? for coders adding hacks to a dll

Ok, I have no experience with coding dll hacks, but I did download a .dll splitter, anyways, I have a working .dll hack but the only thing it has is Wall hack , my ? is, if I have a working .dll hack, how hard would it be to add no recoil, no spread, and what would i have to do, or download, i kow we all hate nubs, but if I got this I would be able to make and share more hacks in the future.
p.s this game is not CA, so the addy finding procedures migt be diff, but I need the main overview, and if theres already a tut on this, post link, and sorry, but I couldnt find it Thanks in AdVaNcE ~HeyD

I doubt you can.
