Here is my retroarch.cfg file:
http://pastebin.com/zBByPybD
My input is as follows:
Up, Down, Left and Right = The Arrow Keys
Start = R
Select = Q
A = Z
B = X

If it matters, I am using the default NES emulator, I don’t know if that would change anything?

Thanks again,
Josh
PS: It had only just occurred to me that I said rshift was select, that was in the Retroarch Config file, not what the actual inputs were through Emulationstation…
