Read Sega Genesis (Mega Drive) controller and use it on a Neo Geo MVS. This project uses Jon Thysell "SegaController" library in order to function. Check it out at: https://github.com/jonthysell/SegaController
- Download the SegaController.zip Library from https://github.com/jonthysell/SegaController/releases/latest
- Open the Arduino IDE
- Open "Sketch > Include Library > Add .ZIP Library..."
- Select the zip file you downloaded in step 1
The SEGA Controller pins are as follows, looking face on to the (female) DB9 plug:
5 4 3 2 1
9 8 7 6
- Connect pin 5 to Arduino +5V
- Connect pin 8 to Arduino GND
- DB9 Pin 7 -> D8
- DB9 Pin 1 -> D2
- DB9 Pin 2 -> D3
- DB9 Pin 3 -> D4
- DB9 Pin 4 -> D5
- DB9 Pin 6 -> D6
- DB9 Pin 9 -> D7
The Neo Geo MVS pins are as follows, looking face on to the (female) DB15 plug:
8 7 6 5 4 3 2 1
15 14 13 12 11 10 9
Connect the Arduino to the NeoGeo MVS plug as follows:
- Connect Arduino +5V to MVS pin 1
- Connect Arduino GND to MVS pin 8
- D9 -> MVS 11
- D10 -> MVS 04
- D11 -> MVS 12
- D12 -> MVS 05
- D14 -> MVS 09
- D15 -> MVS 02
- D16 -> MVS 10
- D17 -> MVS 03
- D18 -> MVS 13
Finally, Solder a 0.1uF 0805 SMD capacitor (or tantalum one but leaving the leads very short) between GND and 5V at the Arduino pins. This is known as a "bypass" capacitor, it is not compulsory but it is highly advised.
