2nes2usb is a firmware for Atmel ATmega8 and Atmega168 micro-controllers which allows one to connect up to 2 NES and/or SNES controllers to a PC using a single circuit.
The device connects to an USB port and appears to the PC as standard HID joystick with 2 report Id's. This means that it looks like 2 controllers in the Windows control_panel->game_controllers window.
Schematic and additional information such as build examples are available on the project homepage:
English: 2 NES/SNES to USB French: 2 NES/SNES à USB
Currently supported micro-controller(s):
- Atmega8
- Atmega168
Adding support for other micro-controllers should be easy, as long as the target has enough IO pins, enough memory (flash and SRAM) and is supported by V-USB.
