All paths in the video relate to RetroPie 2.3 (2.4.x and 2.6.0 isnt massively different)

NOTE:
To run the setup scrip listed, you may need to try "cd RetroPie-Setup" then do a "ls -lah" when in there. The script should then show.

ALSO: Check this if you have updated your scripts recently (from early dec 2014 on retropie 2.3)
