He writes that he made it himself. It is a very simple project since there is no encoder in standard MSX and Neo Geo controllers so it is litteraly just a box of wires. 7 wires should be enough for MSX with 2 buttons. So it is a great project if one wants to build. It'll be a lot more work to make it look pretty and slick then to actually build the insides of the adapter.
I Got You. I am looking for to create an adapter with the same JoyMega that has the possibility to use all the buttons but I will have to study the functionality of the NeoGeo joystick to do this.
