How do you use ad hoc mode on psp

ok i guess i have done this a lot but you have to have 2 psp's on the same channel (go to automatic under network settings in settings, go to ad hoc mode then automatic) you both have to have the same game unless they are game sharing compatible on back of box. but anyways just go to multy player in the game on both systems and go one join game and the other host game and you should be set.
