hello.. First of all i have searched the forum for this topic and what i found didn't work for me so maybe I'm doing something wrong.
thats why i'm posting here now.

I have the Addresses for a specific game and I wanted to find the Byte signatures for them so i can update a trainer I made to work on another server(which is based on the same client).

Using a tutorial i found here I went to the address in memory view and
copied the Bytes(right click -> copy bytes) of the address and a few following addresses.

but these bytes always change atleast most of them everytime I reopen
the game.
so maybe I don't understand how this works. I tried using wildcards where
i thought the bytes will change but the problem is i don't know which ones will change and so on..
can anyone make this simple??
