I was into console emulators in the late 1990's and believed even at that time that it was possible to know everything there was to know about the NES. So given that we're a couple decades plus later and random hackers at home are still digging up interesting information, I feel like the tail on this kind of thing is quite long. (And I'm still continually surprised that 80's-90's retro gaming/computing as a whole is such a popular hobby! If my teenage self had a crystal ball, he would have been very pleased to learn this.)
