usnes is a driver for the Super Nintendo controller, connected over GPIO on the Raspberry Pi. It uses the Linux uinput interface to emulate a USB input device from user space. usnes will work with unmodified SNES controllers, provided you are able to connect them to the Pi's GPIO pins.
Below is the pinout for the SNES controller (copied from
http:/www.gamefaqs.com/snes/916396-super-nintendo/faqs/5395). You will need to
connect the clock, latch and data pins on the controller to GPIO pins on the
Pi, and tell the daemon about the mapping. This can be done by editing the
controller array in config.h.

Pin Description Color of wire in cable
--- ----------- ----------------------
1 +5v White
2 Data Clock Yellow
3 Data Latch Orange
4 Serial Data Red
5 ? No wire
6 ? No wire
7 Ground Brown
NOTE: I have had success driving controllers at 3.3v, but as always YMMV.
Do not connect pin 1 to 5v unless you know what you are doing. You may break your Pi. I take no responsibility for what happens.
By default, usnes emulates a single controller with the following button/key mapping:
SNES BUTTON KEY
----------- ---
A a
B b
X x
Y y
L l
R r
D-Pad Up Up
D-Pad Down Down
D-Pad Left Left
D-Pad Right Right
Start Enter
Select Escape
This can be changed by editing the controller array in config.h prior to
compiling.
The bcm2835 library is a dependency. It should be installed prior to building.
