I am searching for the ammo values using wiird. I found 10 that all seem to be for ammo. Do you think this is a mistake or should I just pick one value to use in the code?
It is likely that one or two of them deal with ammo itself, whilst most of the others are somehow linked to the graphics representing the ammo. Trial and error is generally the simplest solution - poke each value with a higher number and see if it changes your actual ammo or just what the graphics suggests it is.
