so i am trying to make a trainer but the problem is that i need to make unlimited ammo but the weapon is fully automatic how do i make it unlimited, because i cant take one shot then go back enter the value then take another shot.
Well speaking from my minor experience here, you don't have to take just one shot.
Say you have 100 ammo, search for 100. Then go into the game and say it takes like 3 shots, then go back into Cheat Engine or whatever you're using and search again for 97.
