WOW I remember a time when someone would ask for something and get a warning and a flaming....
Now we see useful comments and good advice being spread.
cpthankey:
Get Cheat Engine
open it
run VC open your own server
attach cheat engine to the vietcong process (look in cheat engine forums for usage guide)
pick M16
you have 18 bullets
do a search for the number 18 / 4 bytes
fire one shot and search "has decreased by" value = 1
you should soon find the address for ammo.
change it, play with it, learn from it.......
I can give you some advice on memory hacking but im not a master like MrMedic, Subsky & others
hopefully you can follow the above little tut there are more than enough tutorials on the net for you to learn from
thanks
