Are you planning on doing this to convert from a binary on one machine to a 
binary on another? Is this an on-the-fly translation?

Problems I can think of include the format of the executable for whatever OS 
and hardware is going to load it; proper address correction; proper 
translation between architectures that do not support the same functionality, 
for example going from a CISC instruction set to a RISC one; big or little 
endian orientation problems with both code and data; translating addressing 
modes from one instruction set to another; etc.

For me, the easiest thing to do is recompile the C/C++ (or whatever) source 
code for the target platform. Let the compiler do the hard part. Besides, it 
will probably do a much better job than any translator could.
