Gibbed's mod has got me really excited and I'd love to try modding DX:HR, but I have no idea where to start. I'm not even sure what the patch0 file is, let alone how to start tinkering with it. In the past I've played with tools like GECK/FOSE for Fallout, but I know that this is entirely different...essentially hacking rather than developing.
Is there any information about how Gibbed was able to do this (outside of SA) or even some more basic info about how to get started looking at the game files?
BTW: Thanks for the MOD and for posting it here too!
