Hello ! You can change the camera while you are in game : that is to say, you're playing against someone (AI or Human), you go in the menu and you can change it.
By the way, you can only change the camera if you play in 3D. In 2D mode, you can't change the camera, so it will be different on every court of the mod.
About the port, I'm not an expert so I can't help you
