Set up MHS/CE to make these hotkeys:
Increased Value -> +
Decreased Value -> -
Load up CA and go into a game. Tick 'Fast Scan'.
1.) Start a Unknown Initial Value
2.) Shoot, while shooting press the + sign.
3.) Stop Shooting, when reset press - sign.
Rinse and repeat.
Once you start narrowing the values down to around >50 look for values that are 0.
I got around (5) 0 values. Freeze all of these 0 values and check in-game when shooting that the bullets only go up-down.
There should be a green address that is at 0 as well. That address seems to do most of the left-right while a few others provide more alignment. (Atleast I got that one).
