You cannot get 007/SC/Mech to run on the 360 if they actually are the editions that have the flaw in them. I did try 2 different versions of Splinter Cell 1 on the XBOX and the one for the exploit wouldn't boot. to make sure i borrowed another copy of that same one and it still wouldn't boot compared to the platinum, that DID boot on the 360.
I don't think you know much about the exploits do you.
I have over 70 copies of 007/SC/MA right here next to me right now and the only ones that are patched for the buffer-overflow are Microsoft's very own MechAssault game (patched = version 008, non-patched = version 001).
So if you're saying that Splinter Cell 1 Platinum works fine then I have about 30 copies to choose from!
