The video game cyborgDino created is called Axis. In order to remove the book without damaging the magazine, the reader had to bend back the silver staples, gently pull the book out, then bend the staples back into place. With a bit of help from the UnoJoy library, it was a relatively simple matter to make the Power Pad work as intended. The Nintendo Power Pak Source was a complete directory of all NES game paks released up until 1990.It was published inside Nintendo Power magazines volume 11 in 1990. Like all NES peripherals, the Power Pad stores the state of its buttons in a shift register that can be easily read out with an Arduino. The first order of business was to read the button inputs on the Power Pad. The guys over at cyborgDino thought they should celebrate the sliver anniversary of the Power Pad by creating its 14th game, using an Arduino and a bit of playing around in Unity 3D. In total, only six games for the Power Pad were released in North America, and only 13 worldwide. Released 25 years ago, the Nintendo Power Pad, a plastic mat that plugged into an NES, saw very limited success despite its prevalence in basements and attics.
