i have this chunk of memory and i think it's using stack, is there any way to find a static pointer? i tried finding esi, found 1 pointer, but not green.

tx, i tried to post as url+pic, but said i cannot post url. Crying or Very sad

i'm trying to search a value inside this game, i'm able to find the address n freeze it, but it chg evtime the game is restarted. it adds stat to my char in the game.

the final value is at ecx, being thrown to a pointer. i can use code inject, but half the time it crash the game.

umm, which code? i can find the pointer from esi, but it's not the final one. i believe it's a multi-level pointer, not sure if stack hv any implication on it.

Test all of them, one at a time, starting at the top.

Chances are it's the smallest address, the very first result.
