Is there any way to make the camera in 2.49b act like it acts in 2.63? Mainly rotate around the object with the mmb?

I am forced to use 49b due to some importerting tools not being available for 2.63.

2.49 is just unusable and everytime I havet to rotate the camera it makes me want to stab 2.49 and it's family to death.

Old Blender does not have re-mappable hotkeys. Anything you can change is in User Prefs.
