ok when the update xex file have no media check... it seems possible that the file structure allowed to run from any medium, right? and the programmer put a media check in when he want, rigth too?
its same like a pc game with with any cd protection, it seems harder, but its on same way.
any good dissasembler can patch normal exe files, so they dont do a media check... why its not possible for an xex file? theoreticly it is possible or not?
now the problem is (i think) that the xex seems encrypted right? wich depends on key from xbox, we dont ever found out. i will confirm this in my mind, to media like a dvd, which stills check the checksum too. but how i could be possible for hdd? i couldnt be the same secure, cause the hdds never have the same checksum.
my english is not well enough to give more opinion details... but i think ms give first time the possiblities that you can play stuff from a hard drive... so they have to be holes with the xex file.
You're very confused with this post. The protection doesn't seem "harder" on xbox than it does on pc. It can easily be removed. It's just that once you remove the media check you throw the checksum off and invalidate the signature.
Why is it that you want to reinvent the wheel? Why you guys NOT listen to reason? We all want to circumvent the security and if we didn't know for sure these were invalid options we would be excited and try them. The problem is, they have already been tried and came up empty.
The definition of insane is to do the same thing over and over but expect a different result.
(You mentioned that a xex could not have a checksum while on hdd because hdds all have different checksums. This is where you are confused and to a certain extent I am too. The actual checksum is no problem because if the xex is simply an executable the checksum will only be of the executable. If the xex is an archive the executable is still contained within the archive and that would have a checksum... [here is where I'm confused] but would the archive have the checksum? )
What I'm saying is, either way it's possible since the checksum is not of the physical media but it is of the data on the media... specifically a xex. I just don't yet understand exactly how it's done.
