Lol... I just realized what a silly question that was because the answer was on the front page.

Ooops. Sorry about that.

resigning simply (because this is the most of my understanding) takes whatever file that has been modifed and creates a new string of something in the file that is identical to the xbox's method of creating a file. so when put on the xbox it sees it as a perfectly valid file and not modified. Thus resigning lets modified files be run on a retail 360. Again this is only the amount i know and has very little specifics sorry about that.

EDIT: fail

No not really.

was it the old bubble shield (rolling one) ? I did that already but the most I could get would be a choppy but high quality video

Note: Asset extraction, prohibited from the beta, is now permitted. Feel free to post renders, tools, etc.

Any chance of those being released?

This is what makes me mad at times. Seems like half the community gets mad at people. (check all the locked topic) because they ask something that is completely irrelevant. Saying, "No not really" doesn't help anyone here at all. Maybe if someone just came out and gave 2 sentences of the anwser they wanted instead of bashing them with No's and your wrong. You could help them. If were all a community helping each other. When does "No Not really" come in. That's what I thought resigning did. So guess I was wrong, Care to explain exactly what it does then?

No, not really

Without going into detail, Halo 3 just validates portions (via hashing) of the cache files then compares the signature (via RSA) of those validation results against the expected hash data and it's signature stored in the cache header.
Without the private key (for the RSA algorithm) bungie used in the first place, you won't be able to modify, then resign the hash results and it's signature that Halo 3 will check for, thus you will never be able to modify the cache files unless you have a xbox capable of running unsigned code.

Nor will you ever be able to figure out the key used, using today's or even tomorrow's tech and expect the results in this millennium. I don't know why people think they can and just ignore that fact and waste their time developing a pointless application for trying...

Not likely. Even before it was released, people were stealing tools, decompiling them, circumventing protections, etc. As with most, people proved themselves irresponsible with what they had, ruining it for everyone. Plus, for the tool I had in mind when I wrote that, it would require going back and modifying the program to make it suitable for release, which would not be desirable. One would want to work on retail, not go back and mess with beta stuff anymore.

Has any progress been made recently on asset extraction for retail?

You were seriously directing that at me weren't you.
