Raspi in a Stick

Sonntag, August 20th, 2017

raspberry modding is everywhere. So we put a raspberry in a NeoGeo Oldstyle Arcade Stick for presentation at GamesCom 2017, so the younger games can get in touch with the neo-geo Games and not only with the look. With the right feeling a original NeoGeo Controller

The position makes it possible to use the onboard USB Ports and  network connector.

First some dremel work to make it fit into the neogeo arcadestick case



then a hdmi slim extension and a usb cable


As the NeoGeo X Controller is a standard USB Controller it was possible to connect the usb part directly to one usb connector of the pi


in the future it could be possible to make the buttons directly to GPIO Ports

So it looks great
