    Stupid question, how to remove stuff?

    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

    Stupid question, how to remove stuff?

    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.

    Stupid question, how to remove stuff?

    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)
