Nintendo 64 and Gamecube controllers are excellent controllers which are quite appropriate for many PC games. With this circuit, you can easily modify a controller or build a cable which can connect a Gamecube or Nintendo 64 controller to a PC equipped with an USB port.

Supported controllers:
  • Standard Gamecube controllers (Official and 3rd party)
  • Wireless Gamecube controllers (Known to work with Nintendo's Wavebird and an Intec controller)
  • Gamecube Dance mats (Opposite directions supported)
  • N64 Controllers (Official, and most 3rd party, including the Hori Mini)
  • Should support all accessories acting as a standard N64 or GC controller.
  • Vibration function/rumble supported! Tested with project64 and dolphin.
  • Gamecube keyboard support. Tested with ASCII ASC-1901P0.
Not supported:
  • N64 Memory cards
  • Simultaneous use of a N64 controller and Gamecube controller on the same adapter.
System requirements:
The firmware auto-detects which type of controller (GC, N64 or GC keyboard) is connected. On the PC side, no custom drivers are needed. It works fine with Windows (2K/XP/Win7/Win8 32&64 bit), Linux and MacOS X. It should also work with other operating systems supporting USB and HID joysticks (or HID keyboards for the Gamecube keyboard). Vibration only tested on Windows with project64 and dolphin. Both parts of the gamecube keyboard are supported, but only one at a time. Two adapters are needed to use the joystick and keyboard simultaneously.

This is an open source project. So if you'd like to build it yourself, all the information you need is on my Gamecube/N64 to USB project page.
