1. copy your game to the internal harddrive(Press triangle on the game and go to copy then select the internal hdd)
2. Find the game you want to play in multiman
3. Push triangle and go to game settings
4. Make sure Bd_mirror and internal are both checked
5. Press start
6. You will be sent back to the Xmb.
7. Have any Original disc in your ps3
8. Go to the games column and select your game from the blue ray disc icon
If it throws an error at you or you're trying to run a 3.55 fixed game, just download the games updates using ps3 game updater then install.
