How to view machine code?

Question

Programming

I know there is such an assembler thing, but I would like to know if a program that opens pure machine code, for example, I have a picture, I want to open it and see how it looks from machine code.

Answer 1

Any hex editor will help you see the image as it is represented in the computer's memory.
Nobody programs "in machine code". Maximum - patches. Machine code is divided into data and, directly, the code that is disassembled (transferred to a higher level of abstraction).
