so I know there is a chip that mods systems. that is simple. but on halo2...I hear people saying "that dude is modding" and things like that. i thought you can't get online with chips on your system so I am assuming they are doing something else. I looked all over the internet and I can't find a thing about it. when I ask people, they don't really tell me. basically, I want to know what halo 2 modding is. I don't want to know how it is done...just wtf it is.
