A gaming console is provided which produces audit mode displays via the machine controller instead of the display controller. This arrangement allows a simple display controller to be used for the basically text based display information of audit mode while continuing to allow high quality graphics to be displayed via the separate display controller during a game playing mode. A secure controller 11 runs a game program and generates a stream of display commands 19 to a display engine 18 which then generates the video representation of the game via video output signal 17 which is transmitted to a video multiplexer 14 within the secure controller 11. The multiplexer 14 selects between the game video output 17 and an audit mode video signal 26 under control of an output selection function 12 which is under the control of the secure controller. During audit mode the selection function 12 will cause the second input signal 26 to the multiplexer to be displayed, this second signal being generated by the lower performance display controller 13 contained within the secure controller 11.
