Where are the Bullet PHysics buttons in Blender 2.5?

Where are the buttons in this panel in Blender 2.5?

I can’t seem to find them.

From the top of the blender window, change from ‘Blender Render’ to ‘Blender Game’. Then look in the physics settings.

Thankyou.

That’s just what i needed to know.

You can use hard-body physics with rendering, but I guess I am usinf them in the game engine anyway.
