That is the domain of transistors, resistors, capacitors, and so on. That path will not make you a game programmer. If you did work on those systems in a game console it would be only for a very limited function; you would be one member of a team that works on the audio subsystem of the console.
If you want to make hardware you study computer engineering. You do not need any of those skills to be a game programmer. See the Forum FAQs section 1.
Thank you...Could you possibly recommend me any books on computer hardware engineering?
That being said, I wouldn't start down that route with a college book. You are better off starting with a "My First Microcontroller" style project book that comes with a bunch of components. You can get them at Fry's, or Radio Shack, or other stores that sell electronic components; you may have to go through their online sites to pick them up. There will be projects like making a single blinking light, or a single buzzing noise.
