Hi, I need help setting up my PS3 controller on the PC version.

Before anyone suggests different software and stuff, I already have the controller "working", the problem is that I cant figure out how to change the settings so that battle works via the PS3 controller.

For example on the PS3 you hold down L2 or R2 then press one of the buttons to do an attack, but I cant find any way to set that up, or any way to change the on screen display to the way it looks on the PS3.

I would be immensely grateful for any possible help as I am almost positive that im just missing something, and that what I want is possible.

So please can anyone help me?
