Cheat Engine

[jeivarmarr]

Hi good day,

I'm looking for help from you, I installed a plugin cheatengine, the name is Stealthedit. which has worked for what I need it, skip the memory protection, the problem is that I want to use the same method in a dll, but do not even know how to start, not that apis used either as makes the jump to the other region of memory.

I would appreciate if you help me to make the code.[/quote]

stealthedit doesn't add any 'jumps' to the original code, it only removes the PAGE_EXECUTE accesses from the memory page that your address belongs to, so that when the program tries to step on any code into that page, an exception is raised, at this point the exception handler of yours will change the EIP to the equivalent address, but in another 'copied' memory page of the original code, no assembly commands gets modified at all,so to change the protection of page, Use VirtualProtect or VirtualProtectEx functions.

also, you need to enable the data execution prevention policy to your target process, use SetProcessDEPPolicy function.

and to copy the game code, allocate a memory with the size of the game image size, then use RtlMoveMemory or _memcpy functions.

finally create your exception handler to filter out ACCESS_VIOLATION exceptions on execution, and install it either Structured or Vectored (Vectored is recommended, see Debugging and Error Handling )

thanks for your answer, but I'm so stupid that I did not understand anything.
only understand how to change the memory protection, would have some form of code already done.
