Well, a software (I.e. a. exe file) is a long list of numbers. Some are commands like “do something when the user clicks there”, some are data, like text on a button.
If you are very familiar with those intricacies, you can change a few bytes here or there to change what the program does.
No, there are tools like “hex editors” that allow to edit a file in a more controlled way. I don’t think opening a binary file in notepad would do anything good to that file…
What exactly does patching a program on the binary level entail?

I’m more curious as to the process than the concept I guess. Open your exe in notepad, hold alt, and mash the numpad?
