My suspicion related to Sentinel was due to the change in attitude about "needs of the majority rules". I saw it again a couple of pages back....a small minority might hack them so that means the majority can't use them.
I'm sorry, but this stubborn "onoes, it's possible to hack them so someone will!" fearmongering is only good for one thing: making me laugh. Capability does not equal motive.
I'll spell it out for you:
You have no idea what is used the generate the checksum. You have no idea how it's processed before generating the checksum. You have no idea what is added to it before generating the checksum. You have no idea what formula is used to generate the checksum. Nobody is capable of generating a valid checksum for any S+ file under those circumstances (and if someone did, they would have far more lucrative uses for the basis for such a capability).
That
only people who would have the know-how as to how the S+ checksums are produced amounts to GuyPerfect (aka: the man who developed S+ to begin with) and maybe a handful of other people who may have had access to S+ source code (Codewalker, perhaps, and I'm not sure anyone else did).
Sorry, but insisting that you expect them to muck with their own Sentinel exports just to gain an unfair advantage is, frankly, insane.
