Re: x86 disassembly + reassembly

I was searching too long time for doing this friend, but no success
until now? Did you find the way to do it?
I don't know why this should not be easy and why doesn't there any
utility do it directly.
the disassembler should should know what it's doing when disassemble
and then reverse it.
my problem is different than yours, what I need is to disassemble a
binary add some modifications and correct some bugs then recompile it
again into binary without altering  anything relates to the libraries,
linking nor the CPU architecture.
