This is a dream comming true. When I was ten, I was facinated by these games. With nodeNES I could really understand what was happening underneath the cartdridge. How NES works and how game programers were made. Back them they were made of blood and steel. Blood of countless game lifes wasted in the first level, witch didn't have easy mode. And Steel from cartridges forged in the fire of mount doom.
Nowadays anyone can write an "if" and praises theirselfs as programmers. They have tendencies to curse every high level programming language for their own faults.
