The first 5 extra options are time released. After every 3 hours of game time (a clock in the extra options screen keeps the time) an extra option will be released. After 3, 6, 9, 12, and 15 hours you get an option. They will not appear automatically, once the clock passes 3, 6, 9, 12, or 15, you must enter a one player game mode, and either win the mode or lose on purpose, so that you will go back to the title screen. It will then say "Extra config open"
