reader read it as a single session cd ( only the 0-301 session) even with isobuster.

My old computausaurus PII 350mhz with a Ltd 165h dvdreader read it, on isobuster, as a 2 session cd (the second session being open) and with this «TOC»

1st session : 0 to 301
2de session : 11702 to 335498
(so 302 to 11701 is still blank)

But It report last session to be BAD SECTORS only the Toc of the session is readable, NOT THE FILES.

and on this same computer with alcohol it give me this:

Disc Type: CD-XA
Recordable: yes Volume Name: -=FamilyGuy=-
Session: 1
Track: 1
Free space: 00347202 678.1 MB (077:09:27
Used Space: -0000001 9408.00 GB (36933:10:45)

Session|Track|_____Mode______|__Adress___|_Number of sector_|
01____|01___|Mode 2 Form 1___|00000000___|00000302 (693 KB)

02____|02___|_______________|___________|_________ _______|

(this is a translation from french)

so... weird eu!!

That's not all !!

With my computausaurus with cdrwin it only see the 1st session(0-301)

Using an emulator for the dreamcast (nesterdc) to browse my disc It read only the first session (1-301).

THIS DISC IS "UNBACKUPABLE"

So I think that if I write my Bleemcast Disc until the so called lead out (the one the computer use) then I put a disc written in an openlast session that end at the same lba that my other disc then star to write the 2de session with a countdownbefore it start(cdrecord:10sec) and I swap the disc for my finalized one before it end , it'll write it passed the TOC. I think I must do this at EVERY F***in' Bad sector "area"(as in my last reply).

Gonna try this ... it'll be long...

[--=FamilyGuy=--]

So... I failed to do this one... I'll probably NEVER do a working realeasable iso of this bleemcast disc, but, one day,before i die, even if I must buy a custom pressburner/gd-writer, I'll copy this disc !!!

Randy Linden, You're the Damn GOD of the Dreamcast

All my respect go to you, because you've done what SEGA never been able to do with this wonderful console, an "unbackupable" disc !!!! even if you where using in fact a backup-like way to boot it

-=FamilyGuy=-

[--=FamilyGuy=--]

But at least... now we know where are the bad seectors on the bleemcast disc :P

No wonder why some of the best groups in the "DC scene" couldn't hack those bleemcast discs...

So the guys at Bleem! indeed made a good protection scheme.

[--=FamilyGuy=--]

Yes, It's true , they made and wonderful job... Some game developper should follow their example :P

If I was a guy at M$ I would have bought the right on this protection scheme many years ago !!!!!

Even if it seems to waste some disc space ...

UPDATE:

I've been able to create a cd with the same TOC that a real GD-Rom

SESSION 01
TRACK 01 MODE1/2352
INDEX 01 00:00:00
REM MSF: 00:00:00 = LBA: 0
TRACK 02 AUDIO
INDEX 01 00:13:22
REM MSF: 00:13:22 = LBA: 997

SESSION 02
TRACK 03 MODE1/2352
INDEX 01 10:00:00
REM MSF: 10:00:00 = LBA: 45000

Lead out : 549150
------------------

I put this cd in my dismantled drive, I wait for it to load, I swap with a gd-r, I open with isobuster, then I'll see a generic File system ( not the gd files) so then I open the isobuster's options and check show both lilttle indian and big indian ( only to make the gd rescanned) the true gd filesystem now apear like magic !!! (I then uncheck the lil' + big Indian flag)

I can extract everyfile directly from the gd-r directly this way using isobuster and I can create a sort.txt

I tested it with chancast but it don't work.
