Ps3 Controler?

I finally figured how to use my cousins psp to do remote play on my ps3 I wanted to know if his psp could be used as a extra controller for use to play ps3 game that don't require a right analog stick (like Little big planet,etc)

anyone know?

no because the remote play doesn't support PS3 disc-based gameplay. But it can be used for other features and other game such as PSN games or PS1 games
