 Posted: Thu Mar 23, 2023 12:31 am Post subject: How can I add pointer which has multiple registers? |
 |
|
I found below opcode which very frequently access to an address which I aimed at.
AI5WIN.exe+DCE7 - 8B 80 E8000000 - mov eax,[eax+000000E8]
AI5WIN.exe+DCED - 8B 48 0C - mov ecx,[eax+0C]
AI5WIN.exe+DCF0 - 8B 51 04 - mov edx,[ecx+04]
AI5WIN.exe+DCF3 - 8B 84 02 64B50400 - mov eax,[edx+eax+0004B564]
EAX=083CC088
EDX=0002299C
But the opcode(AI5WIN.exe+DCF3) ,which very frequently access to aimed address, seems that It has two register(edx,eax) which originally consist of
add calculation and multiple dereference of eax register like below code.
| Code: |
mov "altered eax",[ [[[eax+000000E8]+0C]+04]+[eax+000000E8]+0004B564 ]
|
Is it possible to point(dereference) to an aimed address in cheat engine with add calculation of edx and eax register which seems to consist of multiple pointer ?

CE won't say no, but first you need the initial eax, the one that will be added to the offset of E8 (ie: the base pointer where it is coming from), that will then be used to calculate the rest of the pointer's addresses in order to reach your final target address
| Code: | | mov eax,[eax+000000E8] |

Is it impossible to add each of two base address, which is dereferenced by eax register, instead of to add offset by clicking the add address manually button in order to create pointer in cheat engine?

easier to do a code injection that stores the address somewhere
