During the Maximillian Galactica case, you will hear a clown’s testimony. Amongst his testimony is an edited version of the Fresh Prince of Bel Air theme song from the television show.
Remember that you don't have to wait until the end of a sequence (such as an investigation sequence or a part of a trial) to save your game. You can save your game, quite literally, at any time by simply pressing the Start button. This will bring you to the menu where your game can be saved. After saving, you'll be brought back to the start menu.
There are four cases total in this game. To unlock cases, you must successfully complete the case before it. Once a case is unlocked, however, you can go back to it and replay it at any time.
