mark the address in autohack (one that it found) right click right address and choose autohack I dont member if there was 1 or more addresses but.just freeze one and find out the right one.
if u shot like 10 bullets and RELOADED then search for 52.keep doing that. Then shoot some bullets and RELOAD!!! if u dont reload then value wont dec. 50 in one and 12 in other then u search for 62. run game in window because u cant minimize it.
it simply takes out command that tells game to dec.
You have to use autohack to get inf ammo for all. Search for value u have in inventory screen.
