4nes4snes if a firmware for Atmel ATmega8 which
|
|
|
|
|
allows one to connect up to 4 NES and/or SNES
|
|
|
|
|
controllers to a PC using a single circuit.
|

|
|
|
|
|
|
|
The device connects to an USB port and appears to the
|
2008-03-30 11:21:39 -04:00
|
|
|
PC as standard HID joystick with 4 report Id's. This means
|
|
|
|
|
that it looks like 4 controllers in Windows's
|
|
|
|
|
control_panel->game_controllers window.

|
4nes4snes uses the software-only usb driver from Objective Development.

|
A good portion of 4nes4snes is based on Objective Development's
|

|
|
|
HIDKeys example.

3) Compilation and installation
|
|
|
|
|
----------------------------
|
|
|
|
|
First, you must compile it. To compile, you need a working avr-gcc and
|
|
|
|
|
avr-libc. Under linux or cygwin, simply type make in the project directory.
|
|
|
|
|
(assuming avr-gcc is in your path).
|
|
|
|
|
|
|
|
|
|
Next, you must upload the generated file (main.hex) to the Atmega8 using
|
|
|
|
|
whatever tools you like. Personally, I use uisp. The 'flash' and 'fuse'
|
|
|
|
|
targets in the makefile is a good example about how to use it.
|
|
|
|
|
|
|
|
|
|
The Atmega fuse bits must also be set properly. The idea behind this is to
|
|
|
|
|
enable the external 12mhz crystal instead of the internal clock. Check the
|
|
|
|
|
makefile for good fuse bytes values.

5) About the vendor id/product id pair:
|
|
|
|
|
------------------------------------
|
|
|
|
|
Please dont re-use them for other projects. Instead,
|
|
|
|
|
obtain your own. I got mine from mecanique:
