NES Emulator Enhancer

I have installed Nestopia NES emulator on the ATV1 and am quite adept on how to use it. I have installed files via FTP and can retrieve them quite nicely. However I would like to use my NES usb controller. I use the controller on both my iMac and MacBook Pro just fine. I am aware that to use the controller Emulator Enhancer must  be placed intact in /Library/Application Support or ~/Library/Application Support. I have done this via FTP using Cyberduck and the file is in the correct folder on the ATV1. I have rebooted and have launched the Nestopia .app and then have gone to preferences and to joysticks and nothing appears. Is there something else I need to do? Can anyone give me some guidance. So come to think of it, I am not very adept!
