PS2 games on a PC (Psychonauts)

[tbaher]

Some games are designed for a console. But they are also released on a PC. PC usually has better graphics, etc. So I get the PC version. I have a Logitech Rumblepad 2 to best emulate a PS2 Controller (short of a PS2 dual shock USB adapter)

Here's my question: Does anyone own Psychonauts on the PS2? Can you post the control scheme so I can map it?

eg:
X: Jump
O: Use
Start: Options screen

thanks

PS: I usually look in gamefaqs. But no faqs yet for this game.
