Sorry for the late reply.
Thanks for your replies Herb and Petro.
As I am new to this I didn't want to do something I shouldn't be doing but after a lot of reading on the web I have made my mind up on the moral side of things with the roms.

I have figured out what files I need but haven't had chance to try them as yet.

I have a Wii u pro controller and wanted to know if the joystick part of the controller doesn't work to control the games is it possible the make them control the movement of the game.

I have been spending most of my time fixing the sound and tv resolution in retropi and all is well with the pi now :). Have to admit even though I struggled I have enjoyed learning something new :). I'm going to buy the book on pi projects next :)

@markyh444 haha whoops. Leave it to me to miss the big red ban flag next to the name lol

Please don't sell a legal arcade machine then just give your customers ROMs because you're a great helpful guy. That's still copyright infringement, is harmful for RetroPie to be associated with, and the setup script explicitly asks you not to do this.
