Hi all.
I have got this prebuilt trainer for GoW,and i am putting up its screen shot.
I am currently trying to develop my own trainer for the same game,but am clueless on how to proceed.
Could some of the more experienced ppl here explain to me how these features of the trainer must have been developed?....So,this shall give me an idea as to how to proceed with this and other games,since these can be applied in most FPS-s.


Also,i think this sort of discussion shall help many newbies such as myself.

btw,i have numbered the features so as to make the discussion easier.

I am also going to do a similar exercise for the trainer of Burnout Paradise,with the same intention of building my game hacking skills further(if this goes well.)
