All? As the Mega Buster displays his life energy in the pause menu and the gauge in the buster and his life gauge are similar, I assume his Life Energy and the energy from his buster shots use the same energy source, so as long as he is functioning, thus why he can shot any number of times from the Mega Buster, while Special Weapons are limited (although not shown, the buster might display the energy from the weapon when it is equipped?). In Super Adventure Rockman, one scene shows the gauge in the buster lowering with each shot, indicating that he is running out of energy.
