From Rear Held CartridgeBen Heck, super duper console Maker made a Micro NES – a full NES for the palm of your hand, he writes “Sometimes my creations have elaborate origins, like “I’ve been working on the idea for 15 years” or it came to me one day in the bathroom. (Bathrooms and cars being places where I have most of my best “idea bursts”) But I’m sorry to say the NES Micro had no such “stroke of inspiration” behind it. Rather I just had an extra NOAC (NES-on-a-chip) Asian joystick game laying around and figured I may as well do something cool with it instead of letting it collect dust.” Thanks Unigamer! Link.
