Sorry if this is another post about how to play syphon filter multiplayer using ad hoc mode. I know the game is pretty old but I am a noob to the psp. One of my friends has syphon filter and I also have it as well and wanted to play multiplayer by using ad hoc. When I go to ad hoc it shows on both psp's that you are the host. How do you join a host in syphon filter dark mirror?
