Could someone enlighten me about why do we need Kreon drives for dumping the Xbox discs and what's wrong with all the 'regular' drives? "Invisible" Xbox partition is the only problem?

It's a DVD-Video disc that just happens to have some Xbox compatible demo files on them, so DVD-Video is the primary format.

I doubt the demos are just lying in the VIDEO_TS folder. Also, any Xbox disc has the DVD-Video section part, that doesn't mean all the Xbox discs should be put into the DVD-Video section.

Maybe there are any optical drives that can be hacked/modified into reading UMD discs? tongue

Has anyone tried to insert them into the PC drive? I've heard the ideas but were there any real experiments?

https://www.ecma-international.org/publ … MA-365.pdf -- looks like a normal DVD structure? Same sector format, same lead-in sector format, no BCA, are you sure they aren't readable? The centre hole is 11mm for UMDs vs 15mm for CDs/DVDs, so you either need a custom spindle or to carefully enlarge the hole before inserting it into the drive.

Also I got a reply back from the Splinter Cell demo guy. He says hes interested in dumping and submitting it. I linked him to all the appropriate areas. He says he thinks he might still have his old 0800 drive.

Nice! Browsing the assemblergames forum, there's another guy with Armed & Dangerous Xbox Playable Demo (which is a DVD-R release, either a copy or intended for debug consoles), a guy with 4 japanese demos (we miss 3 of them), a few guys with unreleased betas (like Fuel), a few guys with Debug versions of certain games and I've noticed this thread - https://assemblergames.com/threads/requ … vds.63263/

Has anyone tried to dump those DVD/Demo combos? I know one of our dumpers has that disc with the Battlefront II demo.

0 08888 99187 8 and 0 08888 59261 7 barcodes belong to US/Canada, from this point of view both demos are (USA). And to show the DMI.bin region - maybe worth to ask iR0b0t to add some special filter code for the comments section, similar to "Internal Serial" for PSX discs?

For the Splinter Cell demo, I messaged the OP about it on Assembler Games. We'll see if he still has the disc / is willing to help out.

Interesting, that this demo goes ingame in Cxbx-R, while the retail one doesn't.

How are you deciding based on ringcodes that they are likely only USA releases. By the "-US" in the mastering code? How do you distinguish regions by barcode? Do you have a reference that can be read / used?

I've meant http://redump.org/disc/13488/ - "0 20626 72381 7, 3 348542 199309, 3 348542 199316" - the first barcode belongs to US, other two belong to France, so it looks more like (USA, Europe) rather than (World), also it wasn't even released in Japan, according to Wiki - https://en.wikipedia.org/wiki/List_of_Xbox_games

To answer your question no I have never seen that before. I thought I was going crazy at first because the photobucket web page was cutting off the bottom half of the image obscuring the Splinter Cell sleeve. I had to right click > view image to see anything useful.

Yes, quite confusing, I guess, but the region in db shows the region of the release, not the internal region encoding. Like, http://redump.org/disc/31187/ is JTUBKAEL (Japan, Taiwan, USA, Brazil, Korea, Asia, Europe, Latin America), so it's "World" from the region-lock's point of view, but that disc with that ringcode was only sold in Europe, so it's (Europe), not (World).

h0lylag wrote:

So I think they would all need to be fixed?

Most likely (unless the same disc of the same version was really released in all 3 regions, it is possible). Should be more or less safe to judge by the barcodes, I think.

Btw, have you ever seen the Splinter Cell's demo packed the similar way? I can't find any good photos, only this small one: http://i494.photobucket.com/albums/rr30 … IM0923.jpg

While I agree these should be called Exhibition Volume X (Demo Disc/Demo Disc for Xbox is more like 'explanation' there rather than a part of the title and even appears in different places on the side of the box vs the front cover), I don't understand the reason to call them "Xbox Exhibition (I only see the normal Xbox logo on them, but following this logic you need to add "Xbox" to all the titles).

But you still need to fill all those fields by yourself via some offline form. What's the real difference?

Images? CD-R copies? 'Original' CD-Rs (PlayStation or publisher-branded)?

DIC should report if D8 support is missing. Or set the D8 read command in EAC and try to dump something (EAC => Drive Options => Drive => Drive read command => Read command D8).

A fresh example of incorrect subchannels fixing: https://mega.nz/#!2CwkQRBL!9-ygJ4lzW3nK … 8hl6o_WHLk

As a result, it added "CATALOG =0=0=0=0=0=00" (incorrect fix of 188294) and "INDEX 02 00:05:20" (incorrect fix of 188295). The subchannel fixing system needs a rework, the cues aren't trustable.

Buggy drive with incorrect C2 errors handling, then. That's why EAC has a built-in testing for the C2 errors support.

I confirmed getting the similar data. Scrambled data is almost all 0x59 or 0xa8.
If this is really data of the ring

- ring's main channel data, when unscrambled, reveals Sub-Header: 00 00 28 00 and EDC set to 0
Sub-Header Submode byte 28h translates into:
00101000b -> Data = 1, Form = 1 (Form2)
- when left scrambled, main channel user data form patterns consisting of A8h and 59h bytes.
those bytes yield somewhat opposite pit/land sequences:
59h producing long continuous runs, A8h - frequent changes
- when interleaved those patterns form visible inscription: 59h being background and A8h data,
with each revolution taking up exactly 21 sector.

does burned cd-r with this data works in sega saturn without hacking?

The ring should be burned after lead-out, you can't burn session 1 + lead-out + ring properly with the normal CD-R recorder. You can hack the TOC, so the ring would be included into the session 1 or burned as session 2, but that would be wrong for unmodded Saturn. But you can get the same ring text graphics smile

I've also read that Saturn discs may have some wobble-encoded data near the ring, so it's possible that ring data only isn't enough to beat the protection.

I am worried as I don't know how easy this virus can spread, and if it spreads easy, which I am preying it doesn't how easy can the virus pass from one disc to another. That's the real worry.

Why not to find some unneeded CD and put it together with the "virused CD" somewhere? Though, these look more like surface scratches to me.

Even if it is so, it is enough in 90 sec to preserve lead-out. If there are some data except empty and shifted data in lead-out, it's not already lead-out.

The key point is to preserve as much data as possible.

sarami wrote:

I'll refer to it.

Basically, that's how the subdump "-fix" option works. For each of the P, R, S, T, U, V, W channels you just need to detect the padding byte for the current sector (if more than 6 bytes are 0x00 - the padding byte is 0x00, if more than 6 bytes are 0xFF - the padding byte is 0xFF), then do a bit compare of the current sector against 000000000000000000000000 or FFFFFFFFFFFFFFFFFFFFFFFF or any other variant, if exists. If a number of mismatching bits is <=FixLevel: fix them, if >FixLevel: reread or skip. If the padding byte can't be detected - reread or skip, for R-W channels that could mean CD+G data.

sarami wrote:

Saturn ring, I don't know the detail. At least, this ring can't be read unless someone hacks sega saturn.

They can be read on any drive that supports swapping, similar to DC rings smile

You can even hack the TOC and burn them on CD-R and you will get the proper burned ring with the same SEGA text.

Maybe they mean the multisessional discs? And what is PMCD? All the sectors after the user area are marked as 0xAA in the subs and are either empty data or empty audio sectors, they go upto the very end of the disc (except the special cases with the data shifted into the lead-out area, Saturn rings that go after the leadout, etc.)
