I installed Windows Vista on my machine, and I noticed that Media Center comes with a file called "XboxMCX-V.XEX". Someone mentioned that this file is sent to the Xbox 360 when the user activates the Media Center Extender option. Has there been any research into this file? Since MS did not just include it with the Xbox 360, I would assume that they will update it in the future, so they can't just compare a checksum of the file sent to the 360, because it would change with each new version. Is it possible to swap this file with another signed XEX? I don't have an Xbox 360 yet, so I'm not able to check.
For those who want to find the file, it is installed at :
Along with a signature that guards against tampering, the XEX header also includes a media flag
. This flag limits the source from which the executable will be executed. IIRC the Media Centre XEXs have a unique combination of media flags not present on any other XEX. Presumably they permit the unique network delivery method and execution of the MC XEX.This post has been edited by PedrosPad: Jun 14 2006, 01:18 PM
