Hi,

Im newb with ollydebug, and i cant find some things...

like, when im editting a .exe file of a game, and i want to remove the hackdetection, i already found what part it is, but i dont know how to remove it or something? Can i just set a breakpoint or something?

And, how can i like Save my file when im done?

tnx

yeah you can always do something provided you know what to do
a debugger is designed to be able to set a break point
so ollydbg can set them too and that too in innumerable ways you could ever think of just try hitting f2 for a start then keep right clicking
you will find a breakpoints menu choosing that should open a pandora box
of option for you select and break

as far as saving the modification is considered
right click --> copy to executable --> all modification OR selection
ok--> in the new window that pops up right click --> should see save to executable give a new name and hit ok

Yes, well.. im also new to debugging, not just ollydbg.

But, when i set a breakpoint, i cant run it anymore...



how should i remove stuff from it?

When you set a break point, at least temporarily, it is modifing the code (for the int 3 instruction). It sounds like it is checking for modifications. If you place a hardware read break point on where you set the software breakpoint, you should get a hit at where it's doing the CRC (or what ever method they are using). NOP the final failure, and put a hardware break there, and see if someone is checking the checker.

1st of all there is nothing like Removing in Debugging because the complier read the code and translate it to Assembler which work with
CPU-Memory-I/O
Inside the CPU you got the process counter(PC) that reads each the memory from 0000- to the end

so you can't just delete some line it works like READ and done
but you can use some command called nop that tells "Do nothing"

"Removing"

Right click > Binary Edit(or something alike) > Fill with NOP's
or Fill with zeros (for certain things)

Saving

Right click > copy to executable > ........(whatever needed)
