Hi,
I'm trying to find the pointer adress of the ammount of bullets I have in "Postal 2 - Apocalypse Weekend". The adress changes every time I die so... yeah...
What I have done is scanned for the amount of bullets I have, then find out what writes to the adress

it is : 1013EFAE mov [ebx], eax

so I hex scan for what ebx says (0873FE74) but nothing comes up?

edit: if I replace the code with something that does nothing, I can shoot as many bullets as I want but for some reason the dogs don't die...

Look for other codes too which are accessing to address and if there is some code like [eax+44] or similar when not only a register is between the brackets, then use that code. Or just check the register values and probably You will find which one is a the base address (the register which is close to Your address but not entirely the same).

What he found was a shared instruction "if it is the right one", notice he said the dogs wont die if replaced with code that does nothing.

I would do like Geri says, try it again to see if you land back at the same one, if you do then look at whats around this instruction instead of bothering with that instruction. If your lucky you may even see something as simple as mov [eax],5 and 5 being the number of bullets of the gun.

It is not a problem if He is using a shared code when searching for pointers, He needs the base address only. If He want to use code injection, then it will be a small problem unless He can analyze the structures.

And I forgot to say, if You are stuck, use the pointer scanner.

the pointer scanner takes years to complete...

Yeah, sometimes. And code injection is a better solution anyway.

I don't really know how to edit codes and inject n stuff...

anyway the real solution here is to not die... but I can't find anything to do with the health's amount.

Well You have about 2 options with CE.

Pointer
Code injection

You will need to learn at least one of them to deal with DMA.
