HFD activates the hyper slightly early, and dows the tap A method on both the right arm and the main turret. i guess hyper activation is based on where the shells appear? ie if before you destroy the main turret and the shells appear to the right of you, you can hit those and not damage the main turret whilst travelling to the right handside

you can probably activate a hyper really early on this guy and get used to some of the timings. i bet people don't do that though because it would be impossible to chain the first two turrets on those horizontal things after the 1up in a non hypered state
