This is just a small personal test project building on the work of a others to implemet a SNES controller interface with Arduino (Nano V3 atmega328 ).
First I plan to write a serial interface to simply echo button presses.
Later I hope to be able to attach the controller as a USB HID Joystick by using V-USB.
Finally It would be nice to implement on lower cost hardware i.e a modified USBASP ISP Programmer.
Had a bit of a head ache with the controller plug. I set up a pin adapter with paper-clips and some clip on leads ( from a logic analyser kit). I some how managed to dislodge the 5v rail (in the controller plug) with a paper clip, I suspect that the knock off SNES controller wasn't built particularly well to begin with.
I ended up soldering on a header to the PCB of the controller for testing. I manage to place it so the PCB still fits in the case.
