When the first menu comes up, select CATS. After the Main 
Menu comes up press the down arrow past Languages and it 
highlights a red button on the bottom left. There is a game 
hidden in there. Answer all the questions as CATS and it 
gives you a congratulatory greeting. Select Dog and calls 
you an imposter and takes you to another game. Answer them 
as DOG and it takes you to the DOG Main Menu set-up.
