Cheat Engine

[marco0999]

Hi,

I have created with ms detours a dll with dll injection for a game that work perfectly.

I have used this code as "template" for another game (both are DRM free) but this time not work or this is my impression.

In short I have tried to call many function adresses (I have used IDA to find the functions) but never trigger.

Now I don' sure if is true that the functions will never called, or my code not work (I suspect the second ...).

I ask if is possible use Cheat Engine or other to add a sort or "Print Debug message".

For example add a message "test" when the function address: 0x043AA30 (sub_43AA30 IDA function name pseudocode) will call by the game.

Is possible do it or similar ?

Thanks !

yes, look at https://forum.cheatengine.org/viewtopic.php?t=615359

Alternatively, you could use breakpoints and in the handler print out info, or even just write to a file
Or you could let your injected dll output something. E.g MessageBoxA(0,"It workes","Caption",0)

Hi Dark byte,

Many thanks for your response !!

The idea of add breakpoints seem very interested and easy to do.

I have tried to find my assembly function with Cheat Engine.

First I have found the start (004F314A) and end (004F32B3) adress with IDA.

After tried to found it with cheatengine:

But don't find the function.

How I can find the function with CheatEngine to add a breakpoint ?

Thanks !
