You have four options on your screen brightness when you have your AC adapter plugged in. You regularly have three, but the fourth add on is a brighter one. So if you want a brighter screen and have access to an outlet and happen to have your AC adapter handy, then you know what to do. Just press the screen button until you get the brightest screen.

Simply play your PSP on the lowest brightness setting, with either 1 or 0 bars of sound, and you're guaranteed to at least get an extra hour into your gameplay.

simply HOLD DOWN the screen brightness button for 3 seconds and voila, screen off, enjoy your mp3 or internet radio without all the unnecessary battery drainage

1.To Play let your friend borrow a game with multiplayer and let them work on it.

2.When you want to play multiplayer simply have your friend pause (while in game) or when at menu take out the game and they'll be able to continue.

3.Lastly put your game back in and go to multiplayer option with your friend (as in one makes a game the other joins it) and vuala do as you normally would if you both had the game.

Note - this may only work with certain games.
