I could actually do this, I'm experienced with IDA. I'll look into it when I get off work.. But why hasn't this been done, or has it been done but no one released it? You seem to know a thing or two, have you done this?
No I have not done this. I have too many other projects on the go but I would like to see this game and any other Activision game get ruined by hackers so I watch the Destiny forums.
As for why no one has done it yet I don't know. There seems to be a lack of interest, possibly because the game sux. From the quick look I took the DW methods are not as complex as PB to get around so I expect anyone who puts some time into it will solve it.
When I am freed up from my other projects I want to create FLIRT files for the Demonware libs but I can't see this happening for a couple of months.
