One of the newest lighting kits for the Game Boy Colour, the Q5.
These are 15% larger than the standard Game Boy Colour displays and it makes such a difference!
They have been fully set up which means, as well as the adjustable brightness (tapping the top left of the console) and adjustable colour pallettes (tapping the top right of the console) an in-built menu can be opened to change these also, as well as adjusting the screen positioning, 'pixel' model, changing the colour settings, etc.
Press Select+A+B to access the menu.
Press A and B to toggle up and down.
Press Select+B to enter.
Press Select+A to exit.
This one comes in the white shell, black buttons and a glass lens. (Note - the white colour of this shell is more of a cream/pearl white - it hasn't picked up the colour too well on the camera)
