Plug your controller setup in your Pi without any other controller except the keyboard, boot it up, close ES and run this

ls /dev/input/

It should show all input devices of which joysticks/joypads are shown as jsX (eg. js0, js1, ...).

If it is not present, try to look if the USB device is present with

lsusb

If a controller is present and you want to test if the device translates the PS2 buttons correctly, run this and test

jstest /dev/input/jsX

Never mind, I didn't realize when I saved the python script it saved additional embedded formatting. I just had to download a straight text editor and it is working fine. Thank you.

What game was it? Can't see what you were talking about any longer :)

It turned out that I was just using a cheap ass micro USB cable, when I replaced it with a quality one the issue stopped happening, thanks anyways guys

A normal pi (not zero) supports analog over CVBS but its interlace so it will look shimmery.

I believe it may be possible to get it to output 25p over HDMI, convert to VGA, then convert to RGB on scart lead using a cable like this http://www.ebay.co.uk/itm/Cable-VGA-RGB-ARCADEVGA-SCART-CON-JACK-SONIDO-EUROCONECTOR-JAMMA-ARCADE-/131577748414?hash=item1ea2a51bbe
