mc cthulhu and crossbone compatibility question

was wondering if these two pcbs are compatible with each other or will I NEED an ps360+ for the crossbone? I already have a mc cthulhu installed for ps3, just looking to save some money and time (waiting) instead of getting a ps360+.
And if they are compatible, is the install somewhat the same as in this youtube video by lemony vengeance https://www.youtube.com/watch?v=ZiV9PaB6oX4 ?

Thanks
