Re: decrypting bgt stuff?
@21, first, your not proving anything and making very wild assumptions about a lot of things. Your assuming that the key can be easily determined by picking random offsets in the core dump and just scanning from there. Sorry, buddy, not how that works. Your also making assumptions about key lengths.
Really, your just making claims that are very difficult to believe. Your making a claim that if I load a 500 MB file that's a BGT program, sounds and all, that I can just locate the decryption key in about a minute or so. That is not feasible. In a 500 MB program, there are 524288000 offsets. Let's assume that the base address is our starting offset. The base address is 0x400000. That would mean offsets 0x400000 to 0x1f800000. Since the game is loaded in RAM by the time you generate the dump, you can't exclude anything. I'm sorry but unless you actually provide code and provide a working PoC, I find your claim impossible to believe. I'll stick with the tried and true method of debugging the application to cut sounds and other pack data out of a BGT executable, which has been proven to work time and time again.
