@AdamBeGood as far as he is not able to give some Information about his setup as mitu requested he might also not be able to configure a keyboard.
I guess he wants a plug and play system and uses a prebuilt image without carying about how things are working.
I recommend to buy a Nintendo or Playstation.

@3D-George Looks like you enabled Kiosk/Kid mode and this hides the RetroPie menu. Did you do that ?
Can you add more info about your system - https://retropie.org.uk/forum/topic/3/read-this-first. How did you install it ?
