The game is coming from… INSIDE THE GAME!
Instructables.com member dany32412 has created a fully functional Nintendo Entertainment System inside an NES cartridge. His description of the modification:
Have your ever seen any of “Ben Hecks” portable console builds? Well if you haven’t, he often uses these Chinese Famicom clone consoles. These cloned consoles are often times refered to as NOAC’s, meaning NES On A Chip. They are called this because they are a fully functional Nintendo Entertainment System literally on one chip. The best part about the NOAC is that they include a 60 pin famicom game port, which in our case can easily be converted over to a 72 pin NES game port.
I don’t understand that either. So here’s a video of it in action, for those (like me) who feel like a caveperson trying to wade through CIA security protocols.
