| Project overview | [hide] |
Nintendo 64 and Gamecube controllers are excellent controllers which are quite appropriate
for many PC games, and of course are perfect for emulators!. The microcontroller
firmware in this projet implements a standard HID joystick which means that no
special device driver is required. It works perfectly well under Linux and Windows.Features:
Why? One of my friends wanted to play Nintendo 64 games on his PC using an original controller... so I developped an adapter for doing this. But since Gamecube controllers use a very similar protocol, it was easy to support Gamecube controllers too. Gamecube and Nintendo 64 controllers both work at 3.3 volts. But on the USB bus, only 5 volts are available. For this reason, a voltage regulator is required. Apart from the different firmware, this is the only difference (and additional complexity) this project has with my Nes/Snes controller to USB project. |

 Comments: Some webpages mention that the Gamecube controllers work at 3.43 volts, some other pages says it's any voltage between 3.3 and 3.8! volts... I read an old message in the comp.emulators.game-consoles news group where the author said that the Nintendo 64 supplies 5 volts to the controllers (Wrong!). I measured 3.36 volts on my N64 so personally, I choose to supply 3.3 volts to my Gamecube and N64 controllers. In order to obtain 3.3 volts, you can use a fixed voltage regulator such as the 78M33C or an adjustable voltage regulator such as the lm317 or lm1117 (exemple). If you use an lm317 variable voltage regulator, here's a simple tool which can help you find a good value for R1. Any voltage between 3.26 and 3.40 volts should do the job. |

Bottom  Here is a wiring diagram for the board:  And finally, here are the gerber files which you can use produce this PCB: multiuse.zip Due to the fact that this board is two-sided and has numerous vias, building it at home may be a little harder than the ususal. If you want, you can get professional PCBs from my online store. The PCBs from my store, however, are a little older than the one above. I've had a huge quantity produced with a small mistake: The 5 volts supply from the USB bus does not reach the regulator! In order to correct this, a small wire has to be installed on the bottom side:
