Secret - Play Multiplayer with one disc. | |
| It's simple. First, the host must create a game. Choose all the settings, etc, and actually start the game. Then, pop out the UMD, and give it to a friend. Your friend simply loads up the game on his PSP, and then joins your game. This can work with several people in the same manner. However, setting the frag limit high is a good idea, because once the game is over, you have to redo the whole process, because the game needs to load again, and cannot without a UMD. | |
