The thing that stands out the most is the number 6, this 6 represents the line of code that you will need to look for and enter. 6 for me would be 4939, and that is what I will enter into the keypad on the right hand side, once entered hit the button on the left (okay) and it will ask you for another set, but with a different number instead of the 6, repeat what you did with the steps ahead, after 3 tries, it will kick you out if you got them wrong, or it will allow you to enter the character selection screen.
