PSP as joypad for emulators on computer?

is there a way to play emulators with a psp.
as in.. the psp is the controller. sorta how u can use a ps3 controller and 360 controller in the computer
but maybe the psp can be used as adhoc or maybe even through usb. if there is such a program then please tell me?
sorry if this topic has already been asked/said, i was searching the forums and found nothing of psp as controller

edit: ok i found one.. but its for PC. i am using a mac..

Even if it's possible, that's useless. An Xobx 360 controller is A LOT better.
