[Questions] Red Steel 2 & Monster Hunter Tri & Okami

[suankaew]

I'm using Dolphin r6906
These are my questions.
1. How to configure my XBOX 360 Controller for playing Monster Hunter Tri?
(I don't want to play with mouse and keyboard)
2. How to configure my XBOX 360 Controller for playing Red Steel 2?
(If it can't play with XBOX 360 Controller, How to configure a mouse&keyboard?)
3. How to configure my XBOX 360 Controller for playing Okami?
(If it can't play with XBOX 360 Controller, How to configure a mouse&keyboard?)

I try so many times to solve these problems, but I still can't play these 3 games with my XBOX 360 Controller or a mouse&keyboard.

Thank you for your help
