New Shader Expirement. Options

[field2line21]

Its cool those shader editings worked on king kong demo.

How about

1. Taking a full king kong game and ripping it using a pc and xbox dvd drive IE a 616T using hotswap OR specialists dvd ulocker.

2. Editing shaders or whatever else.

3. Burning back to a dvdr.

4. Then using the hotsawp method from geuex.net where you switch the dvdr out in the xbox360 after the disc has stopped spinning at dashboard. Put the dvdr in.

5. The run the king kong dvdr game to see if shaders have changed. IE to a different color.

If they do, this proves that you can edit dvdrs since xbox360 doesnt cache game until you run it. Opening the possiblity to edit ALL TYPES of retail / full games to look for exploits or to customize them.

If this has been tried already and hasnt worked I apologize. I dont have a 360 to test on.

Once flashed, The DVD drive in the 360 should run whatever you put in it. You change the shaders, its would run those modified shaders.

Yea, I don't really know why stuff like this has resurfaced yet. When we had the Kiosk disk, everyone went nuts with trying to edit the unsigned files. Now with DVD firmware hacks, every bootable disk becomes what the Kiosk disk was... yet virtually nothing... I guess everyone is too preoccupied with piracy. A sad state of affairs

Sadly it is not posible to edit 360 isos without breaking the signature. it was only posible with the kiosk disk because the wole disk was unsigned + its media flag allowed it to be run from any type of optical media.

What are you talking about?

The disc itself isn't signed.
The firmware reports the burned DVD+R DL media as DVD-ROM. Otherwise, burned games wouldn't boot at all would they?

Editing files on the discs require either replacing them with wx360 in the image (if they are within 2048 bytes of filesize, you can probably do this without mangling the contents that follow the file) OR extracting all files from the image, and rebuilding from the ground up.

I'd have to say it more has to do with the fact that there isn't really much you can exploit with the game files, other than cheating. That and, for $2 a disc, it's pretty expensive just to test a modified file. Only someone deadset on cheating at a game, and with the time, inclination, and minor bit of knowledge to do it would bother with it. It's been done - just not widely publicized, a cheat isn't at all interesting when everybody and their pet can do it with a tutorial and a patch file.

I thought only executables were signed. If the whole disc was signed, wouldn't it take a really long time for the 360 to verify disc authenticity because it would have to hash >8GB of data every time you wanted to play a game?

So wait...

Are you saying that the kiosk disk IS unsigned code running on the 360?

And that this unsigned code is running simply because of a media flag?

[peetyboy2006]

the xex's on the kiosk disc were signed (like any other xex). The media flags tho allowed them to be played from any type of cd/dvd.

Basically we can accomplish what was accomplished with the kiosk disc, because we now have hacked firmware (which means we can run from any media) so games can be extracted, files that arent signed can be modified and it can be burnt to DL DVD and still play in the 360.

although i dont see the point in these experiments apart from cheating, but i havent looked into them fully yet.

Well one reason would be to do the hacks like they did on the first Halo... change textures & levels r play over diet connect through a tunneling Service

sorry for the dead thread revival but why is the person above me repling to a tech thread in 2008 saying games wont provide anything usefull in hacking the files..... all i say is dude King Kong Exploit
