Glitches

2.Create a game on Ad Hoc mode and start the game.
3.After the game loads, take out disk.
4.Put game in another PSP and load up game and join the multiplayer game that's been created and Join in and load up the game.

Now you both will be able to play the game in multiplayer mode. This trick can work for more than two players but the max number of players possible is 6.
