Editing Ziggy's mod

[Delano762]

So basically I need to make my own version of that mod which combines features from both hardcore and casual versions. My problems regard this:

1. Free weapon unlocks from dropped weapons

2. Attachments to several enemy weapons.

3. Amount of ammo in your gun's clip isn't shown on the HUD.

 

Question is: Which files are responsible for these things?

 

I can probably figure out how to tweak them myself, but only if I know which files I'm supposed to edit. In case you're wondering, I already know how to pack and unpack patch.dat archives.
