Just noticed in the config file that there's an option to use NES instead of SNES controllers... what's the pinout for this/is anyone selling connectors? I've had a quick look on the site and can't find it on the site or in the readme.

Personally, I use a retro adapter, it's nice in that with adapters it can run a large number of diferent controllers. The build quality is a bit on the weak side, but just be gentle with it and it shouldn't be a problem.

I wanted to order a Retro Adapter but was told they they are out of stock and will not be produced any more.
