i dunno about everywhere else, but xbox games are about to be hacked and backups will become available soon (around me)
i don’t know if they’ll be simialr to DC/PS2/PSX backups but ill give more info when i get it.
Before now, xbox games have been uncopyable …
me is curious
by the way … did you cross posted this ? for a minuted it looked like it 
no i haven’t - while ago i posted about is there such things as xbox backups, but now i got new info and that thread is no oooold.
Ill give more info when i recieve it 
btw, u got an x box.
no , but i’m interested

They still are, and I bet they will still be after summer

No, it’s a matter of time. I 'd find out bbut i am only a week away from my Xams, so i dont have the time[i need to go to a different city]
Ill post the info when i get it
Do you need mod chips or a boot disc for the xbox? I didnt know they had those yet?
since yesterday all xbox games are released, some are very big : halo around 3 giga, others like Shrek only 300 MB
I give you the information written in the nfo
We tested this game on a developer XBOX, and it works. Since there is no mod chip yet, we have no idea if this release will work on retail XBOXes when/if a mod comes out. However, now that there is a release,a modchip developer will be inclined to get our releases to work, so we think a future mod will work with this release.
If a game is small enough to be burned to a CD, you can burn it to either a CD or DVD, at your option, using the same ISO file.
The Xbox does not use media checks like the PS2.
When burning to a CD, if your CD burning program has an option,
choose “MODE1/2048”, exactly as if you were burning a PC CD-ROM.
We recommend PrimoDVD for burning Xbox for both CD and DVD, but all CD writing software besides Clone CD should work fine.
From our experience, the retail Xbox can only read DVD-RW’s
and CD-RW’s, so if you want to be sure that these will work
with a future mod, we recommend burning them to Rewritable
discs. We have heard reports of the retail Xbox reading some
types of DVD-R discs, but we have been unable to verify this.

Whats a developer xbox?

Why not cloncd?
Who is “we”?
Cheers
I believe that a developer X-Box is an X-Box that does not check for Microsofts digital signiture on the game (and before anyone asks, the signniture can’t be forged without a super-computer and a few million years. It’s rumored to be a 768-bit RSA key, if you know what that means)

Wow, nice “release”
shuebhussain:
An xbox dvd cannot be obtained by a burning
process, so to get a real copy (which runs without
modifying the console) you need the money and
equipment of a small company. So it’s not
impossible, but your friends will have to sell a lot
of ‘backups’ to get their money back. Good luck
for your exams, and keep us informed
About Microsoft Signature - okay we can’t forge it, can’t we just copy it?

You seem not to be on par with current technology. You don’t even need close to a supercomputer equipment and a few million years to break RSA-768. In fact - with today’s technology and a few million dollars to spend (to build a custom factoring device) - it is even possible to break RSA-1024 within minutes.

What?
Even with Shamir’s (theoretical) twinkle device, and breaking edge factoring advances with the NFS, a 768-bit key should take at least a few months. And also note I said rumored. The Microsoft Website public key is (as of the last time I checked) is 2048 bits. This is what I bet the X-Box public key is. The millions of years estimate was provided by me, with a 2048 key, and and the 768 was provided by others. Did I not make this clear?

Hahaha, sure. Why don’t you give us an URL to
back up that crazy claim ?
Heh, of course I expected such a reaction. The “minutes” claim for 1024 is probably best case, so I was a little bit exaggerating. However, to break 1024 is feasible.
D. J. Bernstein wrote a paper about a hardware factoring device.

And finally the discussion and, more important, real life implications on the GnuPG developers list:
http://lists.gnupg.org/pipermail/gnupg-devel/2002-March/006922.html (and msgs belonging to that thread)
You might also want to look into
http://www.counterpane.com/crypto-gram-0203.html#6
for Bruce Schneiers [developer of Blowfish and Twofish] thoughts on the subject.
@SirDavidGuy:
2048 bit is - of course - a completely different beast. Although I wouldn’t say millions of years; given the past advances in computer speed aswell as factoring algorithms (plus the still possible mathematical breakthrough) I’d say 100 years at best. This is of course complete speculation.
But this is going waay off topic…
Bernstein’s paper doesn’t really apply to real-life numbers. It starts to become more and more reasonable as the keys approah infinity. His paper assumes that since it is cheaper to have n(x^1) than x^2 bits per processor, where x is number of bits used in the processor and n is the number of processors, that it is more efficient (when I say he, I don’t mean Bernstein himself. He doesn’t imply that his discovery is anything that it isn’t). However, for normal RSA sizes, it is cheaper to have 1 processor with 1 million bits of memory than 1000 processors with 1000 bits of memory, when considering the cost of networking everything. Schneier’s crypto-gram essentially says this. Bernstein also defines the processing cost as number of processors * time, which is essentially just changing the definition of effienciency.
I have to admit that I didn’t read Schneier’s crypto-gram only flew over it after it arrived (I’m subscribed to all three cited lists / newsletters). I gave it here as reference for I knew it was critic and I wanted to give ppl the chance to view the other side. Now, that you mentioned it, I read it and I have to agree with you. After Luky Green’s mail and the thread on the GnuPG list (in which no one was actually telling that the advances are not that great, only that there are other, much easier ways to invade your privacy) I was under the impression that 1024-bit keys are not secure anymore.
Hehe, I was pretty sure it was a wild interpretation
of Bernstein’s paper. If you had read it (and all
reactions about it) carefully, you would have seen
figures a bit larger than “minutes” and “a few
million dollars”. And before drawing conclusions,
you (and everybody) would better wait for the
comments of real factorization specialists (ie not
Schneier).
