 Posted: Thu Jan 31, 2019 4:08 pm Post subject: AoB Injection Script Not working |
 |
|
Trying to use a template to create an AOB Injection script, I got the following error:
| Quote: | | ERROR: Could not find unique AOB, tried code "8B 4D 08 89 48 2C" |
Searching for the error, I found this thread where Twistedfate says to select more instructions to get a unique array of bytes. So, I added two more instructions which adds "8B E5 5D" to the array. However, the script will not activate. Does that mean that the array is still not unique & I need to add more instructions? Or, have I made a mistake in my script?
| Code: | [ENABLE]
aobscanmodule(aobAutoGameOver,MMU.exe,8B 4D 08 89 48 2C 8B E5 5D) // should be unique
alloc(newmem,$1000)
label(code)
label(return)
newmem:
code:
//mov ecx,[ebp+08]
mov ecx,(int)0
mov [eax+2C],ecx
mov esp,ebp
pop ebp
jmp return
aobAutoGameOver+BB56F0:
jmp newmem
nop
return:
registersymbol(aobAutoGameOver)
[DISABLE]
aobAutoGameOver+BB56F0:
db 8B 4D 08 89 48 2C 8B E5 5D
unregistersymbol(aobAutoGameOver)
dealloc(newmem) |
A screenshot of the memory view is attached.

It might be (likely if the script won't activate). I mean did you (at normal scan screen), select "Value Type" select "Array of byte", added the ... AOB, in this case "8B 4D 08 89 48 2C 8B E5 5D" (without "") and it just returns 1 result?
Anyway what is clearly wrong: remove the offset (+BB56F0) from the TWO aobAutoGameOver lines (at enable/disable). This is automatically generated if it can't find a unique entry point itself. So it tries to jump to module+offset.
If this does have anything to with activation depends on if the aobscan does find a result or not and if, what the address+offset point to and if you got full access to it.

Ah, okay. I didn't know how to do that. No, it is not unique.

Thank you.
That solves my problems in the scope of this thread.
Edit: To search for a unique array, from the Memory Viewer I selected Search -> Find memory. Is that what you meant by "normal scan screen"?
Edit: Oh! Sorry. I realize what you are talking about. The main window....
Edit: Attached is a screenshot of the scan showing that the AOB is not unique. Thank you again salumor.

To make it unique add more results. So after 5D add C2 to CE scan, click Next Scan ... find your way to a unique AOB.
OPTIONAL: You may also want to use wildcards on offsets and co if you want to make it compatible with updates. Though you'd also need to change your code then to read that. Take a look at https://forum.cheatengine.org/viewtopic.php?t=609288 a very typical aob might look like f.e.: 48 8B ?? 48 63 ?? ????0000 3B C6 0F84 ????0000 4C (and that still expects the registers to not change but .... keep it simple)
In your case maybe: 8B 4D ?? 89 48 ?? 8B E5 5D C2 ???? CC

because of:
| Code: | | aobAutoGameOver+BB56F0 |
and even if it worked, it will crash your game. (because you have many mistakes)
anyhow, this should work:
| Code: | [ENABLE]
aobscanmodule(aobAutoGameOver,MMU.exe,89 4D FC 8B 4D FC E8 ?? ?? ?? ?? 8B 45 FC 8B 4D 08 89 48 2C 8B E5 5D C2 04 00 CC CC 55 8B EC 51) // should be unique
// aobscanregion(aobAutoGameOver,"MMU.exe"+4000,"MMU.exe"+4FFF,89 4D FC 8B 4D FC E8 ?? ?? ?? ?? 8B 45 FC 8B 4D 08 89 48 2C 8B E5 5D C2 04 00 CC CC 55 8B EC 51)
{
if aobscanmodule failed, then comment it and uncomment aobscanregion .. which should not fail.
}
alloc(newmem,$100)
label(code)
label(return)
newmem:
mov [ebp+08],0
code:
mov eax,[ebp-04]
mov ecx,[ebp+08]
jmp return
aobAutoGameOver+0B:
jmp newmem
nop
return:
registersymbol(aobAutoGameOver)
[DISABLE]
aobAutoGameOver+0B:
db 8B 45 FC 8B 4D 08
unregistersymbol(aobAutoGameOver)
dealloc(newmem) |
