How To play multiplayer with only one copy.

*THIS DOES NOT WORK WITH ALL GAMES

a) Only one copy of a game

Load the game on one PSP, set to host a multiplayer game
Eject the UMD and put it in the other PSP load the game and seek.
Start the game!

b) Two copies, different regions (this works with more games)

Load the game on one PSP, set to host a multiplayer game
Eject the UMD and put it in the other PSP load the game and seek
Change the UMD in the second PSP to the other second copy (different region) and put the first copy back in the first PSP.
Start the game.
