I'm working with some x86 assembly code and I need to rip from one executable and paste that code into another.
Originally, I had an executable that was meant to accept two command line parameters and run a handwritten function on them. However, I ran into annoyances with using
GetCommandLine et al. to return the parameters in my ASM. Namely, it returned Unicode and I needed the parameters in ANSI. Rather than dealing with setting up the library calls and converting that way, I compiled a small program that uses command line arguments with the intent of reusing code.
So now I have two executables:
- one with the command line parameters parsed and in their proper places
- two with the actual assembled function code inside of it.
The first executable has the space for the function
NOP'd out, but I need a good way to paste the logic in. I've looked at Asm2clipboard, Code Ripper and data ripper, but they only have the functionality to rip the assembly out, but not paste it back in.
I'm aware I'll have to fix addresses and things like that, but I can't find a way in Olly or other tools to move the code between the executables. I can go into HexEdit or something like that I supposed, but I was hoping there's an easier way.
