Thanks so much dude. I just finished the game and i think it was pretty good! if you want you can play it and thanks for ALL the help! Im currently working on my next Shooty Block and if i ever need help i know i can count on ya.
While hardware isn't my area, my son has been learning electronics from this youtube series that says they will conclude by creating an 8-bit computer. Maybe that will help?
